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.
- Planning application and layouts to space standards
- Separate electrics, heating and metering
- Kitchens, bathrooms and finishes

How is a house-to-flat conversion approved in Sutton?

Dividing a house into flats always needs planning permission in England.
What can affect a house-to-flat conversion?

Your questions answered
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.
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.
How do I get a price for house-to-flat conversions in Sutton?
Use the guide price tool for a ballpark figure, then book a visit for a fixed written price for the agreed specification.
