The Problem With Housing

Introduction

Paul Mason’s report on Channel 4 News on the day the Torreys’ announced a poly pledge to widen Right to Buy to housing association tenants was spot on and demonstrated why we have a housing crisis. This policy pledge will only make the UK’s housing crisis worse. We need more social housing not less. Councils need to get building houses again and doing it well and doing it on a big scale. What we must avoid doing is giving away precious social rented housing assets in return for a few votes at an election.

Housing squeeze

Successive governments have relied on the private sector to deliver the bulk of our housing supply and this strategy clearly is not working. The UK is growing at the moment by around 450,000 people a year and yet house building is running at about a two-third less capacity than that during the 1950’s and ‘60’s. Only by building more homes such that we can catch up with the level of demand, will we start to bring the hyperinflation of real estate under control.

Private sector house building is not a means to achieve cheap truly affordable housing. Even if a developer is made to deliver some percentage of so-called ‘affordable housing’, it is by no means necessarily what it says on the tin. Affordable housing is usually taken to mean eighty per cent of market value, but when market values for a modest family home reaches the kind of levels we are seeing particularly in London and some other parts of the UK, very few people will be able to afford the size of mortgage required. The need for a proper supply of social rented accommodation is acute.

Society needs to make a value judgement about how much it chooses to spend on housing and housing infrastructure. As such it is a highly charged political issue. It is something that will require huge public investment and it needs to be paid for over much longer terms than a five-year government cycle. Housing should be built to last for many generations to use.

Housing also needs to be done well and we certainly must steer clear of lurches towards creating social housing ghettos. The UK has a rich history of housing projects and from that there are successes and failures to learn from. The best housing projects were those that mixed social housing seamlessly into the mix of desirable places to live. London is full of fine examples of where council housing exists side by side with private. That legacy has made for healthy and vibrant communities and some of the most sought-after places to live for everyday people.

Cheap to Treat and Cheap to Heat

cheap to treat cheap to heat
Above: BBM’s The Nook Eco-retrofit was a great success in terms of achieving an eight per cent carbon reduction in heating energy requirements but it wasn’t cheap. When it comes to low carbon refurbishment it turns out there is a huge variation in the cost and difficulty of treatment from one building to the next. Image: © BBM Sustainable Design Ltd.

Again this week I met a couple that had recently bought an older house that they were finding intensely cold and very expensive to heat. They had recently bought the property and this was their first winter in it and yes, they were wearing very thick jumpers. They had a £100K to spend on refurbishing and making it energy efficient but to my eye I realized immediately this house was not cheap to treat and would probably never be truly cheap to heat. If you want an existing property that is both cheap to treat such that you make it cheap to heat, you better look with a discerning eye. Here are my top tips:

Don’t stretch your budget too thinly

It is fair to say that the most common enquiry an architect will receive in the private residential sector is a couple who have bought a house and they want to add an extension and they want to make the rest of the house more energy efficient. Nine times out of ten, their budget will be insufficient to do both elements well and normally they end up just making the extension and the house remains expensive to heat. Would it not be better to find a house big enough for your needs and then plan a really good energy efficiency refurbishment that you can afford? I think in the energy starved future ‘adding value’ to a house in real estate terms will not just be about how many additional rooms you may have added but to demonstrably show how energy efficient and cost effective the building is to live in.

The less surface area the better

The humble mid-terraced property is your best bet because you simply have less external wall to insulate. However be careful of terraced housing with large rear extensions – with their shallow narrow but long floor plans and lots of external walls they are particularly parky in winter.

Steer clear of charming but fussy architectural detailing

If the property has lots of charming but fussy architectural articulation, this will likely be expensive to deal with when it comes to insulating the walls. If it is on the outside you may also find the local authority are not too keen on you changing it or covering it over. If you are insulating on the inside, you may override the charm of the period features.

Eek out a timber frame

Importantly for a refurbishment, it is usually easier to carryout an energy efficient refurbishment on a timber frame building than on a masonry one and the key to that is ensuring you keep the constructions BREATHABLE. However in the UK there has been a lot of predominantly unwarranted resistance to the establishment of a modern timber frame construction. It is true a lightweight timber frame building can be prone to overheating if the glazing is poorly protected against too much unwanted solar gain and/or the structure is under insulated. That said it is quick and easy to heat up.

