Mansard Loft Conversion in London
A Mansard loft conversion is a wise investment if you need more room and want to make the most of your roof space. This loft conversion is a practical way to add more space by using your roof, which is ideal for creating large, versatile rooms without the need to extend your home’s footprint.
We deliver high-quality conversions built around your layout, style and long-term needs, handling every stage with precision and care.
What Is a Mansard Loft Conversion?
A Mansard loft conversion is one of the most effective ways to add an extra floor of usable space to your property. This type of conversion alters the roof’s structure by raising the party wall and creating a near-vertical back wall with a flat roof, leaving you with a generously sized, full-height room that feels like a natural extension of your home.
Perfect for various properties, especially in built-up or terrace-style areas, a Mansard conversion in London is ideal for maximising your living space and creating a long-term solution for a growing household.

The Benefits of a Mansard Conversion
If you’re thinking about expanding your home, here’s why a Mansard loft conversion in London could be the right choice:
Maximise Usable Space
With full-height ceilings and minimal sloping, a Mansard conversion provides the most headroom and floor space of any loft type.
Ideal for Larger Rooms
Whether you want a master bedroom with en-suite, a home office or a full guest suite, the shape and size of a Mansard build offer flexibility in layout and function.
Blends Seamlessly with Your Property
The flat-roofed rear extension can easily complement your home’s architecture, making it ideal for period and modern properties.
Increase Property Value
Mansard conversions add significant square footage, which translates directly into higher market value for your home.
Long-Term Investment
Unlike more compact conversions, Mansard lofts offer lasting usability – perfect if you plan to live in your home long term.
Ideal for Terraced and Urban Homes
Mansard conversions work especially well on terraced and end-of-terrace homes where roof space is otherwise limited.
While a Mansard conversion gives you the most internal space, other styles like a Dormer conversion or a Velux loft might suit homes with existing headroom or limited planning constraints
