This Georgian farmhouse in Sevenoaks had received planning permission for a 2 storey extension to be built using sustainable straw and timber panels. Claire developed the planning scheme into a full set of construction information, liaising with the panel manufacturer and the build team to coordinate the design. Modular timber panels prefabricated with straw infill provide both structure and insulation. The exterior is clad in sweet chestnut timber and topped with an oxidised copper roof, the interior is finished with lime render. Natural materials create a sustainable build as well as providing a healthy and comfortable internal environment.
