Covering Finchley
Our coverage around Finchley (N3) also includes Muswell Hill, Cricklewood and Kilburn.
Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
What is included in a house-to-flat conversion in Finchley?
We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.
- Feasibility check against local planning policy
- Planning application and layouts to space standards
- Fire separation and sound insulation between flats
How much should I budget for a house-to-flat conversion?
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.
Do you need permission for a house-to-flat conversion in Finchley?
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?
- Each flat needs its own utilities and metering.
- Sound insulation between flats is tested on completion.
How does the project run?
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
Does converting a house into flats need planning permission?
Yes, always. Subdividing a house into flats is development under planning law.
Can you help with the planning case?
Yes. We check the council’s policies first and only proceed with a design that has a realistic chance of approval.
Can you visit a house in Finchley 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.
