Most Popular Loft Conversion Types

Dormer Loft Conversion

A dormer loft conversion is one of the most popular types of loft conversion. It involves vertical expansion of an existing roof to create more headroom and floor space. A dormer loft conversion usually includes adding a flat-roof extension which creates more space and allows windows to be installed.

A dormer loft conversion is ideal for creating additional bedrooms or living spaces, providing plenty of natural light and ventilation.

On average, you can expect to pay from £2,000 for a small conversion up to £60,000 for a conversion covering over 20 square meters.

Hip-to-Gable Loft Conversion

A hip-to-gable loft conversion involves extending an existing roof by replacing the sloped side with a vertical wall, creating more space and height. This type of loft conversion is ideal for properties with hip roofs where the roof slopes in all directions.

A hip-to-gable loft conversion can provide a significant amount of additional living space and is perfect for creating extra bedrooms or more spacious living areas.

The average cost of a hip-to-gable loft conversion is around £35,000–£65,000 for a typical semi-detached house, while a detached house conversion typically costs £40,000–£75,000. This, of course, depends on the size of the property.

Mansard Loft Conversion

A mansard loft conversion is a more complex type of loft conversion that involves changing the shape of the roof to create more living space. This conversion usually entails expanding the roof on both sides, creating a flat roof with a sloped front.

Mansard loft conversions are popular in areas where it's harder to get planning permission, as they often require minimal changes to the roof line. They're ideal for creating additional living space or a home office.

The cost of a mansard loft conversion ranges from £30,000 for a 30 square meter build up to £75,000 for a 50 square meter conversion.

Velux Loft Conversion

A Velux loft conversion is the simplest type of loft conversion and involves adding skylights to existing loft space. This type of conversion is ideal for properties with high ceilings and sufficient headroom.

They are perfect for creating additional bedrooms or home offices, providing plenty of natural light and ventilation.

A Velux loft conversion is relatively inexpensive and can provide significant additional living space. You can expect to pay on average around £15,000–£20,000.
