Types of Home Extensions in London

Single-Storey Extension London

A single-storey extension in London is perfect for homeowners looking to add space to their ground floor. Common uses include kitchen expansions, open-plan living areas, and home offices.

Double-Storey Extension London

For those needing significant extra space, a double-storey extension in London provides additional rooms on both floors, increasing living and sleeping areas without taking up too much garden space.

Side Return Extension

A side return extension utilizes the narrow space at the side of your house, making it ideal for terraced and semi-detached homes. This extension type is commonly used to expand kitchens and dining areas.

Rear Extension

A rear extension extends the back of the house, creating a larger living area or a bigger kitchen. It’s a great option for homes with gardens, offering a seamless indoor-outdoor flow.

Wrap-Around Extension

A wrap-around extension combines both a side return and a rear extension, maximizing ground-floor space. This is a great solution for homeowners who want an open-plan design with plenty of natural light.

Kitchen Extension London

A kitchen extension in London can completely transform your home, creating a modern, spacious cooking and dining area. Whether you opt for a rear or side return extension, this upgrade enhances both functionality and aesthetics.
