Wraparound extension in Hampton Wick
For homes in Hampton Wick, 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.
Hampton Wick and its postcode districts KT1, KT2 and TW11 are part of our Greater London coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Greater London where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Hampton Wick?
The planning route for a wraparound extension in Hampton Wick is set by England's householder rules and your council.
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. 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 Hampton Wick like to extend?
Much of Hampton Wick is 1920s and 1930s semis and short terraces with longer gardens than inner London, which suit full-width single-storey rear extensions. Parking suspensions, skip licences and controlled hours on residential streets shape the programme more than the build itself.
