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 Pembroke Dock?
In Pembroke Dock, a wraparound extension typically costs £2,000–£2,950 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £56,000–£82,500.

- Drainage changes
- Kitchen and flooring specification

Do you need planning permission for a wraparound extension in Pembroke Dock?
Whether you need planning permission depends on your house and its location in Wales. In Wales a wraparound extension combines side and rear elements; it can only be permitted development if each part meets the limits, so many need a householder planning application.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

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.
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.
