Rear extensions for bungalows in Lincolnshire

Single-storey rear extensions that keep everything on one level. Across Lincolnshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Lincoln, Grimsby and Scunthorpe.

For Lincoln bungalows we design the roof first, because the low eaves decide the height of the new room. Lincolnshire has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

How much does a bungalow rear extension cost in Lincolnshire?

Guide prices for a bungalow rear extension in Lincolnshire start from our East Midlands rate of £1,790–£2,910 per square metre, including VAT. East Midlands prices sit a little below our West Midlands baseline.

4 m wide × 6 m deep (24 m²)£43,000–£70,000

We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.

Do you need planning permission in Lincolnshire?

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.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ

Questions people ask

Can a bungalow extension be fully accessible?

Yes: level thresholds, wider doors and a wet room are straightforward to design in.

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.

Can I extend the loft as well?

Sometimes, but that is a different project; a rear extension keeps everything on one level.

Do you cover all of Lincolnshire?

We cover 17 towns and districts in Lincolnshire, including Lincoln, Grimsby and Scunthorpe.

Who builds the extension?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
