The most popular conversion in London. A dormer extends out from your sloping roof to add full head height and real floor space, ideal for a terrace or a semi.
Your roof now What we build
A dormer builds out from the slope of your existing roof to create a box-shaped extension with flat walls and a flat or pitched roof. That change is what gives you full standing height across most of the new room, rather than the cramped headroom a bare loft leaves you with.
It is the conversion most London terraces and semis end up choosing, because it adds the most usable space for the money and suits the majority of roof shapes. On a typical home a rear dormer gives you room for a double bedroom and an en-suite, with proper windows for light.
Five stages, one named project manager, and a written price before anyone lifts a tool.

No two roofs are the same, so treat the range as a starting point rather than a price. The survey is free and the written price that follows it is fixed.
What it depends onAn indicative market guide only, not a quote. The cost depends on your roof, the type of conversion, the spec and the finish. After a free survey we give you one fixed written price, with no hidden extras.
A rear dormer is often allowed under permitted development, but flats, conservation areas and some designs need full permission. We check this for you on the free survey and handle any application.
A dormer gives you full standing height across most of the new room, which is why it is the go-to choice where a plain loft is too low to use.
Most builds are a matter of weeks rather than months. We give you a firm timeline at survey and keep to it, with one project manager on your job start to finish.
A well-built loft conversion can add up to twenty percent to the value of your property, as well as the extra bedroom or office you need now.
Yes. Most dormers comfortably take a double bedroom and an en-suite, and we design the layout around how you want to use the space.
A semi-detached home where the loft was storing suitcases. A full rear dormer turned it into a double bedroom with its own shower room, and the front of the house is unchanged from the street.
