Two members of the forum, HTA Design LLP and BLP Insurance, have set up a joint venture to build a fully functioning comparison website. This will be able to match the Housing Forum sample of new and existing homes against the performance expected by the Mayor’s Standard and rank them according to the following range of measures: price, net floor area, cost per square meter/foot, storage area, volume, average daylight level, estimated annual energy costs, estimated annual maintenance costs and broadband speed. The website is designed as a module that can take the information normally presented by housing comparison sites such as Zoopla and RightMove and enhance it by enabling browsers to rank properties offered by the search engine according to their predicted performance. It also presents consumers with a traffic light indicator showing how homes rate in relation to established standards of design.
