Wraparound extension in Kettering
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Kettering and the surrounding area, with one contract from the first survey to building control sign-off.
Kettering is covered from our Northamptonshire round, including NN15 and NN16. Wraparound projects around Kettering often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Kettering?
Here is how the rules in England apply to a wraparound extension in Kettering.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Kettering like to extend?
Kettering has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

FAQ
Wraparound extension questions in Kettering
Is the site visit in Kettering free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Kettering?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is it worth it over a side return alone?
If you want a dining table and a sofa as well as the kitchen, usually yes.
Do I need planning permission for a rear extension in Kettering?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Can you match the brick or stone on my Kettering house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
