The Chiswick Point development, at Bollo Lane, in West London, is a £20m contemporary mixed-use residential scheme offering 124 one, two and three bedroom residential apartments, including three penthouses. A sustainable approach was important, with all of the units designed to meet Level 4 of the Code for Sustainable Homes, and the Lifetime Homes code. Constructed in two blocks of six and nine storeys, the frame is mainly reinforced concrete, with the concrete frame floors and cladding providing thermal mass, which absorbs energy and slowly releases it to help reduce temperature fluctuations.
Long continuous ribbon balconies provide solar shading to the two blocks and provide the residents with a very pleasant outlook across the London Wildlife Trust nature reserve at the rear of the development. The continuous balconies are a major feature of the scheme and with several hundred metres of them winding across the two blocks, effective thermal insulation was imperative if thermal bridging is to be avoided. To minimise any condensation problems and subsequent mould growth as a result, plus the avoidance of thermal outflow, Schöck Isokorb® T type K heat-insulating load-bearing elements are installed at various strategic positions along the large expanse of balconies. The Schöck Isokorb® T type K provides high thermal resistance by using stainless steel bars to act as tension and shear reinforcement, plus high-strength HTE pressure bearing modules.
