The new Homes for Neighbourhoods Programme was launched by Brighton and Hove City Council to test small sites within the Council’s portfolio of land. BHCC asked the RIBA to manage an open design competition. The brief included four sites each with problematic physical constraints and designed to fit within cost parameters of £1,700.00 per sq. m. Each entrant had to submit solutions for two of the four sites.

The Frederick Street site was selected by BBM as it was representative of a dense central Brighton urban context and was challenged by being effectively a single aspect site with very tight access restrictions.

For both schemes, BBM worked with a local specialist in the supply of volumetric modular construction. The cold formed steel structural modules are fabricated off-site (fully finished internally) and brought to site where they can be craned into position, combined and then clad to form single storey or multi-storey buildings. This technique has the advantage of reducing site construction waste, erection times, defects and cost over that of conventional forms of construction.

Minimising the number of site deliveries and erection times was particularly important for the Frederick Street site with its central Brighton location.

The designs of the flats incorporated Lifetime Home Standards, bin, buggy and bike storage and electric car charging bays for urban car club vehicles. The designs were also analysed for energy efficiency through the Passivhaus Planning Package, indicating that energy use within the dwellings could be as low as 7 kWh/(m2a).

BBM’s interest in utilising waste and locally sourced minimally processed materials in construction identified an opportunity to use ‘clunch’ chalk, flint and brick rubble laid dry within shallow gabian cages as a form of dry stone rainscreen cladding. The aesthetic created would draw a natural link to the famous Brighton vernacular known as ‘bungaroosh’.
