Wraparound extension in Carlisle

We plan and build wraparound extensions for homeowners in Carlisle. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.

Carlisle is covered from our Cumbria round, including CA1, CA2 and CA3. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Cumbria where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Carlisle?

Here is how the rules in England apply to a wraparound extension in Carlisle.

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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Carlisle like to extend?

Stone and brick terraces are common around Carlisle. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  4. Fixed price and build

    A written price for the agreed design, a start date and a named contact through the build, ending with the building control completion certificate.

FAQ

Wraparound extension questions in Carlisle

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.

How long does a rear extension take to build in Carlisle?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Will it take a lot of garden?

Less than a deep rear extension of the same area, because part of the space comes from the side passage.

Do I need planning permission for a rear extension in Carlisle?

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.

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.

Is the site visit in Carlisle free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.
