Mansard loft conversions are a popular way of creating additional living space in homes. They are known for providing a lot of headroom and usable floor space, making them a great option for homeowners looking to add an extra room or two. However, before embarking on a loft conversion project, it’s important to consider the cost. According to several sources, the mansard loft conversion cost can vary depending on the size and complexity of the project.
On average, a typical UK loft conversion will cost around £50,000. However, the final price can start at around £45,000 and exceed £90,000, depending on various factors that can impact the cost such as the quality and complexity of the build, materials and fittings used and location.
Understanding Mansard Loft Conversion
Mansard loft conversion is a popular type of loft conversion that involves raising the walls on one or both sides of the roof, creating a flat roof with a steeper pitch. This type of conversion is often used in urban areas where space is limited, and homeowners want to maximise the living space in their homes.
Mansard loft conversions are known for their unique look and style. They are often considered the most aesthetically pleasing type of loft conversion, and they can significantly increase the value of a property. However, they are also one of the most expensive types of loft conversion.
How much does mansard loft conversion cost?
Mansard loft conversion cost can vary depending on several factors, including the size of the roof, the materials used, and the location of the property and can range from £50,000 to £90,000.
One of the reasons why mansard loft conversions are more expensive than other types of loft conversions is that they require more structural work. The roof needs to be completely restructured, and the walls need to be raised to create the steep pitch. This requires a lot of planning, design work, and construction, which can add to the overall cost.
Despite the higher cost, mansard loft conversions are a popular choice for homeowners who want to add more living space to their homes. They offer a unique look and style, and they can significantly increase the value of a property. If you are considering a mansard loft conversion, it is essential to work with a reputable and experienced contractor who can help you create the perfect space for your needs.
Factors Influencing the Cost
The cost of a mansard loft conversion can vary greatly depending on several factors. Here are some of the most important factors that can influence the cost:
Size of the Loft
The size of the loft is one of the most significant factors that can influence the cost of a mansard loft conversion. The larger the loft, the more materials and labor will be required, which can increase the cost of the project.
Existing Roof Structure
The existing roof structure can also affect the cost of a mansard loft conversion. If the existing roof is in good condition and can support the additional weight of the conversion, the cost may be lower. However, if the roof requires significant repairs or reinforcement, the cost can increase.
Type of Loft Conversion
There are different types of loft conversions, and each type can have a different cost. For example, a mansard loft conversion is generally more expensive than a simple dormer conversion because it involves changing the entire sloping face of the roof to a near-vertical angle.
Style and Quality of Finishings
The style and quality of finishings can also affect the cost of a mansard loft conversion. Higher-end finishes, such as hardwood floors and custom-built cabinetry, can add to the cost of the project.
Location
The location of the property can also influence the cost of a mansard loft conversion. In general, the cost of living is higher in urban areas, and the cost of labor and materials may be higher as well.
Complexity of Design
The complexity of the design can also affect the cost of a mansard loft conversion. A more complex design may require more time and labor to complete, which can increase the cost of the project.
Overall, the cost of a mansard loft conversion can vary greatly depending on several factors. It is important to consider all of these factors when planning a loft conversion project to ensure that the project is completed within budget.
Mansard loft conversion calculator
Calculating the cost of a mansard loft conversion involves considering two main factors: the size of the conversion and the finish of the conversion and any extras. As mansard loft conversion involves changing the entire sloping face of the roof to a near-vertical angle (at least 72 degrees), it means structural change to the entire roof, so the bigger the home, the greater the cost.
With the finish, if you choose to have a bathroom installed, for example, you have to pay for the cost of the suite and other elements in the finish, which can add several thousands of pounds to the overall cost of the project. Other mansard loft conversion costs can be broken out from this basic calculation.

Average Cost of Mansard Loft Conversion
Mansard loft conversions are a popular way to add extra space to a property. However, the cost of such a conversion can vary depending on several factors. In this section, we will explore the average cost of a mansard loft conversion based on size, location, and design.
Based on Size
The size of the loft being converted is one of the most significant factors affecting the cost of a mansard loft conversion. The larger the loft, the more materials and labor will be required, and the higher the cost will be. On average, the cost of a mansard loft conversion is around £50,000. However, this can vary depending on the size of the loft being converted.
Based on Location
Location is another factor that can affect the cost of a mansard loft conversion. In general, the cost of a loft conversion will be higher in London and other major cities than in other parts of the UK. This is because labor and materials tend to be more expensive in these areas. On average, the cost of a mansard loft conversion in London can range from £60,000 to £120,000, while in other parts of the UK, it can be around £40,000 to £60,000.
Based on Design
The design of the loft conversion can also have an impact on the cost. For example, if the loft requires extensive structural work, this will increase the cost. Similarly, if the loft conversion requires additional features such as skylights, dormer windows, or a balcony, this will also increase the cost. On average, the cost of a basic mansard loft conversion with no additional features is around £50,000. However, this can increase to £80,000 or more if additional features are required.
In summary, the cost of a mansard loft conversion can vary depending on several factors, including the size of the loft, the location of the property, and the design of the conversion. It is essential to work with a reputable and experienced loft conversion company to ensure that the project is completed to a high standard and within budget.
Additional Costs to Consider
When planning a mansard loft conversion, there are additional costs to consider beyond the initial construction expenses. These costs can vary depending on the size and complexity of the project, as well as the location of the property.
Planning Permission
Before starting any construction work, it is important to determine whether planning permission is required. Mansard loft conversions typically require planning permission, which can cost around £200 payable to the local council. It is important to note that planning permission can take several weeks or even months to obtain, so it is important to factor this into the overall timeline and budget.
Interior Design
Once the construction work is complete, there are additional costs to consider for the interior design of the new space. This can include furniture, fixtures, and decor. The cost of interior design can vary widely depending on the style and quality of the items selected.
It is important to consider the overall budget for the project when selecting interior design elements. Some homeowners may opt for budget-friendly options, while others may choose to invest in high-end finishes and furnishings.
Ultimately, the additional costs to consider when planning a mansard loft conversion will depend on a variety of factors. By carefully considering all of these expenses, homeowners can ensure that they have a realistic budget for their project and can avoid any unexpected surprises along the way.

How to Keep Your Mansard Loft Conversion Costs Down
When it comes to keeping costs down for a mansard loft conversion, hiring experienced and reliable tradespeople is key. One option is to hire an architect to plan and oversee the entire project, hiring a team of builders and other necessary trades. Another option is to hire a specialist loft conversion firm that already has a team with all the needed skills.
Project managing the work yourself is also an option, but it requires a lot of attention to ensure each stage runs to schedule and does not cause delays. This may involve hiring different tradespeople for different elements of the build, such as a carpenter, electrician, and plumber.
Another way to keep costs down is to consider a smaller conversion. Loft conversion costs are typically calculated by multiplying the usable gross internal area by the finished build cost per square metre. By reducing the size of the conversion, you can save money on both materials and labour costs.
Using off-the-shelf materials and finishes can also help to keep costs down. Custom or bespoke finishes can be expensive, so opting for standard materials and finishes can help to reduce costs without compromising on quality.
Finally, it is important to have a clear and realistic budget in mind before starting the project. This can help to avoid overspending and ensure that the project stays on track financially.
