Mansard loft conversion cost - mansard roof conversion in London

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:

Size
Design
Windows
Finish

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.

Maidenhead

The work that Fittra did for me was a full house renovation – this did not include any new build or extension work but it did include moving a number of internal load bearing walls and extending external openings to install large sliding doors. The work was reasonably complex structurally as the upper floor is steel beam and concrete block construction. Externally all windows and doors were changed, guttering and fascias were changed and a new tiled deck constructed to give an outside/inside feel. Internally, walls were moved, new door openings created or widened to give a modern open plan look and feel.Read More

Ealing

“Fittra completed a rear extension, loft conversion and full refurbishment of our house in Ealing late last year. This included new bathrooms, heating system (including underfloor heating), electrics and plumbing. When obtaining quotes, Fittra’s prices were in the middle of the three companies who came back to us with costs, but the fact that it was fully itemised (unlike the other costs we received) gave us piece of mind that we knew exactly what we were getting for our money. “Read More

“Can’t speak highly enough of Fittra and the job they did. They completed a rear extension, side return and loft extension and pretty much a full refurbishment of our house and garden in SW London. They not only did an incredible job, but they were also great to work with too. Vadym and Ivan’s team were incredibly efficient and hardworking and really amenable and collaborative. I have recommended them to a few friends subsequently, and will continue to do so.”

Hanwell, New build

Team at Fittra possesses all the attributes necessary to be an excellent contractor: they know their market extremely well; they are diligent, responsive, and yet very understanding with their clients. They are very professional and offer cost saving alternatives when possible. The thing that has impressed me the most is the professionalism, knowledge and helpfulness of all the workers.

“We did our house fully renovation last year July 2019 – December 2019 with Fittra. We are very pleased with the results – our new kitchen (rear extension with lantern roof light), loft conversion, hardwood flooring, underfloor heating, tiling and etc.. Ivan and his team are truly professional. They finished the job with timely manner and customer satisfaction. Their breakdown quotes are easy to understand and easy to work with. We are highly recommended for Ivan, Igor and the team. Great job!!!”
