What is a Mansard Loft Conversion?

A Mansard loft conversion is one of the best ways to maximize your living areas, especially in London, where property prices are high and space is limited. It offers significant increases in room size, making it a popular choice for homeowners looking to add value and functionality to their homes.

Although it requires more construction work than other loft conversions, it remains a cost-effective and less stressful alternative to moving house.

The Key Advantages of a Mansard Loft Conversion

Discover why Mansard loft conversions are the preferred choice for London homeowners

Maximizes Space

Unlike other loft conversions, a Mansard conversion significantly increases usable floor space and head height, making it feel like a natural extension of your home.

Enhances Property Value

A Mansard loft conversion can add substantial value to your commercial and domestic property, making it a worthwhile investment.

Attractive Design

The design fits well with both traditional and modern homes, improving the overall look of the property.

More Natural Light

Mansard lofts often include dormer windows or French doors with Juliet balconies, which allow more natural light into the living areas.

Flexibility in Design

You can customize your Mansard loft to include bedrooms, bathrooms, home offices, or even an entertainment zone.

Expert Installation

Our team of professionals ensures a high-quality, safe, and compliant Mansard loft conversion for your property.

Planning Permission and Regulations

Since a Mansard loft conversion involves altering the roof structure, planning permission is usually required. Here are some key points to consider:

Planning Permission

Most London boroughs require approval before starting a Mansard loft conversion due to the major structural changes involved.

Building Regulations

Following building regulations is necessary to ensure safety and structural integrity.

Party Wall Agreement

If your home is a semi-detached or terraced property, you may need an agreement with your neighbors before work begins.

Conservation Areas

If your home is in a conservation area, additional restrictions may apply.

Dormer vs. Mansard Loft Conversions: Key Differences

Understanding which loft conversion is right for your property

Feature Dormer Loft Conversion Mansard Loft Conversion
Roof Structure Maintains original sloped roof with an added dormer box Replace one entire roof side with a near-vertical wall
Space Added Moderate increase Maximum increase
Planning Permission Often not required Usually required
Cost Lower than Mansard Higher due to structural changes
Aesthetic Box-like appearance Seamless, blends with home design

A Mansard conversion is ideal if you need a large, open area, while a Dormer conversion may be better for a smaller upgrade with minimal structural changes.

Types of Mansard Loft Conversions

Mansard loft conversions are a popular choice for homeowners looking to maximize living areas and add value to their property. They involve raising the party walls and creating a nearly vertical back wall with a flat or gently sloping roof.

Rear Mansard Loft Conversion

1. Rear Mansard Loft Conversion

The most common type where the rear slope of the roof is altered to create a near-vertical wall, increasing headroom and usable space.

Best For:

Victorian and Georgian terraced homes, where space at the back allows for expansion.

Benefits:
  • Maximizes interior areas
  • Improves property worth
  • Works well with traditional architecture
Front Mansard Loft Conversion

2. Front Mansard Loft Conversion

Similar to the rear Mansard, but applied to the front of the property. This is less common and may require special planning permissions.

Best For:

Properties in conservation areas or those looking for a symmetrical front and rear extension.

Benefits:
  • Offers additional room without changing the rear height
  • Keeps the look consistent
  • Provides better roadside traction
Double Mansard Loft Conversion

3. Double Mansard Loft Conversion

A combination of both front and rear Mansard conversions effectively added a full additional floor to the home.

Best For:

Properties in need of maximum room, such as townhouses and period properties.

Benefits:
  • Gives the most added room
  • Ideal for creating multiple rooms or self-contained units
  • Great for rental properties or large families
L-Shaped Mansard Loft Conversion

4. L-Shaped Mansard Loft Conversion

This involves extending the Mansard conversion over an existing rear extension, creating an L-shape.

Best For:

Homes with rear extensions, particularly Victorian and Edwardian properties.

Benefits:
  • Create multiple useful areas, such as an additional bedroom and bathroom
  • Optimizes the footprint of the house
  • Great for maximizing floor area without extending the ground floor
Side Mansard Loft Conversion

5. Side Mansard Loft Conversion

Constructed on the side of the property, this type of Mansard conversion is suitable for detached and some semi-detached homes with enough side roof space.

Best For:

Homes with sufficient roof width, especially detached houses.

Benefits:
  • Makes use of unused roof area
  • Provides additional living areas without altering the main façade
  • Less intrusive than a full Mansard extension
