October – November 2006. Paris was hit by downpours, numerous people injured, serious damage to the city’s structures and buildings. But the test was passed.

In the 20th Arrondissement, on the eleventh floor of a historic building, a glass and steel platform resisted the hardest test of all – Mother Nature – without any damage of infiltrations.
The theoretic laboratory tests into infiltrations of water, air and wind were effectively confirmed with great success against the terrible weather conditions.
The starting point was to extend a flat on the eleventh floor of a historic Paris building, by creating a glass attic using a totally metal structure: from the bearing frame, to the window and doorframes and the cladding entirely in steel.
The planning intention for the reconstruction, which expertly combines ancient and modern, was based on a single dominating factor: light and transparency. The constant dialogue between everyday home life and the city.
The residence develops over two floors divided between the previous floor, which is the large living area and the new sleeping-study area on the second floor.
It is on this floor that the city enters family life and thanks to the wide range of windows that have been installed: lifting-sliding, a large 5 wing window, lifting-tilting, internal partitions, all in AISI316L stainless steel with scotch brite type satin finish.
Given the thickness of the plate used for the profiles and the weight of the glass, the hinges were welded to the frames – the best solution always – so that the wing is a very strong, monolithic block.
Great attention was paid to the visual effect outwards throughout the project and when you walk around the large terrace, which has become a small Versailles garden, which creates the perimeter for the second floor of this glass box, you can see daily life carrying on inside, from the study, the lounge, the main bedroom and, thanks to the different types of windows, it becomes a visible part of the home: the French windows open to form a single attractive unity between inside and out through the specially studied doorsteps.
The large panoramic bedroom is another example: here the unusual corner frame opens right up, totally removing the upright as well as to give a breathtaking view of the Eiffel Tower. Special attention has been paid to finishing all the cladding sheet of stainless steel plate.
The sophisticated construction and installation is clearly shown in the details: the precise corners with no joins actually on the corner but moved to the side, to prevent the most critical points of infiltrations; around the edge of the roof there are two stainless steel bands: a wide one all around the edge and a second narrower one, coloured grey which forms the moulding around the crown.
Steel was the only choice in this extensive project: in such a special historic context inalterability, clean lines and, above all, strength were required: given the large glazed surfaces and narrow profiles, which had to leave the view totally free but which at such heights without any other buildings around to break the wind, the most total resistance to the violent wind and the weather, which is common at our latitude, had to be guaranteed.
