What Are Maisonette Loft Conversions?

Maisonettes are common in London, and their name comes from the French term for a small house. You may also see some people referring to them as duplexes. They have their own entrances and one or two floors.

While ground-floor maisonettes with gardens can sometimes add an extension, upper-floor maisonettes have limited options for creating extra space.

However, in some cases, you can install a loft conversion, which can open up more living space and add value to your property.

Leasehold Maisonettes

It’s also important to remember that leasehold properties have different rules, as the freeholder must give permission for any changes to the property.

If you have a share of a freehold, you should find out who owns the freehold for the loft space and see whether it’s possible to obtain freeholder approval for your conversion.

In some cases, you can purchase the freehold of the attic or roof space. However, the process can be complex and long, so it’s essential to ensure everything is in place and legal before beginning the project.

Our experts can assess your property and advise on the next steps.

Are There Other Legal Requirements for a Maisonette Loft Conversion?

While many loft conversions fall under permitted development rights, this isn’t the case for maisonettes. If you want to make changes to the loft, you’ll need to obtain planning permission from your local planning authority.

The Benefits of a Maisonette Loft Conversion

There are multiple benefits associated with maisonette loft conversions, including:

  • More Living Space: Growing families can add extra bedrooms to their home without needing to move. In many cases, this saves money and creates a beautiful living space.

  • Higher Property Value: Maisonettes with extra floor space are more attractive to prospective buyers, adding 10%-20% to the property’s value.

  • Energy Efficiency: The type of conversion we create depends on your existing roof and whether there’s enough space. However, many conversions can increase natural light, thereby lowering your energy bills over time.

FAQs

How much does a maisonette loft conversion cost?

Maisonette loft conversions vary in cost depending on your roof space and the type of conversion we can offer. For example, a Velux loft conversion is often the more affordable option, but a mansard loft conversions generally cost more.

The amount of structural alterations can also add to your costs, as older buildings with traditional rafters require fewer structural changes than roofs with trusses.

The costs can range from £45,000 to over £120,000, but that doesn’t include purchasing the freehold.

Conversions of leasehold properties require the freeholder’s permission. If the freeholder isn’t willing to give permission, then you can potentially buy the rights to the loft space.

It depends on your roof’s height and pitch; steeper roofs often provide more space. A conversion will create extra room for an additional bedroom or living space, but we can give you a realistic idea of how much space your extension will make during the free site survey.
