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 Dudley?
In Dudley, 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 Dudley reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Dudley?
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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Underfloor heating option, electrics and plastering
- Building control completion
- Removal of internal and external walls
- Design and planning application
- Structural engineer’s design for steels and supports
- Walls, roof and glazing
How long does it take?
Allow 12 to 18 weeks on site. Allow time beforehand for drawings and approvals, usually 3 to 4 months.
