A dormer extension can turn a cramped loft into a genuinely usable room, and it’s a popular option in Bury where many properties have steeply pitched roofs that limit headroom. Core Rock Ltd designs and constructs dormers that add real, usable space rather than just a token conversion.

We assess your roof structure and the room layout you want before recommending the type of dormer that will give you the best headroom and natural light for the space.

Construction is carried out with minimal disruption to the rest of the property, and we keep the site tidy and safe throughout, particularly important on terraced streets with limited access.

Our dormer work includes structural alterations, roofing and weatherproofing, insulation, and internal finishing. As with our loft conversions, building regulations approval is handled as part of the project so the finished space is fully compliant.
