The largest of all loft conversions, a double mansard loft conversion is the installation of a complete additional storey onto the home. Adding an incredible amount of space to an existing property, a mansard loft conversion is the premier way to increase space and value to your home and is a sought-after extension in London and other areas around the UK. In today’s post, we’re going to be looking at this conversion type in more detail, as well as how it differs from another couple of popular conversion types – the dormer and the hip-to-gable.
Key Takeaways
- A mansard loft conversion is the largest type of loft conversion.
- Mansard roofs provide superior headroom compared to other types of loft conversion.
- Constructed to fit in with the existing house style, mansard conversions are aesthetically-pleasing.
What Does a Mansard Roof Look Like?

One of the problems with other types of loft conversion is the sloping roof. Despite the addition of dormer windows in many cases, headroom is still limited and can prevent the loft extension from truly feeling like full rooms. A mansard roof loft conversion solves this problem by replacing the standard roof with a new flat roof and near-vertical wall, providing the maximum amount of space for rooms in the extension. A mansard roof slants at 72° and typically includes dormer-style windows to provide fully vertical window space.
With a design aesthetic that’s in keeping with the original house construction, a mansard roof fits in perfectly with existing architecture, with the effect being that it looks more like a taller house, rather than one that has had a loft conversion.
There are three types of mansard roof loft conversions; a single mansard conversion where only the rear of the property is altered, an L-shaped mansard which provides a greater internal area that allows for an additional room, and the full double mansard loft conversion which utilises the full footprint of the home for the greatest possible size of extension.
Mansard Loft Conversions vs. Dormer and Hip-to-Gable Loft Conversions

A double mansard roof loft conversion is the largest possible loft conversion and offers a significant increase in space and headroom when compared to the other loft conversions. Like a hip-to-gable conversion, it often does include dormer sections for the installation of fully vertical windows to make use of that additional ceiling room. However, as the entire roof is lifted, a mansard conversion represents a far larger end result and a more standard room shape when compared to that provided by a dormer loft conversion.
Single mansard and L-shaped mansard conversions typically include dormer elements to the opposite sides, mixing the two styles seamlessly for a pleasing overall look. Unlike hip-to-gable, dormer and Velux loft conversions, however, a mansard roof removes the slanting ceiling that can limit the use of the room’s sides.
The Benefits of a Mansard Loft Conversion
There is no loft conversion option that provides more space than a mansard roof. With a mansard conversion, the loft space is truly converted into an additional floor of the property, providing multiple rooms for any use. Consider the rooms on any other storey of your property where multiple bedrooms, bathrooms and other spaces exist. With a double mansard loft conversion, that can be replicated almost in its entirety.
Bedrooms that enjoy a superior view and brighter natural light; a large room dedicated for use as a work-from-home office; a fully-equipped family bathroom; a playroom; expansive storage – they’re all possible. With access to the entire floorspace, it is far easier to design a full staircase that is a continuation of the main stairs, and even include an upper landing area. With a full-sized conversion, so much is possible. Plus, there’s no having to duck your head to get to the corners.
Truly, the mansard loft conversion is an enviable addition to any home that will prove to be a strong investment in years to come. Remember, though, that a mansard loft conversion is a more significant undertaking than other loft conversions. Consequently, it is both more expensive and requires a longer construction time. Planning permission is essential in almost all projects, along with detailed architectural plans and a party wall agreement where there are adjoining properties.
