Wraparound extension in Derby
For homes in Derby, 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 Derby (DE1, DE3, DE21 and DE22) 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.

How much does a wraparound extension cost in Derby?
A wraparound extension in Derby is priced at £2,130–£3,490 per square metre including VAT as a guide, before kitchen fit-out and fees. East Midlands prices sit a little below our West Midlands baseline.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £47,000–£77,000 |
| L-shaped, about 30 m² of new floor | £64,000–£105,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a wraparound extension in Derby?
The planning route for a wraparound extension in Derby is set by England's householder rules and your council.
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. 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 Derby like to extend?
Derby has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both. In Derby we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

FAQ
Wraparound extension questions in Derby
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.
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 long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Do you handle building control in Derby?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Is the site visit in Derby free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Derby?
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.
