Types of Loft Conversions

Dormer Loft Conversion

Generally the most popular and quickest conversion you can have. This conversion gives you more headroom and floor space than other conversions and usually do not require any planning permission.

Mansard Loft Conversion

These conversions come with a flat roof and a back wall that slopes at 72 °. They create a lot more living space but do require planning permission.

Velux Loft Conversion

These conversions use your existing roof structure so are not suitable for all lofts. They are a cost effective way of adding more living space and planning permission is generally not needed.

Hip-to-Gable Loft Conversion

This conversion maximises available space, but are only suitable for detached and semi-detached properties. They will need planning permission to convert but the additional space makes this worth while.
