Covering Brent
Our coverage around Brent (HA9) also includes Wembley, Harrow and Greenford.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
What is 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
How much should I budget for a house-to-flat conversion?

Planning and building rules in Brent
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. 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.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