There are a lot of people who espouse the benefit of heavy thermal mass when it comes to energy efficiency – solid brick, stone, blockwork or concrete will give you that. The idea being is that once you’ve loaded up the internal fabric with the heat energy or ‘coolth’ to provide thermal comfort, the building will not be too much affected by big fluctuations in outside air temperature between day and night. Of course this also means you have to insulate to the outside of the mass really well so your building does not hemorrhage the energy. This has to be taken with moderation. Too much thermal mass will give you internal condensation issues, particularly in the warm season – counterintuitive tough it may seem. It will be interesting to see what the insurance industry makes of poorly conceived eco-retrofits of traditional brick buildings relative to well designed timber framed houses in the years to come.

Avoid buildings where internal insulation is the only allowable solution

When it comes to insulating external walls it is always more efficient and safer to insulate on the outside of a property than on the inside faces. If you insulate the inside faces you will have the risk of creating stale moisture behind the cladding and this may lead to mold growth and possibly fungal attack of the building fabric. Conservationists should take note that if you insist on a brick or stone building being insulated internally, that stone or brick will stay colder and wetter for longer with an increased rate of frost damage. If you have timber joists socketed into the brick, these should be cut back and the load transferred to the sidewalls and that is expensive to execute. The best type of internal insulation is a breathable one. If you can get the moisture in the wall to transpire to the inside as well as the outside, it should be safer. The only other watch point is not to insulate internally too much. Super insulating on the inside of a masonry building will increase the risk of defects arising. The aim should be to just to take the edge off those ‘stone cold’ surface finishes. Calcium silicate boards, mineral quilt and cork linings can achieve just that.

Hunt for a property with plenty of access to the sun

If you want to take advantage of free energy from the sun, look for a property with plenty of sun. A south-facing slope with little overshadowing buildings or trees is ideal. Also check how the building is orientated with the sun. If you have large amounts of glazing facing south then you can look forward to plenty of free passive solar heating in the colder months. South facing glazing is also easier to protect against too much solar gain in the warmer months with external blinds, shutters or even foliage. East and west are tricky as the sun is lower in the sky. Large amounts of west facing glazing are perhaps to be avoided or changed. Check out the roof and make sure it can accept plenty of solar panels with minimal overshadowing and predominantly facing south. Hips, dormers and chimneys are not great when it comes to an efficient array of solar panels.

Climate change adaptation

The experts say our weather patterns will change quite significantly over time. There will be longer and more intense periods of sun and rain that in turn will stress a building’s fabric yet further. Older buildings may yet perform better than some of our more recent commercial offerings particularly in protecting the occupants against unbearable overheating. If many of our houses then require energy for comfort cooling in the summer as well as for heating in the winter, our efforts towards creating cheap to heat buildings will be environmentally meaningless.

Avoid deep floor plans

Why is it so many people want a large extension that makes for a really dark interior? Once you create spaces much more than say five metres away from a window, you end up with dark interiors and having to have lights on most of the time. You lose a sense of well being in such spaces. In such instances maybe consider the motto, ‘less is more’ or ‘small is beautiful’. Clever design can of course make even small spaces a joy to be in.

The golden egg of eco-retrofits

With all the above in mind, what you really need to find is a timber framed mid-terraced house with no back extensions, a good expanse of glazing facing south, little or no neighbouring overshadowing and a well designed floor layout affording good daylighting levels inside.

The Armchair Climatologist

armchair climotologist

Introduction

Is manmade climate change something we need to worry about or is it an overblown myth? We only have one livable planet to pass onto our children and yet so many of us feel we are expert enough around the field of climate and environmental science to refute what the vast majority of the real scientists are telling us. It is a head-in-the-sand attitude and arguably a reckless one. Thus we see the rise of the armchair climatologist.

That the world’s climate is changing is irrefutable. There is also an overwhelming scientific consensus that the changes are linked to global greenhouse gas emissions that result from human activity, particularly from the use of fossil fuels.

Bill Gething, from Design for future climate

Opportunities for adaptation in the built environment, June 2010

There can always be a smidgen of doubt about man-made climate change, a bit like the conspiracy theory suggesting man didn’t land on the moon in 1969, and it is that tiny raft of doubt that the sceptics cling to. For those desperate not to have to curb their consumption heavy lifestyles, the climate change sceptics are like heroes; loan voices that speak out bravely against a huge tide of gloomy environmental forecasts. It is the argument they want to hear and all of a sudden they are an armchair climatologist; assured enough in their mantra to lambast the need for things like wind farms, kerbing their use of cars and energy efficiency in the built environment.

