What goes into a dormer loft conversion?
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.
- Planning and building regulations checks under Welsh rules
- Steelwork and new floor structure
- Dormer frame, roof covering and cladding
