Why a loft conversion is one of the most cost-effective ways to add space and value to your home.
A single-storey house extension in London typically costs between £45,000 and £90,000 depending on size, finish, and structural complexity. Zonex Group provides a fixed price quote after a free consultation and site survey, so there are no hidden costs once work begins.
Most house extensions take between 10 and 16 weeks from groundworks to completion, depending on scope. Zonex Group provides a full project timeline at the quotation stage as part of our project management process.
Many single-storey extensions fall under Permitted Development Rights and don't need full planning permission, but this depends on your property, its size, and local council rules. Zonex Group handles planning permission applications and building regulations approval as part of our design and build service.