As the preeminent species on the planet we ought to recognize a responsibility to be good custodians of what we consider our dominion. There are enough of us around calling for a global consciousness of our unsustainable development and how it should be redirected. One gets the sense though that most people on this Earth are working on instinct either unable to have that awareness or not wishing to accept it. Our news is full these days of those trying to make ends meet or even just survive. You can forgive them for putting such awareness to one side when they have very immediate and overwhelming concerns. Being so disempowered, it is hard too for those of little means or voice to do something requiring such enormous reorganisation of the social-economic norm. But you can see instinct at work and suppressing a global environmental awareness in cultures of affluence as well. Here in the west it is all about overstimulated consumption where commercial energies exploit the consumer’s in-built desires for self-satisfaction and social pre-eminence.

The trouble is with our self-satisfied head-in-the-sand approach is that ecological responsibility gets past to the next generation to deal with only their sacrifices will be far greater than if we take the necessary action now.

RIP Code for Sustainable Homes

RIP code for sustainable homes
Above: This diagramme prepared by the BRE is a representation of what issues of sustainability are being lost to regulatory control through the abolition of the Code for Sustainable Homes.

If one ever needed hard evidence that we as a society are not ready to be sustainable you simply have to look at what sustainability issues have been ejected from regulatory control because of the abolition of the Code for Sustainable Homes. Government has been keen to unlock the obstacles to house building and besides the obvious land supply and planning control issues they have been directed to the extra development costs involved in meeting the various levels required within the Code for Sustainable Homes. So in a way, it means that even with new build, start from scratch projects we have found excuses not to be as sustainable as we can be. What example does it set that as a developed country we cannot afford to build to environmentally sustainable standards?

The real issue is not that we supposedly cannot afford to build to truly sustainable standards, it is that we as a country decided to leave the supply of social and affordable house building to market forces. We need public money going back into building a large part of the housing supply and fast.

Comstation; Saviour of the Commuter Belt?

Introduction

The idea of living in a leafy suburb and travelling large distances to work in the heart of a bustling city has very much shaped large urbanised areas around the world in a very particular way and that mode of life which involves ‘the commute’ is now an entrenched societal norm for millions of people. The town and country idyll however does have its downsides, one of which is that it is incredibly energy inefficient and therefore at odds with our efforts to exist within the ecological limitations and energy reserves of our planet. It is a way of life that was made possible by the machines and technologies of the industrial revolution. We are now very much living in the next epoch, that of the information age. So is it not daft for so many to commute such large distances and using so much precious time and energy each day just so we can sit behind a computer in a building far away from home?

Interrogating the validity of the commuting lifestyle as we entered the Twenty-First Century was for BBM a critical environmentally minded imperative. In the mid to late 1990’s BBM were in turn inspired to launch an initially hypothetical research project called Cityvision. At its core was the idea that information technology could reduce the need for the daily commute and to those ends how buildings and urban structure could play a role in supporting lower energy lifestyles. Out of these studies one idea, nicknamed ‘Comstation’, was targeted directly at the commuter belt where it was hoped it could unshackle the train using season ticket holders and long distance car commuters from the drudgery of the daily commute and help save copious amounts of carbon emissions to boot.

Would it not be great to have a place where one could rent a space to work, to conduct meetings, have a child in a crèche, go for a coffee or a sandwich or even take half hour out to get some exercise in a pocket gym? There could be an I.T. doctor on hand to sort any technical glitches you might be having with your computer and all this could be where you would normally catch a train from. How about if your season ticket also allowed you use of the facility, such that you had no qualms about losing out on the reduced usage of your rail travel?

The rise of commuting

It could be said the British invented commuting. After all where was the first underground railway built? We certainly had great railway engineers and headstrong railway companies to create the means to transport large numbers of people in from satellite villages and towns into the vibrant and dynamic hearts of the big cities but we also invented new planning ideals such as leafy garden cities to capitalise on the new mode of life. Pioneering thinkers and planners like Ebeneezer Howard through is hugely influential book published in 1898, Tomorrow: A peaceful path to real reform (reprinted in 1902 as Garden Cities of Tomorrow), sold a plan that combined the best of ‘town’ with the best of ‘country’. The London Underground sold the idea of ‘Metroland’. The developers and transport companies did the rest and created the cities and crucially the lifestyles that dominated the Twentieth Century.

