House Extensions

Single and double-storey extensions that add real space, light and value to your home.

What's Involved

House Extensions, done properly

An extension is the difference between loving your home and outgrowing it. We build single-storey, double-storey, side-return and wrap-around extensions that open your home up and let the light in.

We take care of the whole build, working to approved plans and your engineer's spec, and tie the new space seamlessly into the old. The result feels like part of the original house, only better.

What's Included

Everything under one roof

One team covers the whole job, so the trades work together instead of pointing fingers. Here is what a typical project with us usually covers.

01

Single-storey extensions

Kitchen-diners, family rooms and garden-facing spaces.

02

Double-storey extensions

Extra living space below and a bedroom or bathroom above.

03

Side-return & wrap-around

Making the most of that unused strip down the side.

04

Kitchen extensions

Open-plan spaces built around how you actually live.

05

Bi-folds, skylights & glazing

Bringing daylight deep into the new room.

06

Steelwork & foundations

Solid structure below, clean finishes above.

How It Works

A clear path from first visit to final finish

No surprises and no disappearing acts. You always know who is coming, what is happening next and roughly how long it will take.

01

First visit & quote

We come out, look at the job properly and talk through what you have in mind. You get a clear, written quote with no pressure to go ahead.

02

Drawings & approvals

Where a project needs plans, building control or party-wall agreements, we help you get everything in order before work starts.

03

The build

Our own team carries out the work, keeps the site tidy and protects the rest of your home the whole way through.

04

Finishes & second fix

Plastering, tiling, joinery, decorating and the small details that turn a building site back into a home.

05

Final walk-round

We go through the finished work with you and only call it done when you are genuinely happy.

Good To Know

Questions we get a lot

How much does an extension cost?

It depends on size, ground conditions and finish. After a visit we give a clear written quote, so you know the figure before committing.

Do you work from architect's drawings?

Yes. We build to your architect and structural engineer's plans, and can recommend people we trust if you do not have them yet.

Can we stay in the house during the work?

In most cases, yes. We seal off the work area, keep things tidy and plan the disruptive stages with you.
