Side return extension in Weston-super-Mare
Infilling the narrow passage beside a Victorian or Edwardian back addition. We design, get the approvals for and build side return extensions in Weston-super-Mare and the surrounding area, with one contract from the first survey to building control sign-off.
Weston-super-Mare and its postcode districts BS22 and BS23 are part of our Somerset coverage. In Weston-super-Mare we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Do you need planning permission for a side return extension in Weston-super-Mare?
Whether your side return extension in Weston-super-Mare needs a planning application depends on its size, your house and any local restrictions.
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 Weston-super-Mare like to extend?
Stone-built and rendered houses are common around Weston-super-Mare, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
How a side return extension in Weston-super-Mare comes together
Survey visit
We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations
We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.
Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ
Side return extension questions in Weston-super-Mare
Can you match the brick or stone on my Weston-super-Mare house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How much does a side return extension cost in Weston-super-Mare?
As a guide, £2,390–£3,950 per square metre including VAT for a standard specification. For example, 2 m wide × 6 m deep (12 m²): about £28,500–£47,500 at that rate. Your written price follows the survey.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
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.
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.
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.
