Mansard Conversion in Richmond and West London
A Mansard conversion can significantly increase the usable space within your roof by reshaping much of the existing roof structure. 100 Lofts can help you develop a well-planned loft that provides generous headroom, a more practical layout and a comfortable connection with the rest of your home.
From the initial design and planning stages through to structural work, roofing, insulation, stairs, joinery and finishing, we coordinate the project with care.

A loft with greater flexibility
Mansard conversions are designed to maximise the usable area within the roof, making them a practical option for creating a substantial additional room. The altered roof profile can provide more consistent ceiling height and greater freedom when arranging the space.
This can make the finished loft suitable for a spacious bedroom, home office, guest accommodation or another room that needs more than a small amount of additional floor area. We consider how you want to use the space before developing the layout, so the design reflects your priorities rather than simply adding square footage.
Planning the details from the outset
A successful Mansard conversion involves more than changing the shape of the roof. The position of the staircase, structural requirements, insulation, natural light, storage and internal layout all need to work together.
Our team at 100 Lofts can provide design and layout advice, technical drawings, planning guidance where required and assistance with party wall agreements. We then coordinate the construction stages, including structural alterations, roofing, weatherproofing, insulation and internal works.
The aim is to make the process straightforward to understand while ensuring the important practical details are considered before work begins.

Bringing the new space together
Once the structural work is complete, the interior needs to feel like a natural part of your home. We can incorporate bespoke joinery, useful storage and finishing details that make the additional space comfortable and practical for everyday use.
Access is another important part of the design. A well-positioned staircase can connect the new room with the rest of the property without making the existing floors feel compromised. We consider these relationships as part of the wider layout, helping the completed loft feel properly integrated.
Where appropriate, a Mansard design can also be combined with other loft features to maximise the available space and natural light.
One managed approach from design to completion
With a Mansard conversion, several stages need to be carefully coordinated. We provide support throughout the project, helping bring together the design, structural works, roofing, insulation, joinery and final finishes.
We can also assist with wider home improvement projects, including extensions, renovations, kitchens, bathrooms, structural alterations and roofing. If your loft conversion is part of a larger renovation, this approach lets you consider the different elements together.