The carbon cost of the daily commute

Let us analise a typical long distance commute from the point of view of its carbon footprint, for instance Brighton to London Victoria which is a round-trip of 177 kilometres.

This is the paradox, why expend (in this case) 2700kg of carbon per annum in simply getting an employee to a computer to do the work from? Yes, it is of course true that there are many jobs that one simply has to commute to and for those, hopefully we can afford appropriate and affordable housing close to those places of employment. Yes, it is also true there is fear of isolation from the employee and fear of losing management control by the employer but such concerns can be addressed. Indeed there are many types of work that, with a change of attitude from employers and employees and perhaps new forms of work management, could easily accommodate less energy hungry commuting patterns.

The economics of commuting

commuters
Above: It is not just the cost of commuting which weighs heavily on the minds of those who pursue the live/work balance of a town and country lifestyle but also the stresses of peak time congestion – a real quality of life issue. Image: © BBM Sustainable Design Ltd.

People do a long distance commute for many reasons, lower house prices, possibly better local schools, access to the countryside, better air to breathe and have all this whilst maintaining a job in the heart of a city with a relatively high paying salary and possibly the kudos and fulfilment of working for a leading company in a given field. Most commuters though would concede that they constantly assess if that best of both worlds lifestyle is justified by that bit of the equation that makes it work – the commute or more precisely the cost of the transport and the loss of time in transit. For many too, the stress factor of joining a peak time commute, with its delays, cancellations, tail backs and crowding, must be factored in too.

It is fair to conclude then that the longer and more expensive the commute, the more difficult the justification of having a ‘town and country’ lifestyle is. Add to that assessment the environmental justification of all that high-speed day in and day out travelling and one might conclude that Cityvision ideas might be most receptively received in the commuter belt.

Building on opportunities

In the previous chapter on Cityvision we discussed how teleworking should be used, not to condemn people to work from home on the dining room table (unless they wanted to of course), but that it should provide them with the choice of when to ‘travel up to town’ and when it is just more productive to get the work done at or closer to home. The economic arguments against this though were tough to break down. A company would never contemplate maintaining a city-based office and then renting space all over the commuter hinterland for their employees to work from. Employees were no more likely to afford a rented working space either. Then in the later 1990’s BBM hit on the idea of rail season tickets being made flexible such that it could be used for both rail travel or to work in a brilliantly appointed shared workspace at the station. That was what BBM coined a ‘Comstation’.

Going back to the London to Brighton commute, let us look at how much that actually costs the commuter. In November 2014 that was a whopping £3,972.00.

Either a train operating company who might lease the land at the station could do it or Network Rail themselves. They could also get a company that specialises in the serviced office sector to do it for them. Either way, with this opportunity of using a season ticket cost to help pay for the facility and its management, there is a very workable potential there to exploit.

trains
Above: The main investment issue faced by both Network Rail and the train operating companies is planning for continuing projected increases in passenger demand over the foreseeable decades and this after a range of long term capacity improvements have already been implemented. Image: © BBM Sustainable Design Ltd.

What incentive though would the train operator have to introduce a Comstation? The answer to that lies in the Comstation helping to release peak time pressures which the train operators and Network Rail are constantly battling to attain. It is a technical and management headache that requires huge annual investment. In practice it is catered for by extra trains in the schedule, longer trains with more carrying capacity, super tight and very delicate timetabling and of course carrot and stick pricing structures to encourage off peak travel through differentiated ticket pricing. The slightest glitch to a service can throw a whole morning’s schedule off and when severe enough this leads to customer compensation. Then there is the consideration that rail travel projections are continuing to show increasing demand for the foreseeable future. The Long Term Passenger Rolling Stock Strategy for the Rail Industry, published in February 2013 states that, “The work done to date indicates that the national fleet size could grow by between 53% and 99% over the next 30 years”.¹

How that demand is met will require yet more major investment in the infrastructure with the technical solutions for doing so in some cases not even properly contemplated.

