Types of Loft Conversion

Our experts help you to select and plan the right type of loft conversion for your home and family. Choosing the right type isn’t just important for the room’s feel and function; you could avoid entering the planning process by making the smart choice, or your options may be restricted by your home or area.

Velux Loft Conversion

Velux loft conversions tend to be the most common, fastest to build, and cheapest to complete. Changes to the roof are very limited, so there is no time spent constructing dormers or changing the shape of the exterior – we simply add Velux windows to the roof, reinforce the existing structure, create access, and make the space habitable. While these benefits are a large draw for a lot of clients, Velux conversions also tend to have the smallest interiors as the conversion is entirely built in the existing roof space without any expansion.

Because Velux conversions make so few changes to the exterior of your home, they can usually be built as permitted developments without needing to go through the process of gaining planning permission.

Hip to Gable Loft Conversion

Hip to Gable loft conversions allow you to expand on the existing structure by increasing the amount of headspace available in part of the conversion. This is often a good choice for detached houses – where you can change both ends to gables – or loft spaces where there isn’t much room for a staircase.

Unlike a Velux loft conversion, hip to gable conversions make a large change to the home’s exterior so often require planning permission.

Dormer Loft Conversion

Building a dormer loft conversion involves adding dormer boxes to the exterior of the roof to provide windows and additional headspace to the loft. These conversions take a little longer to build than Velux loft conversions, but do offer larger interior spaces and a beautiful traditional look to the exterior.

Dormers are built away from your home and are added to the structure once they are ready. While this work requires more time (and is generally more costly) than Velux conversions, it is occasionally possible to build them as permitted developments.

Mansard Loft Conversion

Mansard loft conversions offer the largest interior spaces of all the loft conversion types. It involves completely removing part of the roof and adding two more sides, so that a cross-section of the roof becomes a rectangle rather than a triangle. This means that you have more typical, box-shaped rooms rather than a sloping ceiling in the interior.

If you would like to make the most of the space, it is possible to create double-mansard loft conversions where we build out both sides of the roof. However, Mansard conversions almost always require planning permission due to the large changes to the exterior of the building.
