Whole house strategy

The Lower Royd radical retrofit is a ‘whole house’ refurbishment of a Yorkshire farmhouse and barn. The project employs  a whole house strategy similar to our previous Cumberworth radical retrofit project, but with more of  blank canvas  as the building  has effectively  been gutted. As at the Cumberworth project, the project is working towards CarbonLite retrofit standard.
