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 Ashington?
In Ashington, a wraparound extension typically costs £2,000–£2,900 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £56,000–£81,000. We start from a UK-wide guide and adjust it for the North East, where labour and materials are typically about 10% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (20 m²) | £40,000–£58,000 |
| Typical project (28 m²) | £56,000–£81,000 |
| Larger project (39 m²) | £78,000–£113,000 |

Your quote will depend mainly on:
- Total footprint and the amount of glazing
- Drainage changes
- Kitchen and flooring specification
- Access for materials on terraced streets
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a wraparound extension in Ashington?
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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about wraparound extensions in Ashington
Do you build wraparound extensions in Ashington?
Yes. We build wraparound extensions across Ashington, including postcodes NE63. Every project starts with a free home visit.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
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.
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.
