Loft Conversion: Mansard
Expanding into your roof with a mansard loft not only gives you an extra room (or two, or three), it increases your property’s value and — crucially — does so in a visually striking way. Seen those Instagram influencers’ beautiful attics? You can achieve that chic look too.
Mansard loft conversion: key fact
This is one way of increasing usable space in your house amongst many others, so it’s worth thinking about the finer details, to be sure you choose the best option. Get to know more about this type with our guide. You can expect:
- Attractive end result
- Sizeable space added
- Suitable for all properties: terraced/semi-detached/detached
- Mid-price point compared to other styles
- Considerable amount of construction work
- Typically requires planning permission/building regulations approval
- Usually built at rear
- Flat roof and sloping, almost straight wall (72 degrees)
- Small dormer windows
- Juliet balconies possible
What could you use it for? There are lots of possibilities, including:
- Bedrooms: most popular choice, consider if you’d prefer one large one with a walk-in wardrobe, en-suite bathroom etc, or two smaller ones
- Office: work from home in style with a dedicated room away from living areas, helping to differentiate between family time and work mode
- Nursery: baby’s own haven with plenty of opportunity to grow into
- Bathroom: especially important when adding sleeping sanctuaries at the top of the house, choose from a WC only, shower cubicle, or full tub
Mansard loft conversion: cost
- Starting at £40,000
The question of price is an important one, of course. It can be useful to compare it to other options, so you know what will work best for you. This variety will typically cost less than a hip-to-gable or L-shaped dormer, but more than a Velux or standard dormer project. So it sits in the middle of the range.
The final amount you pay will be determined by many factors, including:
It’s vital to align your budget with your expectations, and that’s where the pros come in. We can explain where to save money, what you don’t want to scrimp on, and how to maximise the potential of your roof space to balance cost with quality.

Frequently Asked Questions
The only difference with a mansard is that the slope across the face of the mansard will make the construction look softer from the outside. But it will sacrifice some head height compared to a dormer that is built vertical off of the back wall.
For a mansard loft conversion, around six to eight weeks is a typical timeframe for the the actual building work. However, the planning stage can also take a considerable amount of time, especially if planning permission is required.
The flat top of the mansard roof provides a very poor drainage system which could lead to leaks or even roof collapse. The complex design of the roof means that it takes longer for roofers to fix it, and most may not even be familiar with the design in the first place.
