Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What is included in a house-to-flat conversion in Barnet?

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.

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 change the price or programme?

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