With over 21 years of combined experience we deliver every project as a complete design, planning and build service. From your first consultation through to a finished conversion, everything is backed by our 10-year structural guarantee.
A dormer extends vertically out from the existing roof slope, creating a box-shaped structure with full-height walls and a flat or pitched roof. The result is significantly more headroom and usable floor space, making it one of the most popular loft conversions across Bristol's terraced and semi-detached housing.
Dormer ConversionsA hip-to-gable conversion replaces the inward-sloping hip end of a roof with a vertical gable wall, dramatically opening up the loft space beneath. It's the ideal solution for semi-detached and end-of-terrace homes in Bristol where the original roof shape limits headroom and floor area.
Hip-to-Gable Conversions
Ideal for homes with a rear outrigger. The L-shaped conversion uses two linked dormers (one on the main roof and one over the outrigger) to create substantial extra space with good headroom. A very popular choice for Bristol's properties.
L-Shaped ConversionsA Velux conversion installs roof windows directly into the existing roof structure without altering the roofline or requiring planning permission in most cases. It's the most cost-effective entry point into loft conversion, best suited to Bristol homes that already have good natural headroom and where budget or planning restrictions are a consideration.
Velux ConversionsModern homes built with trussed roofs aren't always considered convertible — but we can change that. A cut roof conversion involves carefully cutting and restructuring the existing roof trusses, installing steel supports to carry the load, and opening up the loft space for a full conversion.
Cut Roof ConversionsA wrap around loft conversion combines a hip-end dormer and a rear dormer into a continuous structure that wraps around the roof. It's the most space-maximising option for Bristol's hipped roof properties — semi-detached and detached homes where standard dormers alone would leave usable space unreached.
