There are many different types of loft conversions to choose from and we are here to help you make the most informed decisions on the design phases and building implementation to make the best use of your loft space.

Dormer Conversion

Dormer Structures increase the overall room space to a Loft Conversion, where the most common structures are either Pitched Roof or Flat Roof.

Mansard Conversion

A Mansard Loft conversion is a 2-slope structure that increases room size, requires extra structural work and is often found in older properties.

Hip-to-Gable Conversion

A Hip to Gable loft conversion is often found most popular with detached or semi-detached homes where the shape of the roof of the home is changed.

Velux Conversion

A Velux Loft Conversion is cost effective solution that minimises construction work to use existing headroom and maximise overall room space.
