Here's some more information from Tigg Coll Architects:


Designed for a young client who wanted to convert his standard maisonette in Kensington, London, into a contemporary loft apartment for entertaining.

All the internal partitions, floors and existing staircase of this triplex apartment were removed, presenting a blank canvas of the existing structure.

The new staircase is cantilevered off an exposed brick clad wall imported from Denmark and runs the full height of the house, concealing the structural steelwork behind.

The oak-clad open treads and cantilevered glass balustrade allow light to flood down from the rooflight high above, as well as allowing light to filter through from both the front and rear windows.

The previously small living spaces are now open-plan with the kitchen at the heart, between the reception and mezzanine dining area.

The purposefully designed double-sided wine rack and openings in the staircase allow a separation of space yet also a connection, with glimpses through to the spaces beyond and above.

On the upper floor, the existing double butterfly roof was exposed and new ceilings installed to follow these lines, allowing ceiling heights throughout to be maximised and sculptural.

The new rooflight nestles in the roof pitch of the resultant space over the staircase.

    Why is it called butterfly loft?

      It's because of the shape of the loft, which you can see in the section.

    I am trying something similiar for my own residence but struggling with building control regulations. How it is solved here? Are any fire curtains used?
