Chetwood Associates is to spend a £40,000 competition prize on exploring how sustainable design can have a positive impact on the bottom line. Last week Chetwood's supermarket design for J Sainsbury in Greenwich, south-east London, won the 'Design Sense Award' competition run by the Design Museum, beating entries from a dozen other shortlisted architects and manufacturers.
Its supermarket, built on a brownfield site near the Millennium Dome, makes maximum use of natural light and requires half the power of a standard supermarket. The design uses recycled materials such as aircraft tyres for the floor matting and plastic bottles for splashbacks in the WCs and it has a combined on-site heating and power plant.
Chetwood Associates' director Paul Hinkin said: 'This store has achieved the highest satisfaction rating for any Sainsbury's. We want to measure the effect low-energy building design has on both staff and customers to prove the commercial benefits to wider industry.'
A statement from the Design Museum said the supermarket 'sets a new benchmark standard for building design in the retail industry'.
Design Museum director Alice Rawsthorn said she was proud to promote sustainable design 'as an antidote to Changing Rooms culture'.
