Do you need planning permission for a side return extension in Southport?
Whether your side return extension in Southport 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. 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 Southport like to extend?
Stone and brick terraces are common around Southport. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

Side return extension questions in Southport
Is the site visit in Southport free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Southport 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 my neighbour's permission?
Not their permission, but in England and Wales you must serve party wall notices, and a neighbour can consent in writing or ask for a surveyor's award.
How long does a rear extension take to build in Southport?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
What postcode areas do you cover around Southport?
Including L22, L30, L37, L38, PR8 and PR9, and the surrounding Merseyside area.
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.
