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?

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
  • Fire separation and sound insulation between flats
  • Separate electrics, heating and metering

What will a house-to-flat conversion cost?

Guide prices for house-to-flat conversions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.

Priced on survey.

Planning and building rules in Barnes

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.

What are the steps?

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

What people ask before starting

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.

Yes. Barnes is within our coverage for house-to-flat conversions, along with nearby Chiswick and Putney.
