Every now and then BBM take on small design projects like this garden studio and potting shed. The Lewes based clients are delighted with the results and are enjoying their own design and build project as they integrate its new garden setting. It is less garden shed but more mini-building with a high performance thermal envelope that exceeds the energy efficiency requirements of the Building Regulations. Working closely with the clients, BBM carefully profiled the design to the steep cross-fall on the site so that its appearance sits neatly into its garden setting.

The larger room of the building aimed to provide a dramatic high space that is used by the couple as a painting studio. It has a mix of north and south facing skylights and a large sliding patio door looking back over the garden towards the house. Its southern end, over the worktop counter, has a very low eaves height to minimise the building’s overall volume externally. The building steps down to the small potting shed on the south side where two large skylights afford ideal growing conditions for seedlings. Neatly tucked around the side of the building are two wall hugging rainwater butts for watering the garden.

BBM were appointed for the design stages only and completed their involvement by providing the clients with a ‘design intent’ package of work. This fully described the way in which the building should be built and detailed. The builder, Chalmers and Co. executed the project directly with the clients who were very impressed with their results.
