Mansard loft conversions can often give the biggest results in terms of additional living space, although they generally also involve the most construction work. However, as with all London loft conversions, they are more affordable and less stressful than moving house.
What is a mansard loft conversion?
A mansard loft conversion is usually built to the rear of your property and alters the structure of your sloped roof so that it has an almost straight gradient of 72 degrees. Windows are built into the new roof structure as small dormers – you can even have a Juliet balcony – and the conversion is generally big enough to support multiple room configurations such as two bedrooms and a bathroom.
Mansard loft conversions are suitable for most types of properties – including mid-terraces – and can be finished in a variety of ways to match your property.
Because mansard loft conversions alter the structure of your home, they usually do require planning permission. You should always check with your Local Authority to find out about their planning policy requirements as some are stricter than others.
As well as planning permission, your completed mansard loft will require building regulations approval. Our FAQ section has more information on the processes involved in this and planning.
How much do London mansard loft conversions cost?
