Home Extensions in Bramhall
Bramhall plots tend to be generous at the rear and tight at the side. That shapes what makes sense — and we would rather design the extension that suits your plot than sell you the one that suits our diary.
In short
Single-storey rear extensions in Bramhall generally cost £2,200–£3,000 per square metre for a quality finish, with double-storey work from £1,800–£2,400 per square metre. A typical project takes 10–16 weeks on site. Greenbank manages design, planning, structural engineering and the build, and responds within 48 hours to book a free site visit.
Local knowledge
Home Extensions in Bramhall — what the housing stock demands.
Bramhall's inter-war and post-war housing generally sits on plots with real depth behind the building line, which is why the rear kitchen-diner extension is by far the most common project we build here. Side returns are more constrained — many streets have narrow gaps between properties, and drainage runs frequently sit exactly where the new foundations want to go.
Typical Bramhall projects
- 1930s semis — single-storey rear extension opening the kitchen into a family dining space.
- Detached homes off Bramhall Lane — double-storey rear extensions adding a bedroom above living space.
- Bungalows around Kitts Moss — side and rear extensions with roof-lights to bring light deep into the plan.
- Properties backing onto mature trees — root protection and deeper or piled foundations need pricing honestly at survey stage.
Planning & Building Regulations
Many single-storey rear extensions in Bramhall fall under permitted development or the larger home extension prior approval route. Double-storey work almost always needs full planning permission from Stockport Council, plus a Party Wall agreement where you build up to a boundary. We handle all of it.

How we build it
The detail that decides whether it lasts.
Trees and foundations
A lot of Bramhall gardens have mature trees, and clay subsoil south of the Mersey reacts to them. That can mean deeper foundations or a piled solution. We establish this with a trial hole before quoting rather than pricing standard trench fill and issuing a variation once the digger is on site.
Drainage is rarely where the plans say
Older Bramhall properties frequently have shared or diverted foul runs that do not match the utility records. We survey and, where needed, price the diversion up front. It is the single most common cause of cost creep on extensions in this area.
Light, not just floor area
An extension that doubles your kitchen but darkens the original rear rooms is a poor trade. We design with roof-lights, structural openings and glazing positions chosen for how the space will actually feel in February, not just how it renders in a brochure.
