Covering Horley
Alongside Horley, we also cover Crawley, Redhill (5 miles to the north) and Reigate.
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 is included in a house-to-flat conversion in Horley?
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
- Fire separation and sound insulation between flats
- Separate electrics, heating and metering
What will a house-to-flat conversion cost?
Indicative costs for house-to-flat conversions. London and the South East usually sit towards the top of each range.
Priced on survey.
What approvals does a house-to-flat conversion need in England?
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 can affect a house-to-flat conversion?
- Some councils restrict the loss of family houses or limit flat conversions in certain streets.
- Each flat needs its own utilities and metering.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- 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
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.
Can you visit a house in Horley to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
