What is a Mansard Loft Conversion?

A mansard loft transformation completely changes the structure of a slanting rooftop and, at 72 degrees, makes it nearly vertical. This type of conversion allows for usable space to be maximised within the loft, giving more headroom and generally a less box-like dashboard compared to dormer conversions. Depending on your space needs and local building codes, mansards can be built at the front, back, or both ends of a property.

Benefits of a Mansard Loft Conversion

Increased Space

The most prominent benefit to getting a mansard loft conversion is increased available space. Near vertical walls and a flat roof provide an airy space for a potential extra bedroom, master suite, or home office.

Aesthetic Appeal

Mansards are a favourite for their architectural charm. Unlike other types of loft conversions, they have a clean finish and flow that usually fits in well with the style of most properties. Naturally, they are popular in conservation areas, as they help preserve the area's aesthetics.

Enhanced Property Value

One of the reasons that you want to knock through for a mansard roof is because your property value will go up. For example, here in London, a mansard conversion can add up to around 20% on top of the value and, therefore, is a great return, so you are not only creating more space but also increasing your assets.

Planning and Design Considerations

Planning Permission

Due to the structural changes associated with this type of work, a mansard loft conversion typically requires planning permission. The process takes up to 8 weeks, so it needs to be considered in the project schedule. That said, mansard conversions tend to be successful in conservation areas, given their relatively unassuming design.

Design and Build Process

Here at Deluxe Lofts, we deliver it all from design and build service. We have a team of professionals that will take care of everything from the survey and architectural plans to obtaining permission by planning to build it for you. The process looks like this

  1. Initial Consultation and Survey: We will provide an on-site visit to gather your requirements, understand what you ideally need from the new space, and assess whether a mansard conversion is feasible.

  2. Design and Planning: Architectural drawings specific to your design are prepared by our Architects. Planning included (we will apply for planning permission).

  3. Construction: After approval, our builders will begin development with the least amount of alternating in your daily lifestyle that you can attain.

  4. Completion: Once the construction is over, we will go through a full inspection, and you will receive all the necessary certificates.

Case Study: Transforming a Victorian Terrace in London

We recently completed a mansard loft conversion on this Victorian terrace in North London. The homeowners wanted a bedroom and the en suite of everyone's dreams. We created a rear Mansard with massive glazing to bring in all the natural light. The outcome was an amazing open-plan loft, which greatly contributed to the potential value of the property. This project took only 10 weeks to complete, and our clients were ecstatic with the change.
