Wraparound extension in Knaresborough
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Knaresborough and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Knaresborough (HG5) as part of our North Yorkshire work. Wraparound projects around Knaresborough often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Knaresborough?
Here is how the rules in England apply to a wraparound extension in Knaresborough.
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. 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 Knaresborough like to extend?
Stone terraces and brick semis are typical of Knaresborough. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.
