Dormer loft conversions
Dormers that begin with your roof
Every project starts with understanding your roof structure, ridge height, and ambitions — not with a standard dormer template.
We visit your property, assess the existing roof and floor structure, and discuss how a dormer could transform the space above. From there, we develop designs for dormer type, window placement, and internal layout that guide structural work, building regulations, and finishing.
Whether you need a flat-roof dormer to create a generous master bedroom, a gabled dormer that suits a period property, or an L-shaped dormer across the rear elevation, we refine every detail until the extension feels like it was always part of your home. Our dormers are designed and built by experienced loft specialists — so the space you approve is the room you receive.
What we deliver
Every detail considered
Flat-roof dormers
