Working in Rawtenstall
Our survey diary covers Rawtenstall, including BB4. We also work in nearby Accrington (5 miles), Burnley (7 miles), Darwen (7 miles), Blackburn (9 miles).
For homes towards Greater Manchester, Bury is around 7 miles away. Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.
Planning and approvals in Rawtenstall
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.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
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).

Questions people ask about pitched roof extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Rawtenstall, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does a pitched roof extension take to build in Rawtenstall?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do I need building regulations approval in Rawtenstall?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Is a pitched roof better than a flat roof?
Neither is better in all cases. Pitched roofs blend with traditional houses and shed water quickly; flat roofs give more headroom and suit modern designs and lanterns.
How much does a pitched roof extension cost?
Our guide range is about £1,760 to £3,320 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
