Double Storey Extensions in Swansea

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

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

Our work is guaranteed, our quotes are fixed in writing, and our tradespeople are vetted and insured. 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.

  • 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
