Types of Loft Conversions We Offer
We provide a wide range of loft conversion solutions depending on your property type, roof structure, and budget.
Rear Dormer Loft Conversions
Rear dormer loft conversions are one of the most popular options in London. They extend vertically from the existing roof slope, creating additional headroom and floor space. This solution is ideal for terraced and semi-detached homes.
Mansard Loft Conversions
Mansard loft conversions involve altering the roof structure to create a nearly vertical rear wall and flat roof. They maximise usable space and are commonly seen in period properties across London.
Velux Loft Conversions
Velux (rooflight) loft conversions are a cost-effective solution that maintains the existing roofline. By installing roof windows, we create bright, airy spaces without major structural alterations.
Gable Loft Conversion
A gable loft conversion (often called hip-to-gable) extends the sloping side of the roof to create a vertical wall. This significantly increases internal loft space and is ideal for end-of-terrace or semi-detached houses.
