Rear extensions for terraced houses in Bedfordshire
Rear and side return extensions for terraces, with access through the house and two neighbours. We design and build rear extensions across Bedfordshire, from Luton and Bedford to Dunstable, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Terraced streets make up much of the housing in parts of Bedfordshire, and most rear extensions here go in without side access. Bedfordshire mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
How much does a terraced house rear extension cost in Bedfordshire?
A terraced house rear extension in Bedfordshire is priced at £2,170–£3,500 per square metre including VAT as a guide, before kitchen fit-out and fees. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4.5 m deep (13.5 m²) | £29,500–£47,000 |
| 3 m wide × 6 m deep (18 m²) | £39,000–£63,000 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Bedfordshire?
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.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

3 metres under permitted development in England, or up to 6 metres with prior approval outside designated land.
