Extensions in and around Nelson
Across BB8, BB9, we can visit, measure and advise. The same team covers Colne (2 miles), Burnley (3 miles), Accrington (8 miles), Rawtenstall (10 miles), all within easy reach.
For homes towards West Yorkshire, Keighley is around 12 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.
Do I need planning permission in Nelson?
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
The planning position for a specific Nelson address depends on its history and any designations, which is why we check it at the first visit.
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.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
We visit your Nelson home, measure up, talk through what you want and check the planning position.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Your questions about a bungalow extension in Nelson
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Nelson, 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 bungalow extension take to build in Nelson?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do I need building regulations approval in Nelson?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,660 to £3,230 per m² including VAT. Going upwards is priced after a structural survey.
