VELUX Conversion 

A VELUX Conversion is the fastest and most cost-effective loft conversion solution. It does not require altering your roofline, making it ideal for lofts with adequate headroom. Since it does not involve changing rooflines, conversion can be done without seeking planning permission in most cases. Using rooflight windows from global brand VELUX, we turn lofts into bright, healthy and energy-efficient living spaces.

Dormer Conversion

A dormer conversion involves reconstructing a section of a pitched roof to allow more headroom and floor space into a loft. Unlike a Mansard and hip-to-gable loft conversion, construction is simpler in this work. Compared to a VELUX conversion, the dormer loft conversion allows you to add more architectural features, such as a proper staircase or a balcony with French doors.

Hip-to-Gable Conversion

The hip-to-gable conversion is the best option for a subtle roof and floor extension. It is ideal for bungalows, detached and semi-detached homes, as well as houses with terraces. This type of conversion makes the roof alteration appear seamless, giving you added space without the new construction look. The hip-to-gable conversion is also flexible, allowing you to combine VELUX windows and dormers.

Mansard Conversion

With a roof that is almost horizontal and sides with a 72-degree pitch, the Mansard conversion gives the biggest headroom and floor space.  It generally costs more than the other loft conversion types, but it gives homeowners more options in designing and using the space. The Mansard conversion is ideal for detached and semi-detached properties as well as homes with a terrace.  It is usually done at the property’s rear.
