Nutwood Steading is a project for the conversion of a historic coach house and stable to a sustainable family home. The brief was to retain and upgrade the existing buildings creating a spacious and modern, energy-efficient family home while remaining the sensitive to beautiful historic buildings and their setting. It was important the design used a low embodied carbon approach to material selection and have a high energy performance. The client required the site to be fossil fuel-free, requiring a biomass boiler for primary heating. Whilst still connected to the grid, Photovoltaic (solar) panels on the south-facing roofs were used to create on-site energy.
