Which extension suits your home?
Most homes suit one of four types. We'll tell you which on the first visit.
- Side view01
Single storey rear
The most popular choice. A bigger kitchen and family room that opens onto the garden.
Good for: Kitchens, open-plan - Side view02
Double storey
Room downstairs and up. Often the best value per square metre if you need bedrooms.
Good for: Bedrooms, en-suites - Plan view03
Side return
Uses the narrow alley beside terraced and semi-detached homes to widen the kitchen.
Good for: Terraces and semis - Plan view04
Wrap-around
Side and rear together in an L-shape. The biggest change to how the ground floor works.
Good for: Whole ground floor

What affects the cost?
Every extension is priced from its own drawings. These four things move the price most:
- 01Size, and whether it's one storey or two
- 02Glazing: bi-folds, roof lanterns and skylights
- 03Ground conditions and the foundations needed
- 04Kitchen, flooring and the level of finish
You get a fixed, itemised quote before any work starts.

Ask a questionMost single storey extensions take around 10 to 14 weeks on site, and double storey around 14 to 20. Drawings and approvals come first, and we plan that time with you.
Yes, in most cases. We build the new shell first and only open into the house near the end, so the time without a kitchen is kept short.
Not always. Many single storey rear extensions fall under permitted development. We check on the first visit and handle the application if you need one.
Yes. Drawings, structural calculations, planning and building control are all done by our team, so you have one point of contact.
Yes. Once the drawings are done you get a fixed, itemised quote. If you change something later, we price the change before doing it.
