Covering Seaham
Our coverage around Seaham (SR7) also includes Houghton-le-Spring, Sunderland and Washington.
Homes in the North East
Housing across the North East ranges from colliery terraces and Tyneside flats to suburban semis and modern estates, each with different options for extending.
What is included in a wraparound extension in Seaham?
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.
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights
What will a wraparound extension cost?
Indicative costs for wraparound extensions. London and the South East usually sit towards the top of each range.
| Wraparound extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,400 to £3,800 per m² |
| Good specification | £3,800 to £4,250 per m² |
| High specification | £4,250 to £4,700 per m² |
Do you need permission for a wraparound extension in Seaham?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
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. Most need householder planning permission, which usually takes around eight weeks once validated.
What should I think about before starting?
- Both neighbours may need party wall notices.
- Roof water from an L-shape needs careful falls and outlets.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
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.
