Loft Conversion Types
Dormer Loft Conversions
A Dormer loft conversion involves extending the existing roof vertically to create additional headroom and usable space. Typically built with a flat or pitched roof, dormers project out from the slope of your existing roofline, providing a more spacious and light-filled loft area. This style blends well with many property types and is one of the most popular and versatile loft conversion options.
Mansard Loft Conversion
A Mansard loft conversion involves raising the party walls and constructing a new roof with a steep 72-degree slope at the rear of the property. This creates a large, box-shaped loft space with full-height ceilings and generous room proportions. Common in Victorian and Georgian terraces, Mansard conversions provide maximum living space and a stylish, contemporary appearance.
Hip to Gable Loft Conversions
Designed for properties with hipped roofs, such as semi-detached or detached homes, a Hip to Gable conversion involves extending the sloping side of the roof to form a vertical gable wall. This modification increases internal space dramatically and creates a more practical loft area. Often combined with a rear dormer for even greater effect, this conversion complements the property's overall look.
Velux Loft Conversions
A Velux (rooflight) loft conversion retains your existing roofline, with no structural changes to the roof itself. Instead, Velux roof windows are installed to bring in natural light, creating a bright and airy new space. Ideal for lofts that already have sufficient head height, this is the least disruptive and most cost-effective conversion option, maintaining the external character of your home.
