At Deepdale Avenue, Cohanim has been developing a substantial detached leisure building within the grounds of an existing house.
The pavilion brings together an indoor swimming pool, jacuzzi, sauna, gym, changing and bathroom accommodation with external terrace and veranda areas. What appears visually as a simple garden building is therefore technically closer to a small specialist leisure facility.
The architecture has progressed through planning-level design into a detailed Building Control package.
The principal challenge is the interaction between the pool environment and the site itself.
The building sits within a sloping landscaped garden and requires significant retaining construction, waterproofing and ground coordination. Internally, the warm and humid pool hall places unusually high demands on the envelope: vapour control, insulation, thermal bridging, rooflights, glazing, ventilation and condensate management all need to operate as one system.
The technical design also incorporates pool structure and tanking, plant and filtration, backwash and draindown, foul and surface-water drainage, specialist MEP, tree constraints and geotechnical considerations. The current Building Control review is coordinating these interfaces with structural, pool, M&E, drainage and arboricultural specialists.
It is a strong example of engineering-led residential architecture, where the success of the finished space depends upon resolving a large amount of technical complexity behind a comparatively restrained architectural expression.
