Every line on the page, built to the millimetre.

Our approach

One team draws it, builds it and hands you the keys. No passing the problem down the line. Just the room, done properly.

Recent work

Built, not bolted on.

Extensions that feel like they were always part of the house. Steel, glass, timber and brick, chosen for the street they sit on.

Stage01

Survey & drawing

We measure the house, talk through how you live, and draw the room before a single brick is ordered.

Stage02

Planning & structure

Planning, party wall notices and structural calcs, handled for you and explained in plain words.

Stage03

The build

One site lead from groundworks to plaster. A weekly walk round so you always know where things stand.

Stage04

Handover

Snagged, cleaned and signed off. You get the keys to a finished room, not a list of jobs.
