How is a house-to-flat conversion approved in Warminster?

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 can affect a house-to-flat conversion?

  • Each flat needs its own utilities and metering.
  • Mortgage lenders and freehold arrangements need early legal advice.

  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
