What is a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.
How much does a wraparound extension cost in Brighouse?
In Brighouse, a wraparound extension typically costs £2,050–£3,000 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £57,500–£84,000. That range is adjusted for Yorkshire and the Humber, where domestic building work typically costs around 7% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Brighouse?
Here is how the rules work for a wraparound extension in England. In England a wraparound extension combines side and rear elements, which normally takes it outside permitted development, so a householder planning application is made.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about wraparound extensions in Brighouse
Who approves a wraparound extension in Brighouse?
Planning matters in Brighouse go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.

Will both neighbours be affected?
Usually only the neighbour on the side return side, but rear foundations near either boundary can trigger party wall notices.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
What about the old back addition?
The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
