Questions people ask
Which rear extension is right for my house?
It depends on what the house lacks: a bigger kitchen suggests single-storey, missing bedrooms suggest two-storey, and a narrow galley kitchen on a terrace suggests a side return or wraparound.
Do you do side extensions or loft conversions?
We specialise in the back of the house. Side returns and wraparounds are included because they are built with the rear.
Do you design as well as build?
Yes. Survey, drawings, planning route, Building Regulations and the build are all part of the service.
