Extensions

Considered extensions that add light, volume and value — designed to sit naturally alongside the existing house rather than compete with it. Delivered for homes across Oxford and Oxfordshire.

Overview

Rear, side-return and wrap-around extensions that transform how a home lives.

We design and build rear, side-return, wrap-around and double-storey extensions across Oxford and Oxfordshire. Every scheme begins with the way you actually use your home: where the light falls, where the family gathers, and where the existing plan lets you down.

Our in-house design team handles surveys, planning drawings, permitted development assessments, party wall coordination and building control, so the project moves from sketch to structure without gaps between consultants.
