Bungalow rear extension in Nelson

We plan and build rear extensions for bungalows for homeowners in Nelson. Single-storey rear extensions that keep everything on one level. Start with a free site visit, then a written price once the design is agreed.

Nelson is covered from our Lancashire round, including BB8, BB9 and BB10. For Nelson bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Nelson?

Planning for a bungalow rear extension in Nelson follows the English householder rules.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Nelson like to extend?

Stone and brick terraces are common around Nelson. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

How a bungalow rear extension in Nelson comes together

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  2. Design and guide price

    Two or three layout options with a guide price for each, so you choose the design knowing what it costs.

  3. Approvals

    Permitted development check, prior approval or planning application, then Building Regulations drawings and structural calculations, plus party wall notices where they apply.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Bungalow rear extension questions in Nelson

Is the site visit in Nelson free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

How much does a bungalow rear extension cost in Nelson?

As a guide, £1,740–£2,820 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £21,000–£34,000 at that rate. Your written price follows the survey.

Will the roof look odd?

Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.

How long does a rear extension take to build in Nelson?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Do I need a party wall agreement?

In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.

Can you match the brick or stone on my Nelson house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
