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 Flint?
In Flint, 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. We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (20 m²) | £40,000–£59,000 |
| Typical project (28 m²) | £56,000–£82,500 |
| Larger project (39 m²) | £78,000–£115,000 |
| Rate per m² | £2,000–£2,950 |
Your quote will depend mainly on:
- Party wall surveyor fees for one or both neighbours
- Kitchen and flooring specification
- Access for materials on terraced streets
- Steelwork and propping of the existing house

Do you need planning permission for a wraparound extension in Flint?
Approvals for a wraparound extension in Flint follow the rules for 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
