Loft Conversion Types

You can choose from a wide variety of loft conversion designs such as Dormers, Mansards, Hips to Gables, Veluxes, etc. Local authorities will permit loft conversions based on the existing layout of the roof and certain restrictions.
A free, no-obligation Powerpillar visit can advise you on this matter.

Dormer Loft

The Dormer loft is built on top of an existing sloped roof, thus squaring off the top. The building work involved is relatively straightforward. Powerpillar across London has completed several of these projects.

L Shape Mansard

The property would need a back addition to construct an L-shaped mansard roof. At the back of the house, there is often a kitchen and bathroom. Consequently, this area can accommodate the mansard. A Victorian property in London is most likely to have one of these.

Velux Loft

Velux refers to one of the most well-known window brands, not the type of roof structure. Powerpillar loft conversion specialist in London will ensure the best of this conversion.

Hip to Gable

In most cases, we perform hip-to-gable conversions on detached, semi-detached or end-of-terrace houses. Roofs with hipped ends slant in either direction or have both ends slanting. Perpendicular to the slope, the awning extends outward.

What is the cost of converting a dormer loft?

Dormer lofts typically cost between £30,000-£60,000 more than Velux lofts. A dormer requires a much more tremendous amount of work to convert the attic into a living space, as well as a complete redesign of the roof layout and design. The floor joists may also need to be replaced.

Due to the way hip-to-gable conversions are installed, they tend to cost more than dormer lofts. As a result, the price can rise from £40,000 to £65,000.

What is the cost of converting a mansard?

In total, mansard loft spaces cost approximately £45,000 to £70,000. It depends on how the loft is designed and how it works with the roof of the house.