BBM envisaged that Comstations would be built at the stations but more specifically over the car parks used by the commuters. The fact that so many rail stations have large car parks is a boon and it is an asset with an interesting storey behind it. When containerised transport was introduced after the Second World War, the rail companies saw an opportunity to bring shipping containers into town centres by rail. These large tracts of land were set aside for marshalling the containers. What of course happened though is that road haulage took the business and, to accommodate the explosion of car use after the war, the land was instead turned into car parks for commuters. The car parks of course do create a revenue for the train operating or rail companies so the Comstation ought not to significantly reduce the parking capacity. For this reason the workspaces would be raised above the car parks.

How to build Comstations

Loading Bay 3
Above: Comstations could be pre-fabricated at railheads and transported to site on low loader wagons and craned rapidly onto a modular structure allowing the accommodation to straddle the station car park. Image: © BBM Sustainable Design Ltd.

It seemed sensible that with potentially hundreds of these Comstations to build, opportunities for devising a cost saving repeatable, modular and pre-fabricated system ought to be explored. Firstly, if production could be centralised, then real efficiencies in cost of production could be exploited. Such a place of manufacture could be located near a railway so that the delivery of the components could be by rail as well. Secondly, as car parking spaces are modular and that prefabrication and rail car sizes would benefit from a regularised size for production and transport, then it would make perfect sense to adopt a modular construction principle. Finally, by pre-fabricating the components, time on site could be greatly reduced which would be an important consideration for a busy station where ensuring total safety and minimising service disruption are paramount concerns.

Who would run Comstations and how would it be financed?

Among the plethora of essential components needed for getting a project like Comstation off the ground will be finding the right organisations to pay for and run the concern. We have already discussed that it might be the train operating companies who need to be brought on board to offer season ticket holders the ability to offer use of a remote working hub. However, it does necessarily follow that they should be the company that runs the facility or in deed owns the facility.

Network Rail actually owns virtually all the stations up down the country but they do lease out some of the stations to the rail operators.² So maybe it is Network Rail who would actually contract these facilities to be built. Comstations after all would become part of the railway infrastructure and Network Rail are a publicly owned company who maintain the rail infrastructure on behalf of the individual and privately owned train operating companies.

Could Comstations be conceived of like the rolling stock that the train companies run? Train operators actually lease the rolling stock from rolling stock leasing companies like Angel Trains, Eversholt Rail Group and Porterbrook Leasing.³ This would then require Network Rail and/or the lessee of the station to provide permission to build the Comstation on the station land.

Then there is the issue of getting the right team in place who understand the serviced office space market and could best plan and maintain the provision of that service. Companies like Regus specialise in this field and already run a large network of ‘ready-to-go’ office spaces in a number of locations around the UK and abroad. In fact, in 2001, BBM were actively pursuing an initial pilot project with Regus that was sadly curtailed by the terrorist attack on the New York World Trade Centre where Regus actually had setup a serviced office provision.

Taking Comstation forward

To get a Comstation network off the ground will need a massive campaign to win over hearts and minds in many different quarters as well as continue the concept design work. The financial models need to be explored as well as the technical design of a modular, repeatable and prefabricated design. Once a defined package can be illustrated, a wide ranging market analysis would be needed to test the potential for take-up. With the complexity of station property ownership and responsibility, Comstation projects would need all of the relevant stakeholders to be pulling on the same end of the rope. It would certainly help to lobby for political support to help drive that momentum.

As earlier discussed, the environmental and economic incentive for this to happen should be there and the drivers of that imperative essentially revolve around coping with existing and projected rail use. The Government should be interested because of the legally binding carbon reduction targets of 2050 and that Comstations would be a much easier political sell in the interests of curbing transport emissions than raising yet more fuel duty or carbon taxes.

BBM’s work on Comstation continued through the first decade of the Twenty-First Century as project briefs set for students of architecture where BBM maintained teaching links. In 2007, Duncan Baker-Brown and Ian McKay folded the Comstation idea into an even more ambitious investigation into the sustainable built environment with the Unplugged Studio. The objective of the studio looked at sustaining systems along the lines of the Transition Town principles and the ramifications of ‘unplugging’ from an oil-based culture and moving towards a circular economy. Harking back to ideas started with Cityvision, it was a holistic study of how the built environment functions and what architectural and infrastructure responses are needed to support a society that lives within the ‘carrying capacity’ of the Earth’s ecosystem. The Unplugged ideas are the subject of the next chapter.

Cityvision: Why Commute When You Can Telework Instead?

