Terraced house rear extension in Birmingham
We plan and build rear extensions for terraced houses for homeowners in Birmingham. Rear and side return extensions for terraces, with access through the house and two neighbours. Start with a free site visit, then a written price once the design is agreed.
Birmingham is covered from our West Midlands round, including B6, B8, B19 and B23. On a Birmingham terrace both neighbours usually need party wall notices or agreement, so we talk to them early.

Do you need planning permission for a terraced house rear extension in Birmingham?
Here is how the rules in England apply to a terraced house rear extension in Birmingham.
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.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Birmingham like to extend?
Red-brick terraces and 1930s semis make up much of Birmingham. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

FAQ
Terraced house rear extension questions in Birmingham
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 I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
Can you match the brick or stone on my Birmingham house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
