The height from the new floor to the ridge, taken over where the stair will land. We measure it on the first visit, before a drawing exists and before you have paid for one.
The ceiling is highest at the ridge and lowest where you walk in. Only one of those places matters.
Fifty on a semi. It is cumulative across the life of the house, so a previous extension has already spent some of it.
Served before work starts, not when it suits the programme. We start that clock at the survey.
The drawing
Scroll, and the section builds. This is the drawing we would put in front of you at the second meeting, and it is the one that decides whether you have a bedroom or a very expensive cupboard.
What we do
Dormer, hip-to-gable and rooflight conversions, drawn to the ridge height you actually have.
02Single and double storey, through the planning route the site actually allows.
03Measured survey, planning drawings, structural calculations, building control.
04One team on one job at a time, one written programme, and one person who answers the phone when you ring about it.
How it goes
An hour at the house. We measure the ridge, the stair, and the ceiling joists, and we tell you on the day whether the room you are imagining exists.
Everything recorded properly and drawn up as existing. This is the drawing every later decision is checked against.
Two or three options drawn, and the planning route named: permitted development, prior approval or full application. The route changes the programme more than the design does.
Steel sizes calculated by our engineer, drawings submitted, the building control route agreed before anyone lifts a tile.
Eight to twelve weeks for a typical dormer conversion. One team, on your job, until it is finished.
What people say
They told us at the first visit that the ridge was too low for the bedroom we wanted and drew us a study instead. Every other firm had quoted the bedroom.
The programme said ten weeks and it took ten weeks. After two previous builders I had stopped believing that was possible.
The structural engineer walked the roof himself before the steels were specified. It sounds obvious and apparently it is not.
Where we work
An hour at the house tells you whether the room you are picturing is possible. If it is not, you will know that day and it will not have cost you anything.
