Bungalow rear extension in Spalding

Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Spalding and the surrounding area, with one contract from the first survey to building control sign-off.

We cover Spalding (PE11) as part of our Lincolnshire work. For Spalding bungalows we design the roof first, because the low eaves decide the height of the new room.

Bungalow rear extension prices in Spalding
SizeGuide price inc VAT
3 m wide × 4 m deep (12 m²)£21,500–£35,000
4 m wide × 6 m deep (24 m²)£43,000–£70,000

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

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

Whether your bungalow rear extension in Spalding needs a planning application depends on its size, your house and any local restrictions.

In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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 Spalding like to extend?

Spalding has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

FAQ

Bungalow rear extension questions in Spalding

How much does a bungalow rear extension cost in Spalding?

As a guide, £1,790–£2,910 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £21,500–£35,000 at that rate. Your written price follows the survey.

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.

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.

Do you handle building control in Spalding?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

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

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