The foundations will contain insulation, to reduce heat loss and minimise the use of concrete. The concrete will look to use alternatives to cement which is carbon heavy. Alternatively ground screws will be used to further reduce the need for concrete. Oriented Strand Board (OSB) can be used in the construction, and it will be treated with a water based and eco-friendly fire retardant, so at the end of their life they will be recyclable (normal fire retardant would render the panels unbiodegradable). Facades can be customised, finishing materials can be selected from a range of proposed sustainable materials: untreated wood cladding, shingles, cork panels or upcycled PVC.
