Wraparound extension in Widnes
Thinking about a wraparound extension in Widnes? An L-shaped extension that fills the side return and runs across the back. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.
We cover Widnes (WA7 and WA8) as part of our Cheshire work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Cheshire where a side return alone would leave the room too narrow.

How much does a wraparound extension cost in Widnes?
For Widnes we work from the North West England rate: £2,070–£3,380 per square metre of new floor, including VAT, standard specification. North West prices sit below our West Midlands baseline; access on terraced streets is the main variable.

| L-shaped, about 30 m² of new floor | £62,000–£101,500 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a wraparound extension in Widnes?
Planning for a wraparound extension in Widnes follows the English householder rules.
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 Widnes like to extend?
Stone and brick terraces are common around Widnes. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Wraparound extension questions in Widnes
How long does a rear extension take to build in Widnes?
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.
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
