We manage the whole project — design, trades and building control where needed — so you deal with one team. A well-built extension adds space and lasting value to your home. We handle the whole job — design and drawings, building control and party-wall sign-off, foundations, structure and a full finish — so you deal with one accountable team from first sketch to final decoration.

Our house extensions service in Swansea includes

  • Free measured survey and design advice
  • Architectural drawings and building-control sign-off
  • Foundations, brickwork, steelwork and roofing
  • Plastering, electrics, plumbing and decoration
  • Party-wall and structural calculations arranged
  • Fixed written quote — no day-rate surprises

Every extension starts with a free site survey and a fixed, itemised quote. We manage structural calculations, steelwork and building regulations throughout, and keep the site clean and the schedule honest. The result is a room that feels part of the original house, not bolted on.
