A dormer extension is one of the most effective ways to add headroom and natural light to a loft space. Core Rock Ltd provides dormer construction services across Horwich, tailored to suit the style and structure of your property.

From initial design through to construction, we handle the technical requirements of dormer work carefully, ensuring the extension is structurally sound and finished to a high standard both inside and out.

Whether you’re planning a full loft conversion or simply want to improve an existing space, a dormer can make a real difference to how your Horwich home functions.

We can build flat roof, gable-fronted, or hip-to-gable dormers depending on what best suits your property and planning requirements, and we handle liaison with building control throughout. Every dormer is fully weatherproofed and finished internally to match the rest of the loft space.
