Local to Bolton
We cover Bolton and the postcode districts BL1, BL2, BL3, BL4, BL7, M38. The same team covers Farnworth (3 miles), Westhoughton (4 miles), Radcliffe (5 miles), Atherton (5 miles), all within easy reach.
For homes towards Lancashire, Darwen is around 8 miles away. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.
Planning and approvals in Bolton
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a home office extension in Bolton
Do you cover all of Bolton?
Yes. We cover Bolton and the surrounding parts of Greater Manchester. Site visits are free and there is no obligation.
Do I need building regulations approval in Bolton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Bolton, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Is an attached office better than a garden office?
An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
How much does a home office extension cost?
Our guide range is about £1,760 to £3,230 per m² including VAT. An 11 m² standard-spec office is typically £22,000 to £28,500 in Bolton.
