Retrofit and Extension, Guildford
A 1930’s detached house, of cavity and solid wall construction was extended to provide an additional bedroom, new kitchen, and spacious family room overlooking the garden.
The existing house was insulated and upgraded, resulting in typical U values of 0.15 W/m²K.
New triple glazed windows were installed.
Energy calculations were carried out using Passivhaus software, the eco refurbishment was based on EnerPhit principles.
