We designed and delivered an interactive class room for the Land Trust which appears to float over a lake at Greenwich Peninsula Ecology Park. A dipping jetty oversailing the lake can be used by visiting children to explore the wildlife at this popular ecology park. Our role spanned across all work stages from initial design proposals through the planning stage, tender process and contract administration. The innovative construction method borrowed ideas from WikiHouse, an innovative open-source construction technique. This allowed the building components to be delivered to this restrictive site and erected quickly and easily.
