House Extensions

Single and double storey extensions, wrap-arounds and loft conversions that feel original to the house.

House Extensions

The test of a good extension is that it does not read as an extension. Getting there means matching brick and mortar properly, running floor levels through, and resolving the junction between old and new so the roofline and eaves sit right.

We deliver rear and side extensions, wrap-arounds, double storey additions, loft conversions and garage conversions, including the party wall process and building control throughout.

Living through the work

Most extension clients stay in the house. We build a temporary separation, keep the kitchen running as long as we possibly can, and sequence the noisy work into agreed windows.

  • Loft and garage conversions with building control sign-off
  • Party wall notices and surveyor liaison handled for you

Common Questions

Many single storey rear extensions fall under permitted development, but limits vary by property and location. We will tell you honestly at the first visit which route applies.

On a typical rear extension, around three to four weeks. We plan the sequence with you and can install a temporary kitchen if needed.
