House Extension Builders in Somerset

We’ve been helping local homeowners transform their properties since 1987.
As one of the most established house extension companies in Somerset, we
bring over 35 years of experience to every brick we lay.

Whether you’re looking for a rear, wrap-around, or multi story extension to expand your living space and add value to your home – our local team of Building Craftsmen can helpp.

Our orangery and conservatory extensions are designed with solid masonry and high-spec roofing to ensure they are thermally efficientin winter and cool in summer.

We build architectural-grade garden rooms that are fully insulated, wired for power and data, and built to the same exacting standards as a primary residence.

A rear extension is a popular choice for opening up the back of your home. It’s an ideal way to create a larger, more social living area or a spacious kitchen-diner.

When you need a significant amount of extra room, a two-storey extension is often the most effective solution, allowing you to build on both levels.

This is the ultimate transformational house extension, allowing for entirely new layouts, utility rooms, and ground-floor kitchen and shower rooms.

We work closely with kitchen designers and architects to ensure the skeleton of your extension is perfectly placed for your new kitchen and dining layout.
