Ground Floor Extension FAQ
How much does a ground floor extension cost in London? +
Ground floor extensions in London start from around £2,000 per square metre for a basic single-storey build, rising to £2,500 for a higher specification and £3,000 or more for a detailed design. The final figure depends on the size, the glazing and the finishes you choose.
Do I need planning permission for a ground floor extension? +
Many ground floor extensions fall under permitted development, so planning permission is not always needed. Larger extensions, homes in conservation areas and most flats will usually need a full planning application. We assess your project and advise which route applies before any work begins.
How long does a ground floor extension take to build? +
Most ground floor extensions take between 12 and 20 weeks on site, depending on the size and complexity of the build. The design and planning stage beforehand typically adds a few months, so it is worth starting early.
What types of ground floor extension are there? +
The main types are rear extensions, which add space across the back of the house, side return extensions, which fill the narrow alley to the side, and wraparound extensions, which combine both. We help you choose the layout that gives you the most usable space.
Can I stay in my home during a ground floor extension? +
Most people stay at home throughout the build. There will be some disruption, particularly if the work affects the kitchen, so planning ahead for temporary arrangements makes the process much easier.
