Terraced house rear extension in Blyth: rear and side return extensions for terraces, with access through the house and two neighbours. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Blyth (NE23 and NE24) as part of our Northumberland work. On a Blyth 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 Blyth?
Whether your terraced house rear extension in Blyth needs a planning application depends on its size, your house and any local restrictions.
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. 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 Blyth like to extend?
Terraces and semis are typical around Blyth. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Terraced house rear extension questions in Blyth
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.
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.
How do you keep the house clean?
Dust screens, floor protection and a single protected route through the house.
Can you match the brick or stone on my Blyth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How long does a rear extension take to build in Blyth?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
