Do you need planning permission for a terraced house rear extension in Lymm?
Here is how the rules in England apply to a terraced house rear extension in Lymm.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
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 Lymm like to extend?
Stone and brick terraces are common around Lymm. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier. In Lymm we plan the delivery route through the house and the skip licence before anything else.

Terraced house rear extension questions in Lymm
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
What postcode areas do you cover around Lymm?
Including WA13, and the surrounding Cheshire area.
Do both neighbours need party wall notices?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can I live at home while the extension is built?
