Covering Dorchester
We work in Dorchester (DT1) and the places around it, including Weymouth, Bridport and Yeovil.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
What is 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.
- Design, planning drawings and structural calculations
- Steel frame or goalpost for the corner opening
- Optional kitchen supply and installation
How much should I budget for a wraparound extension?
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 |
How is a wraparound extension approved in Dorchester?
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 Dorchester 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.
From first call to completion
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Wraparound extensions: common questions
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
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.
Who deals with the council for a project in Dorchester?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
