Double Storey Extensions in Greater London

Professional double storey extension across Greater London — free survey, fixed written quotes and guaranteed work.

If you need double storey extension in Greater London, our team delivers workmanship you can rely on, with no day-rate surprises.

We manage the whole project — design, trades and building control where needed — so you deal with one team. A two-storey extension is the most cost-effective way to add serious space — extra living space downstairs and a bedroom, bathroom or master suite above. Because the roof and foundations are shared across two floors, you get more room per pound than a single-storey build.

Our double storey extensions service in Greater London includes

  • Extra ground-floor living space and a room above
  • Matched brickwork and roofline to the existing house
  • Full structural design and building-control sign-off
  • New bedrooms, bathrooms or a master suite
  • Plumbing, heating and electrics extended cleanly
  • Fixed itemised quote after a free survey

We manage the added structural demands, matching brick and roofline, and tie the new floors neatly into the existing house. From design and building control to the final decoration, it is delivered by one team against a fixed, written price.
