Homes in Yorkshire and the Humber
Across Yorkshire and the Humber, older stone and brick terraces sit alongside inter-war semis and newer estates, and dormers and rear extensions are designed to suit each.
What do you get with a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Design, planning drawings and structural calculations
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights

Do you need permission for a wraparound extension in Northallerton?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.
What should Northallerton homeowners check first?
- Both neighbours may need party wall notices.
- Roof water from an L-shape needs careful falls and outlets.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Can we keep part of the kitchen working?
Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
