Covering East Grinstead
We work in East Grinstead (RH19) and the places around it, including Horley, Crawley and Crowborough.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What is included in a wraparound extension in East Grinstead?
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.
- Party wall process with both neighbours if needed
- Pitched, flat or glazed roof with rooflights
- Optional kitchen supply and installation

Do you need permission for a wraparound extension in East Grinstead?
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 East Grinstead homeowners check first?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- An open-plan space this size needs a heating plan, often underfloor heating.
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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
