Single and two storey extensions are the most common type of home improvement to provide additional space or an additional room/rooms.

Often extending your property can be more cost effective than moving house. We have provided Building Control services on thousands of domestic extensions and are able to advise on the typical problems which you may encounter prior to commencing your project.
