Types of Loft Conversions
Dormer Loft Conversion
The most popular and practical choice, adding headroom and floor space. Perfect for bedrooms, bathrooms, or offices — finished with custom storage, roof windows, and seamless integration with your existing home.
Mansard Loft Conversion
Designed for period or terraced properties. This conversion offers maximum internal volume with a flat roof and vertical rear wall, ideal for creating spacious, light-filled rooms.
Hip-to-Gable Loft Conversion
Great for semi-detached and detached homes. We extend the sloping side roof outward to form a full-height gable, creating a large, balanced living area.
Velux (Rooflight) Loft Conversion
The simplest and most cost-effective option, using skylights to transform your existing attic without altering the roof structure — ideal for home offices or hobby rooms.
