House-to-flat conversions: common questions

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.

Who deals with the council for a project in Wiltshire?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
