Covering Crowborough
Alongside Crowborough, we also cover Tunbridge Wells, East Grinstead (9 miles to the north-west) and Tonbridge.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What goes into a house-to-flat conversion?
A house-to-flat conversion divides a single house into two or more self-contained flats, each with its own front door, kitchen and bathroom. It always needs planning permission and full building regulations approval, particularly for fire separation and sound insulation between flats.
- Planning application and layouts to space standards
- Separate electrics, heating and metering
- Kitchens, bathrooms and finishes
What will a house-to-flat conversion cost?
Use these ranges to budget for house-to-flat conversions; the survey turns them into a fixed price for the agreed specification.
Priced on survey.
Planning and building rules in Crowborough
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. Councils assess flat sizes (many use the nationally described space standard), parking, bins, cycle storage and the effect on family housing supply.
What should Crowborough homeowners check first?
- Some councils restrict the loss of family houses or limit flat conversions in certain streets.
- Sound insulation between flats is tested on completion.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Your questions answered
Does converting a house into flats need planning permission?
Yes, always. Subdividing a house into flats is development under planning law.
Can you help with the planning case?
Yes. We check the council’s policies first and only proceed with a design that has a realistic chance of approval.
Who deals with the council for a project in Crowborough?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
