A smart way to make the most of your home’s unused attic space is to convert it into useful rooms like bedrooms, offices, or areas for play and relaxing. Building up is often the best way to add value and comfort to your home in London, where ground-level room is hard to come by.
As more and more people need more living room, they are creatively adding on to their homes by going up. A very popular choice is the Mansard loft conversion, which stands out for its beautiful design and useful extra room.
How do you turn a mansard into a loft?
The roof structure is changed during a mansard loft conversion, so that one or both sides become almost straight up. Most of the time, the back roof is raised to about 72 degrees, which gives you more legroom and floor space. People often see this kind of change in cities and old homes, but it can also work in many modern homes.
This makes an extension that feels like a natural part of your home instead of an addition. It’s large and flexible.
Why Choose to Turn a Mansard into a Loft?
There are several reasons why people choose to convert their mansard to a loft over other types of lofts:
- Maximum Space: Compared to dormer or Velux changes, this one gives you the most space.
- Price increase: Adding a mansard to your home can increase the price by 20%.
- Flexible use: It can be used in many ways, including an office, an extra bedroom, a master suite or even a studio apartment.
- Beautiful design: Fast edges and dorms give your home a classic look that will never go out of style.
- Benefits of plan permit: In many places, especially London, lack of conversions are allowed when fits with the rest of the architecture.

Benefits of Converting a Mansard into a Loft:

1. Add More Living Space:
With a mansard loft, you can make any room you want, from a new bedroom to a luxury master suite with en suite to a home office.
2. Make your home more valuable:
Buyers are more interested in homes that have been converted from lofts, especially those with mansards. In this way, it’s both a long-term investment and a better way to live.
3. Enjoy the sunlight:
Because they often have skylights or dormer windows, mansard lofts feel warmer and friendlier than other builds.
4. Design that can be changed:
You can change everything about the plan to fit your needs, from the flooring to the built-in storage.
5. Make your home look better:
A mansard roof can give your home a classic, classy look that goes well with other buildings in the area.
Do you need permission to plan?
Most mansard loft conversions need permission from the city because they change the roof’s shape so much. Easy loft changes don’t work this way. We at The Loft Worm handle the whole planning process and make sure that your project meets all the rules set by the building control and local meeting.
How long does converting a mansard into a loft takes?
It takes about 8 to 12 weeks on average to convert a mansard, but it depends on how big and complicated it is. The schedule can also be changed by things like getting planning permission, bad weather, and adding more design features.
What it costs to turn a mansard into a loft?

The price can change based on your home and the details you pick. A mansard conversion generally costs more than a Velux or dormer conversion, but it gives you the most useful space and raises the value of your home the most. It’s like putting money into both your home and your quality of life.