Introduction

Back in the early 1990’s there was a graph which depicted energy use by sector which clearly showed how over time the UK’s energy use in the transport sector was steadily overtaking those of industry and domestic energy use. It begged the question, if transport is going to be the biggest energy use culprit in society then what measures can we take in the built environment to remove the need, if not the want, to be so mobile? That in a nutshell was the point of departure for a project BBM nicknamed, ‘Cityvision’. By the mid-1990’s, BBM were disseminating ideas to see if society was ready to start reducing energy demand and pollution but also improving quality of life. These were ideas where buildings and urban structure played a major role in supporting lower energy lifestyles.


cityvision energy consumptionAbove: A very telling government graph discovered by BBM in the mid-1990’s depicted energy use by sector in the UK and clearly showed that the transport sector had grown from being the third biggest user to the biggest user of energy sometime around the late 1990’s as other sectors were reducing or stabilising. Source: DETR.

By the mid-1990’s it was clear that the growth of information technology and the arrival of the information age was going to play a big part in determining the cultural and economic direction of our future society. Surely then it made sense from an energy efficiency point of view to move information around instead of people? This can be illustrated by a simple carbon calculation of a passenger’s train trip from Brighton to London:

This is the paradox, why expend (in this case) 2700kg of carbon per annum in simply getting an employee to a computer to do the work from? Yes, there is fear of isolation from the employee and fear of losing management control by the employer but such concerns can be addressed.

So Cityvision was generated within the practice as a vehicle for researching the wider implications of information technology on the built and natural environments with a view to achieving a sustainable society. The study revealed that there was enormous potential for I.T. to help reinhabit the city. This was a time when the 19th Century infrastructure of British towns and cities was creaking under the influx of car based transport and out of town retail and office parks were springing up at an alarming rate. Even by the mid-1980’s it was becoming clear that traditional town centres were economically struggling and inner city life was becoming congested, unhealthy and undesirable.

In more recent years, with London becoming such a successful magnet for business, Cityvision ideas may well play a part in addressing some of the intense transport and real estate stresses the capitol’s insatiable metabolism is causing. People would have more freedom to live outside of London, still work for business based there and not having to commute every working day. Of course much of the economic unlocking of the potential would lie with rail companies offering flexible train tickets to compensate for the days not travelled on season passes but their incentive would be a pronounced reduction in the demand for peak time travel – a good thing all round.

Creating a Hypothesis

When Cityvision was initiated, information technology was being used predominantly by large corporations to effect only the most obvious money saving efficiencies which either condemned people to work in isolated home working conditions or in architecturally vacuous ‘telesheds’ built outside of traditional town centres and reliant on car based transport. Warning of these problems, BBM’s study then produced a range of measures that aimed to redirect this technology for more socially and ecologically beneficial results.

The central thesis of the Cityvision study is that everyday commuting can be substituted by flexible working both in terms of time and place.

cityvision typologies

The Cityvision hypothetical premise was that thirty years hence, thirty per cent of the population might be teleworking to some extent and under such conditions what implications would that have on the built environment? To demonstrate the potential, a slice of London drawn from the business district out to a commuting suburb was used to demonstrate the changes to urban / suburban form. In the city, the major change would be a less pronounced ‘rush hour’, less congestion at street level and more office space changed into housing. In the inner city suburb, where population densities could support them, ‘community workstations’ would spring up to offer a supportive place to work remotely from the traditional office and where diminutive dwelling sizes would preclude the setting up of a satisfactory home working environment. In the outer suburb, purpose made or refurbished teleworking homes might turn dormitory neighbourhoods into tight knit local working networks, in turn stimulating fresh economic activity into ailing local centres.

The ideas of Cityvision were not just about reducing energy use. The project also took the opportunity to address the social and mental stresses involved on the individual and the family in supporting an overt commuting lifestyle. It was plain to see that with two working parents with demanding and long commutes that it left the family unit potentially less cohesive and the children more vulnerable to unwanted influences. How valuable then it would be if some of those lost hours spent on the train, tube, bus or in the car could be grabbed back? So part of the Cityvision idea was to find a better live/work balance as well.

Interestingly, at the time of BBM’s Futurehouse, which opened to the public at a Milton Keynes housing expo in 1994, and boasted a dedicated home working office, it became clear that social isolation seemed to be a real concern for people. Many could not see how they could use their home to work from, citing insufficient space, family distractions or simply that there was no substitution for face to face discussions. In fact during the soundings that BBM took at Futurehouse we discovered that it was only the visiting journalists, who already practiced a high degree of home working that could completely see the potential.

