Do you need planning permission for a side return extension in Louth?
The planning route for a side return extension in Louth is set by England's householder rules and your council.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
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 Louth like to extend?
Louth has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

What postcode areas do you cover around Louth?
Including LN11, and the surrounding Lincolnshire area.
Is the site visit in Louth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Glass roof or solid roof with rooflights?

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

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
