What does a dormer loft conversion involve?

A dormer loft conversion builds a box-shaped extension out from the rear slope of the roof, creating vertical walls and full head height across most of the new floor. It is the most popular type of loft conversion because it gives the most usable space for the cost.

  • Steelwork and new floor structure

What approvals does a dormer loft conversion need in Wales?

In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.

Wales has its own loft and roof permitted development rules. Rear dormers within set volume limits are often allowed, but the detail differs from England's, so we confirm the current Welsh limits against your roof before the design is fixed.

What should Ammanford homeowners check first?

  • Dormer cheeks close to a shared wall can trigger the Party Wall Act.
  • L-shaped dormers are common on Victorian terraces with a rear outrigger.
