Covering East Grinstead
We work in East Grinstead (RH19) and the places around it, including Horley, Crawley and Crowborough.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What is a house-to-flat conversion?
We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.
- Planning application and layouts to space standards
- Fire separation and sound insulation between flats
- Bin, cycle and amenity space works
How much should I budget for a house-to-flat conversion?
What house-to-flat conversions typically cost. These are guide ranges; the written quote for your house replaces them.
Priced on survey.
Do you need permission for a house-to-flat conversion 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.
Dividing a house into flats always needs planning permission in England.
What can affect a house-to-flat conversion?
- Each flat needs its own utilities and metering.
- Sound insulation between flats is tested on completion.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.
