House-to-flat conversions in Hounslow

Covering Hounslow

Hounslow is about 10 miles west of London. We also cover Isleworth (1 miles to the north-east), Heston and Richmond.

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.

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 should Hounslow homeowners check first?

Some councils restrict the loss of family houses or limit flat conversions in certain streets.
Each flat needs its own utilities and metering.
