How Can You Convert Your Loft Space?
Dormer Loft Conversion
One of the most common choices, a dormer loft conversion extends vertically from your existing roof to create additional headroom and floor space. Perfect for bedrooms, offices or bathrooms, dormers are cost-effective and suit most property styles.
Velux (Rooflight) Loft Conversion
A Velux conversion makes use of your existing loft space by adding roof windows for light and ventilation. It’s the most affordable option, requires minimal structural changes, and is ideal if your loft already has good head height.
Hip-to-Gable Loft Conversion
For semi-detached or detached homes with a hipped roof, a hip-to-gable conversion extends the roofline vertically to maximise interior space. This option is popular with families who need an extra bedroom or larger living area.
Mansard Loft Conversion
Mansard conversions alter the roof structure at the rear of the property to create a steep slope and almost vertical wall. This option provides the most additional space and design flexibility, making it perfect for creating master suites or multiple rooms.

"Lewys and Liam are very efficient carpenters. They cleared my old rotting decking, mended and painted my fence and installed a fairly large amount of composite decking. It looks absolutely beautiful and I'm sure has added value to my home. They are lovely people and very trustworthy to leave alone in your home. Thank you for the excellent job. Caradie James"
