What Is a Mansard Loft Conversion?

A mansard conversion modifies the structure of your roof to create a near-vertical rear wall, typically sloping at a 70-degree angle. This type of conversion is particularly effective for maximising the space in Victorian and Georgian terraced houses, where traditional pitched roofs often limit usable loft space. Mansard lofts often cover the full width of your property, creating ample room for additional bedrooms, bathrooms, or office space.

A key feature of mansard lofts is their flexibility; they can accommodate large windows or even balconies, allowing for plenty of natural light and ventilation. Whether you opt for a standard mansard or an L-shaped mansard loft conversion, you can expect a modern, spacious addition to your home.

Why Choose a Mansard Loft Conversion?

  1. Maximise Space
    Unlike other types of loft conversions, a loft conversion mansard roof makes the most of the available headroom and floor space. Its near-vertical walls offer much more usable room compared to a typical dormer or Velux loft conversion. This makes it ideal for properties where space is at a premium, particularly in terraced and semi-detached homes.By opting for a double mansard loft conversion, you can extend this design across both the front and rear of your property, allowing for even greater expansion. This is particularly beneficial for homes in densely populated areas where expanding outward is not possible.
  2. Aesthetic Appeal
    One of the standout advantages of a mansard conversion is how seamlessly it integrates with the existing architecture of your home. The flat or shallow sloping roof at the top ensures that your house retains its visual appeal while gaining much-needed space. For period homes, particularly Victorian and Georgian styles, mansard conversions blend beautifully with the overall design, maintaining the character of the property.If you’re considering an L-shaped mansard loft conversion, this design option not only adds a large, flexible space but also offers additional design possibilities, such as an en suite bathroom or a small balcony. It’s a great way to enhance both the practicality and style of your home.
  3. Increase Property Value
    Loft conversions are one of the most cost-effective ways to add value to your home. A well-executed mansard conversion can boost your property’s value by up to 20%. In areas with high demand for additional living space, such as urban or suburban environments, the appeal of a loft conversion is undeniable. Homebuyers are increasingly looking for properties that offer flexibility and additional rooms, making a mansard conversion a highly attractive investment.
  4. Planning Permission Considerations
    While most loft conversions fall under permitted development, a loft conversion mansard roof typically requires planning permission due to the significant changes made to the roof’s structure. This process can be smooth if handled correctly, and reputable loft conversion companies will guide you through the planning stages.The advantage of a mansard conversion is that, once approved, it often covers the full width of the property, maximising the living space and avoiding the need for future extensions. Many homeowners find that the benefits of the extra space far outweigh the potential complexity of obtaining planning permission.

Different Types of Mansard Conversions

Standard Mansard Loft Conversion
This is the most common type of mansard conversion, where the rear slope of the roof is almost vertical. It provides ample space for additional rooms, such as a master bedroom with an en suite, a home office, or a guest bedroom. The flat top of the mansard can be fitted with skylights, allowing natural light to flood into the space.

Double Mansard Loft Conversion
For homeowners seeking maximum space, a double mansard loft conversion offers the ultimate expansion. By adding mansards to both the front and rear of the property, this conversion creates a significant amount of living area without altering the footprint of the house. This is particularly beneficial for terraced homes where extending outward is not an option.

L-Shaped Mansard Loft Conversion
An L-shaped mansard loft conversion is ideal for properties that already have an extension or an L-shaped layout. By building the conversion in an L shape, you create a seamless flow between the existing structure and the new loft space. This type of conversion is perfect for homeowners looking to add multiple rooms, such as a bedroom with an en suite and a home office, while retaining a cohesive design.
