Rear extensions that open up your ground floor

A rear extension is a proven way to modernise the heart of the home—expanding kitchen and dining space, adding a snug, or creating a new family room that opens to the garden.

We design the extension to complement the existing architecture and we pay close attention to roof forms, drainage routes and finishes so it looks and feels cohesive.

We’ll also help you navigate approvals, from planning permission to Building Regulations, and keep neighbours informed where needed. If you are exploring your options, you can request a fixed-price quotation or browse recent work in our projects gallery.

Common features in rear extensions

Small design choices make a big difference to comfort and usability.

  • Large glazed doors for garden access and natural light.
  • Rooflights or lanterns to brighten the centre of the plan.
  • Open-plan layouts with defined zones for cooking and dining.
  • Utility spaces and smart storage to reduce clutter.
  • Finishes that link old and new (floor levels, thresholds and trim details).

Our build method

We plan the work to keep your home secure and functional during the build. Temporary weatherproofing, clear site management and weekly progress updates are part of how we reduce disruption.

If you’re considering a wider transformation, a rear extension can pair well with a side return or wrap-around for maximum effect.

We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.

Why a rear extension is popular

  • Strong return on investment when executed well.
  • Creates modern open-plan living without changing the whole house.
  • Works across many property types in Surrey and SW London.
  • Improves daylight and the indoor-outdoor connection.
