Covering Llanelli
We work in Llanelli (SA15) and the places around it, including Pontarddulais, Swansea and Ammanford.
Homes in Dyfed
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 goes into a wraparound extension?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Planning and building regulations checks under Welsh rules
- Pitched, flat or glazed roof with rooflights
- Optional kitchen supply and installation
How much should I budget for a wraparound extension?

| Standard specification | £3,400 to £3,800 per m² |

| High specification | £4,250 to £4,700 per m² |
Planning and building rules in Llanelli
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
Wales has its own permitted development rules, set by the Welsh Government.
What can affect a wraparound extension?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- 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.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Wraparound extensions: common questions
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.
Glazed roof or solid roof?
A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.
