What we do
Rung 01
The roof keeps its shape and the light comes in through the slope. The cheapest, quickest way to a room, if you have the height.
From £32,000. About 5 to 6 weeks.
Rung 02
A box built out from the ridge at the back. Most of the floor becomes full height. The usual way to fit a bedroom and an ensuite.
From £42,000. About 7 to 8 weeks.
Rung 03
The sloping end of your roof becomes a straight wall. On a 1930s semi it adds the room you need for a staircase and a real bedroom.
From £55,000. About 8 to 10 weeks.
Rung 04
A shower room under the eaves, with built-in cupboards where the ceiling is low. Ensuite adds from £5,500.
Ensuite adds from £5,500.
Rung 05
The staircase decides the whole loft. We plan it first: headroom, the landing you lose and the fire route out.
Included in every conversion. Oak upgrade from £1,800.
Rung 06
Drawings and calculations that building control will accept. Included in every job, or £1,650 for your own builder.
Included. Drawings-only package £1,650.

Usually four to five months for building, and two to three weeks for a survey. Lawful Development Certificates add around eight weeks, so start early.
Boarding and a ladder, yes, from £1,400, as long as you understand it is a storage space, not a room, and it cannot be called a bedroom.
Measure joist to ridge and try the checker. Then book a free survey: Dai or Bethan will tell you what is possible, what it costs, and whether you should leave it alone.
