Transform Your Loft Into a Beautiful, Functional Living Space
Unlock hidden space in your home with bespoke loft conversions — ideal for bedrooms, offices, or studios.
Make the Most of Your Roof Space
A loft conversion is a smart way to add valuable space and increase property value without extending your home’s footprint. Whether you want a master suite, guest bedroom, office, or creative space, we offer end-to-end loft conversion services — from planning and structural design to build and finish.
Types of Loft Conversions We Build
Dormer Loft Conversions
A popular choice that extends your roof vertically to add full-height headroom. Ideal for adding spacious bedrooms or bathrooms.
Hip-to-Gable Conversions
Perfect for semi-detached or end-of-terrace homes — this conversion straightens the roof’s slope to create more usable floor space.
Mansard Loft Conversions
Maximise your roof’s potential with a full-width mansard conversion, ideal for large master suites or multiple rooms.
Velux (Rooflight) Conversions
The most cost-effective option — using existing roof space and installing rooflights to add light and ventilation without altering the roofline.
L-Shaped Loft Conversions
Often used on Victorian and Edwardian properties, this design links two dormers to form an L shape, offering generous living or sleeping space.
