Wraparound extension in Childwall

For homes in Childwall, 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.

Childwall and its postcode districts L15, L16 and L18 are part of our Merseyside coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Merseyside where a side return alone would leave the room too narrow.

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

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

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 Childwall like to extend?

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

How a wraparound extension in Childwall comes together

  1. Survey visit

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

  2. Design and guide price

    Two or three layout options with a guide price for each, so you choose the design knowing what it costs.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.

FAQ

Wraparound extension questions in Childwall

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

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

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

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 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.

Can you match the brick or stone on my Childwall house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

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.