The Futurehouse experience suggested that a more plausible basis for teleworking was not to take it to an extreme of a home working prison but to allow people the means to chose where and when is best for them, their families and their employers to do the work. Some days they would make the commute, for instance for all important team discussions and project reviews and other times, when for instance they need to ‘get their head down’, they might well be better off working from home.

The community workstation idea was worthy of further exploration as effectively a new building type. It would be a fusion of open plan and cellular office spaces, meeting rooms (all for rent by the individual), a community centre, crèche and café. Ideas for the inclusion of a pocket gym were also part of an exciting mix of facilities to support a busy and congested urban life all contained within a single time saving wrapping. The facility might best be pursued as a public building with a range of revenue generating concessions, such as the gym, crèche and café.

BBM approached a number of London boroughs with the Cityvision ideas in the mid to late 1990’s with a specific goal of getting a community workstation built. The London Borough of Greenwich was sufficiently interested to fold-in some of the ingredients into a telematics training hub. After an initial study to look at some possible sites within the Council’s property portfolio, it was decided to refurbish a Napoleonic era building within the former Woolwich Arsenal and as such it would become the first part of a much wider regeneration of the Arsenal site. The Woolwich Teleservices Centre, as it became known, had as its main directive to provide I.T. training to local people (from areas of quite pronounced socio-economic deprivation) with a view to improving job prospects.

The work on the Woolwich Teleservices Centre was partly why BBM were invited to work on the Greenwich Millennium Village where their vision for future working and environmentally benign lifestyles formed part of the competition winning entry. BBM, working alongside HTA Associates and veteran urban masterplanner, Ralph Erskine suggested a ‘Teleservices Centre’ (essentially the original community workstation idea rebranded) be adopted as the focus of the entire development and was to be accommodated at the centre of the main public space within the proposals. Regrettably without an organisation to run the facility, the Teleservices Centre remained an idea.

Twenty years on, or two-thirds the way through the Cityvision thirty year hypothesis, the information age has made home working and flexible working a reality for many. In 1994 only a few universities and large multi-nationals had teleconference facilities but in the last decade we have seen the introduction of Skype and FaceTime bringing video calls to people’s computers and smartphones. The arrival of the chain coffee shops in the 1990’s capitalised on the mobile working potentials of laptops and mobile phones which they supported through the provision of Wi-Fi connectivity, carefully designed seating and cleverly tuned acoustics. The result has seen the working environment being extended into a café setting but instead of the worker paying rent for a space, it is the consumer buying the right to sit down through the purchase of coffees and snacks.

In recent years one particular subset of ideas out of Cityvision seems to be gaining traction in the commercial sector, that of a combined rentable office space and crèche. In particular it is mothers looking to get back into work, who could do with being close to their children and not having to spend unnecessary time enduring a daily commute, who have really taken up the idea. Third Door in southwest London started in 2010 around the same time as Brighton’s Officreche. Both are private ventures and both provide comfortable flexible office space and meeting rooms in combination with superb childcare facilities. In the case of Officreche the location is also within about five minutes walk of Brighton Station. Third Door is now opening a second location.

Perhaps there is a small percentage of people now teleworking some of the time but in places like London, the Cityvision effect is negligible in terms of reducing demands on the infrastructure and real estate. London is one of a handful of global cities which is experiencing a phenomena where success breeds more success and seemingly all young and ambitious professionals feel they ought to live and work there. It is a trend that has been coined, “agglomeration economics”. London however is at risk of sinking under its own unaffordable accommodation bubble with young people are unable to get a foothold on its property ladder either through buying or renting and where many workers who provide key services are simply moving out for a less congested and less financially stressed life. It is not hard to see how aspects of teleworking could help.

Comstation; The Saviour of the Commuter Belt?

In the late 1990’s, BBM realised that although on paper it should be possible to make a business case for setting up community workstations in the inner city areas of the major conurbations, the target market for teleworkers might be most helpfully exploited in the commuter belt towns. If the train operators could also be brought in to provide these remote working platforms as part of their service offering, many of the commuters or employer’s financial reservations about adopting modes of teleworking should melt away. BBM’s next evolutionary idea from Cityvision which met these very particular constraints and opportunities was coined ‘Comstation’ and is the subject of the next chapter.
