What we do

Your extension, and what comes with it

We take on renovation work as part of an extension project, not on its own.

The main event

Your extension

Single and two-storey extensions, 50 m² and over, designed for SIPs or timber frame from the start.

While we're there

Renovation

Repair and renewal of the existing house, carried out alongside the extension.

While we're there

Remodelling

New layouts, openings and structural changes so the old and new work as one home.

While we're there

Low energy upgrades

Insulation, airtightness, windows and ventilation in the existing house, done with the extension.

Why us for your extension

Frame makers make great frames. We build the whole extension.

A frame supplier's service covers the frame. A traditional builder may not have built with SIPs or timber frame before. We do both: the system, and the construction around it.
