Dormer Loft Conversion

A full rear-dormer loft conversion on a 1930s semi — strip-out, steels, new floor, and a full-width timber dormer framed up and sheathed ready for cladding.

  • /Roof strip-out and chimney breast cut-back
  • /Structural steels and new floor joists
  • /Full-width rear dormer — timber frame
  • /Breathable sheathing and warm-roof build-up
  • /Scaffold and weather protection throughout

/ The job

How it came together.

The brief was to turn an unused loft into a proper master bedroom with an en-suite, using a full-width rear dormer to maximise head height and floor area.

We stripped the rear slope back to the rafters, cut the redundant chimney breast back to ceiling level on a gallows bracket, and dropped in the new structural steels to carry the loft floor.

From there we laid the new floor joists, framed up the full-width dormer in C24 timber, and sheathed the outside in breathable board ready for the EPDM roof and zinc-effect cladding.

Scaffold and a temporary tin-hat roof kept the house watertight throughout — the family stayed in residence with no exposure to the weather.
