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 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
  • Fire separation and sound insulation between flats
  • 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 Calne

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

Dividing a house into flats always needs planning permission in England.

What should I think about before starting?

  • Some councils restrict the loss of family houses or limit flat conversions in certain streets.
  • Each flat needs its own utilities and metering.

From first call to completion

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

Your questions answered

Does converting a house into flats need planning permission?

Yes, always. Subdividing a house into flats is development under planning law.

How much does a flat conversion cost?

It varies too much to give a reliable guide figure, so we price each one on survey. The reduced 5% VAT rate can apply where the number of dwellings changes.

Can you visit a house in Calne 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.
