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 Worcestershire?
In Worcestershire, a wraparound extension typically costs £2,150–£3,100 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £60,000–£87,000. Prices in the West Midlands sit near the national average for this kind of work, and the range for Worcestershire reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Worcestershire?
Whether you need planning permission depends on your house and its location 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Questions about wraparound extensions in Worcestershire
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.
Who approves a wraparound extension in Worcestershire?
Planning matters in Worcestershire go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
How long does it take to build?
Around 12 to 18 weeks on site after approvals. Design, planning and party wall matters usually take 3 to 4 months beforehand.
Is a wraparound worth it?
It gives the biggest ground-floor space without going upwards. Whether it adds value depends on your street and house, so we suggest checking local sale prices before committing.
