Homes in West Glamorgan
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What does a wraparound extension involve?
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
- Party wall process with both neighbours if needed
- Optional kitchen supply and installation

Do you need permission for a wraparound extension in Swansea?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Wales has its own permitted development rules, set by the Welsh Government. Small single-storey rear extensions can often go ahead without an application, but the limits differ from England's and there is no larger-extension prior approval route, so we check the current Welsh rules for your house before drawings are finalised.
What should Swansea homeowners check first?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Both neighbours may need party wall notices.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Around 12 to 18 weeks on site after approvals.
Glazed roof or solid roof?

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.
