Extensions

We coordinate and deliver extension projects that enhance both the function and character of a home.

Why Choose Us
Extension projects are approached as part of the wider building, with structure, layout, light and finish considered together from the outset.

Design & Integration

Every extension begins with the relationship between old and new.

From single-storey and two-storey extensions to orangeries, porches and oak-frame additions, each project is shaped around the existing home, its proportions and how the new space will be used.

Connection to the Existing Home

An extension does more than create new space. It changes how the existing home works, feels and connects.

We consider how rooms move, open and relate to one another, creating layouts that support modern living while maintaining a calm and coherent overall feel.

From Structure to Finish

Extensions are carried through from the underlying build to fully resolved interiors, finishes and detailing.

This ensures continuity of quality and intent throughout the project, so the finished space feels complete rather than simply added on.
