How we work

From the first visit to the final handover, you deal with one team, and we're there on site.

  1. Site visit and quote

    We come and look at the house, talk through what you want, and give you a free written quote.

  2. Drawings

    Your architect and engineer draw up the plans. We build to their drawings and work with them through the job.

  3. Planning and Building Control

    Once you've arranged the planning, we take the reins and book the Building Control inspections as the project progresses.

  4. The build

    Our dedicated team is on site, and you have one person to call. We keep you updated as each stage is done.

  5. Handover

    We finish, clear up, walk round the job with you, and make sure you get the Building Control completion certificate. You'll need it when you sell.

Questions about extensions

Do I need planning permission?

Not always. Many single-storey rear extensions fall under permitted development. You arrange any planning that's needed, usually through your architect, and once it's in place we take the reins.

Can you build to my architect's drawings?

Yes. We build to your architect's and engineer's drawings and work with them through the job.

How long will it take?

It depends on the size of the extension and the house. Your quote comes with a programme, so you know what to expect week by week.
