Mansard Loft Conversions Cost Guide

Mansard loft conversions are an innovative way of gaining more space in the house you love. At Extension Architecture we specialise in creating unique solutions for your property, allowing you to utilise the valuable floor space that you have tied up in the loft and create additional living space. They are built to the rear of properties and change a slanted roof into an almost straight one, giving you plenty of room to play around with the layout. Some Mansard loft conversions can be big enough for two bedrooms and a bathroom too. Mansard loft conversions are named after Francois Mansard, a prominent 17th-century French architect and have long been a popular way to maximise space by converting the attic.

Why Choose A Mansard Loft Conversion?

Mansard loft conversions are suitable for a wide range of houses, including semi-detached and terraced properties. In London, Mansard loft conversions remain a popular choice for homes that need more space, and they can be an affordable way to upgrade your property. A Mansard loft conversion can take anywhere between eight and ten weeks, so it’s a relatively quick process too. If you’re expecting a new addition to the family or you need a home office, a Mansard Loft conversion provides the most space possible for your property. This style of loft conversion is ideal for an open plan, modern layout. It can also add significant value to your home for the future.

What Does A Mansard Loft Conversion Cost?

There are a lot of factors that affect how much a loft conversion costs. You can choose several options but a Mansard loft conversion tends to be more expensive as it requires considerably more construction work. You’ll find that a loft conversion is far easier and more affordable than moving house, especially with London loft conversions. In general, a Mansard loft conversion costs between £45,000 to £70,000.

You can choose additional features for your Mansard loft conversion like a Juliet balcony, dormer windows and high-end materials and finishes. The bigger the extension and the more premium finishes chosen will increase the price too. Costs will include scaffolding, alterations to the roof structure, joinery, plastering and labour, so it is important you create and stick to a detailed budget. Think about what kind of stairs you will need as well as whether you need any plumbing. You will also need to set aside funds for plans, surveys and any bathrooms or wetrooms that you want to install.
