Is this right for you?
For people who love where they live, but need more of it.
If you've outgrown your house but love where you live, an extension is usually the better answer than moving. Maybe the kitchen's too small for how your family actually uses it, maybe you need a downstairs bedroom, or maybe you just want a bit of breathing room that doesn't exist yet.
We design extensions around how you actually live — not around a standard layout we've used a hundred times before. The result is a space that feels genuinely part of the house, not an afterthought tacked on the back.
What's included
The full job, under one roof.
We handle every part of your extension — from the first drawing to the final coat of paint — with one team and one point of contact throughout.
- Rear and side return extensions
- Wrap-around extensions
- Double-storey extensions
- Kitchen-diner extensions
- Structural work, including steels and load-bearing changes
- Full finish — plastering, electrics, plumbing, flooring, decoration
How we work
Calm, clear, from survey to handover.
We start with a free consultation and a proper site survey, so the design is based on your actual house — not a guess. From there, we draw up plans, handle the planning submission with the council, and manage Building Control on your behalf.
Once it's approved, the same team that designed it runs the build — including the groundworks, brickwork, carpentry and finishing trades — so you're never passed between companies partway through.
Free survey
We come to you, look at the site, and give you an honest view of what's possible.
Design & planning
We draw up the plans, submit to the council, and manage Building Control.
Build
The same team builds it — groundworks, brickwork, every trade through to the final finish.
Why Metro
One team. One number to call. One outcome to own.
A lot of extensions involve three separate relationships: an architect for the drawings, a builder for the work, and a string of trades the builder brings in that you've never met. If something doesn't line up — a measurement, a finish, a timeline — it's not always clear whose job it is to fix it.
With Metro, it's one team and one point of contact from your first phone call to the day we hand the keys back. There's always someone who owns the answer.
- Design, planning and build in one team
- No handoffs between companies
- One point of contact, start to finish
- Over 40 years' experience behind every project
Common questions
Extension questions, answered honestly.
Do I need planning permission for an extension?
Often not, if it falls under permitted development — but it depends on your property and area. We check this for you at the survey stage and handle the submission if it's needed.
How long does a home extension take?
It depends on size and scope. We'll give you a realistic schedule before work starts, and keep you updated if anything changes along the way.
Will I have one point of contact throughout?
Yes — the same team from your first consultation through to the final finish, not a different company at each stage.
Can you match the extension to our existing house?
Yes, that's the goal — we design extensions to sit naturally with your home's existing style and structure, not stand out from it.
Do you handle the structural work, like steels?
Yes, structural work is part of our in-house build — it's not subcontracted out and lost track of.
What if we want to extend and renovate the rest of the house at the same time?
That's common, and it's straightforward for us — see our Refurbishments page, or just tell us what you're planning and we'll scope it as one job.
