Home / House Extensions Durham
More space without the move. Single and two-storey extensions across Durham, designed and built by one accountable firm, design through handover.

Outgrown your home but love where you live? An extension adds the space, value and function you need without the cost and upheaval of moving. We design and build extensions right across Durham, on everything from the Victorian terraces to the newer estates around Newton Hall and Belmont.
We run the whole job: design, planning, structural work, every trade and the finishes. One contractor, one programme, one fixed price, so you're not coordinating an architect, a builder, a sparky and a plumber who've never met.
A named Contracts Manager keeps it on track with daily site visits, and you get a written programme before a brick is laid.
The people on your job work for ATKINSONS. One firm accountable for the lot.
A named Contracts Manager from first visit to final certificate.
Real people answer, day or night. Engineers dispatched, not job numbers logged.
In writing, in plain English. No surprises in the small print.
It depends on size, specification and ground conditions, so we don't guess. We visit your Durham home, measure up, and come back with a fixed written quote in plain English. The free site visit carries no obligation.
Not always. Many single-storey extensions fall under permitted development, but conservation areas and listed buildings around the city have tighter rules. We assess this at the site visit and handle any application to Durham County Council.
A typical single-storey extension runs eight to twelve weeks on site depending on size and spec. You get a written programme before we lay a brick.
Usually yes. We phase the work to keep your home liveable, and a clean, tidy site is part of how we work.
Yes, all of it: design, structural calculations, planning where needed, building control sign-off and completion certificates, under one contract.
A named Contracts Manager from day one, on site daily, reachable throughout. One person accountable from first visit to handover.
No. Every trade on your Durham extension is on our own books, which is why one firm stays accountable for the whole job.
