Home extensions in Cheshire
Rear, side, wraparound, double-storey and loft. We design, get the planning or permitted-development paperwork sorted, build it with our own team and hand back a finished room, not a shell.
What's included
- Measured survey, drawings and structural engineer's calculations
- Planning application or lawful development certificate, and building regulations sign-off
- Groundworks, drainage, masonry, steels and roof
- Windows, bifold or sliding doors, roof lights
- First and second fix electrics and plumbing, underfloor heating where wanted
- Plastering, decoration, flooring and external making-good
- One fixed price, one project manager, a written programme before we start
Typical timeline
A single-storey rear extension takes 10 to 14 weeks on site. Double-storey, 14 to 20 weeks. Add 8 to 12 weeks beforehand for drawings and planning if a full application is needed; many rear extensions fall under permitted development and can start sooner.
Planning in Cheshire
Under permitted development a detached house can extend 4 m to the rear (8 m with prior approval); a semi or terrace 3 m (6 m with prior approval). Conservation areas in places like Knutsford, Nantwich and parts of Chester tighten this, and Cheshire West & Chester and Cheshire East each run their own prior-approval process. We handle it.
Why owners choose us
We build extensions on our own development properties, so every detail is priced and sequenced the way a developer would do it: no padding, no surprise variations, and a programme we actually keep to.
