House-to-flat conversions in London

Covering London

Our house-to-flat conversions service in London covers Brent, Islington, Bexley and Barking and more.

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 does a house-to-flat conversion involve?

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.

What will a house-to-flat conversion cost?

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 London?

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.

What can change the price or programme?

Some councils restrict the loss of family houses or limit flat conversions in certain streets.
Sound insulation between flats is tested on completion.

From first call to completion

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

What people ask before starting

Yes, always. Subdividing a house into flats is development under planning law.

Yes. We check the council’s policies first and only proceed with a design that has a realistic chance of approval.
