A double Mansard loft conversion offers one of the most comprehensive and transformative options for homeowners looking to reimagine their living space. With a design that creates both a front and rear Mansard, this type of conversion is a great way to maximise space and functionality. However, from design to planning permissions and constructions, there are few factors that need to be considered before opting for this type of conversion, which we will delve into in depth in this guide.
What Is a Double Mansard Loft Conversion?
A “mansard” structure is generally constructed at the rear of the property and involves modifying the roof slope to consist of a nearly vertical back wall and a flat roof.
A “double Mansard” loft conversion takes this design a step further by applying the same structure to both sides of your property. This essentially replaces the existing pitched roof with a fully usable new floor. It is one of the largest and most extensive loft conversion types and is ideal for homeowners who need additional space for their growing families.
Why Choose a Double Mansard Loft Conversion?
There are many reasons why a double Mansard loft conversion might be the right choice for your home. Here are some of the key benefits –
1. Expanding Living Space
By replacing your pitched roof with a vertical structure on both the front and rear, you can create a brand-new floor. This extra space can accommodate multiple rooms, such as additional bedrooms, a study or even a self-contained suite. Whether your family is growing or you need a more spacious environment, a double Mansard is the perfect solution.
2. Flexible Layout Options
One of the biggest advantages of a double Mansard conversion is the versatility it offers. With its rectangular shape and flat roof, you gain maximum usable floor area. This gives you the freedom to design the space around your needs, from a luxurious master bedroom with an en-suite to a large open-plan family area for families with children.
3. Preserves Architectural Aesthetics of Period Properties
If you live in a period home, such as a Victorian property, a Mansard loft conversion is often the best option for preserving the character of the building. Mansard loft conversions blend seamlessly with traditional architecture, ensuring that your new space complements the look and feel of your home while enhancing its functionality.
4. Maximise Natural Light
Even though the Mansard design has steep vertical walls, clever placement of windows, skylights and balconies ensures plenty of natural light, creating a bright and inviting atmosphere.
5. Adds Long-Term Value
A double Mansard loft conversion is an investment with substantial returns. While maximising the space of your property, it also increases the property’s market value significantly due to its additional storeys and flexible layouts.
6. Future-Proofing Your Home
Whether you are planning for a growing family, working remotely and need additional workspace or simply want a home that adapts to your changing lifestyle, a double Mansard loft conversion ensures your property is future-ready as it gives you the flexibility to reconfigure spaces as your needs evolve.
Factors That Determine the Cost of a Double Mansard Loft Conversion
The cost of a double Mansard loft conversion project can vary depending on several factors, few of which include;
1. Size and Scale of the Project
The overall size of your property and the dimensions of the loft space are major factors in determining the cost. Larger homes require more materials and labour, which can impact the overall costs.
2. Structural Considerations
A double Mansard conversion involves altering the roof structure, which means your home will need to be assessed to ensure it can handle structural changes such as reinforcements to the foundation or walls.
3. Planning Permission
Planning permission is usually required for a double Mansard conversion, as it involves significant changes to the exterior of your home and roof structure. Therefore, the cost of obtaining planning approval should also be factored in.
4. Materials and Finishes
The type of materials, such as high-end appliances or bespoke features and finishes, you choose for the build will impact the cost. Costs of adding features such as en-suite bathrooms, adding balconies or additional storage solutions also need to be factored in.
