Wraparound extension in Sinfin
For homes in Sinfin, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
We cover Sinfin (DE1, DE23 and DE24) as part of our Derbyshire work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Derbyshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Sinfin?
Here is how the rules in England apply to a wraparound extension in Sinfin.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
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. 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 Sinfin like to extend?
Sinfin has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

FAQ
Wraparound extension questions in Sinfin
Do I need planning permission for a rear extension in Sinfin?
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.
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.
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.
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.
Is the site visit in Sinfin free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
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.
