Hutton Mount
A single-storey rear extension to a detached house on Hutton Mount in Brentwood, completed in 2025. The client wanted a bigger kitchen and dining space opening onto the garden.
We built the extension in blockwork with a flat roof and two rooflights, then took out the back wall of the house so the existing room and the extension became one open-plan kitchen-diner. The wall above was propped and needled while the opening was formed and the new steels went in. We then fitted out the room, including the kitchen.
Groundworks to fit-out
We ran every stage on site: foundations and slab, blockwork walls, the flat roof and rooflights, propping the back wall and putting in the new steels, then insulation, services, plastering, flooring and the kitchen fit-out.
One point of contact
The extension was built to the client's design and signed off by building control on completion. Lough Build managed the work on site from the first trench to the finished kitchen, and the client had one point of contact throughout.

Opening up the back wall
To join the extension to the house we took out the back wall. The wall above was propped and needled while the opening was formed and the new steels went in, so the house stayed supported throughout. The existing room and the extension now work as one open-plan kitchen-diner.
