Extensions

We can help with design and build house extensions across London—adding space, light, and better flow, from kitchen-diners to extra rooms and full open-plan ground floors. We manage the project end-to-end, coordinating trades and keeping the build organised from foundations through to finishing.​

Extension types we deliver

• Rear extensions: the most common way to expand a kitchen/living area into the garden.​

• Side return extensions: ideal for Victorian/Edwardian terraces to use the narrow side alley space.​

• Wrap-around extensions: a rear extension combined with a side return to create an “L-shape” footprint and maximise space.

• Single- and double-storey extensions: depending on the extra space you need and what planning allows.​

Planning and Building Regulations

Some single-storey rear extensions may be possible under permitted development (subject to size limits and conditions), while larger or more complex extensions often require planning permission. Building Regulations approval still applies, covering key areas like structure, insulation/energy performance, drainage, and safety.

What’s included

We typically handle: groundworks and foundations, structure and steelwork for open-plan layouts, roofing and windows/doors, first fix plumbing/electrics, plastering, flooring, kitchen/bathroom fit-out (if included), and final decoration. The exact scope depends on whether you want a shell build or a complete “ready to live in” finish.
