Do you need planning permission for a terraced house rear extension in Bedford?
Here is how the rules in England apply to a terraced house rear extension in Bedford.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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. 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 Bedford like to extend?
Bedford mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

FAQ
Terraced house rear extension questions in Bedford
How much does a terraced house rear extension cost in Bedford?
As a guide, £2,170–£3,500 per square metre including VAT for a standard specification. For example, 3 m wide × 4.5 m deep (13.5 m²): about £29,500–£47,000 at that rate. Your written price follows the survey.
Can you match the brick or stone on my Bedford house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can a terrace have a two-storey rear extension?
It is possible but harder to get through planning because of the effect on both neighbours.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
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 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.
