Wraparound extension in Welling
We plan and build wraparound extensions for homeowners in Welling. 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.
Welling and its postcode districts DA6, DA15 and DA16 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.

How much does a wraparound extension cost in Welling?
A wraparound extension in Welling is priced at £2,860–£4,680 per square metre including VAT as a guide, before kitchen fit-out and fees. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.

| L-shaped, about 22 m² of new floor | £63,000–£103,000 |
| L-shaped, about 30 m² of new floor | £86,000–£140,500 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a wraparound extension in Welling?
Here is how the rules in England apply to a wraparound extension in Welling.
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 Welling like to extend?
Much of Welling 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.
