Wraparound extension in Abbots Langley
We plan and build wraparound extensions for homeowners in Abbots Langley. 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.
We cover Abbots Langley (WD5) as part of our Hertfordshire work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Hertfordshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Abbots Langley?
The planning route for a wraparound extension in Abbots Langley 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. 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 Abbots Langley like to extend?
Post-war semis and newer estates are typical of Abbots Langley, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.
