Situated in Place de la Madeleine in Paris, this amazing apartment is a really rare thing to find. Ateliers Michael Herman have done an incredible job in bringing back the 200 year-old structure of the building while transforming the place in a complementary living space for a young family. The apartment occupies the top two floors of a residence that used to be made up by 12 maids’ rooms. With archaeological precision, the original limestone walls and oak beams have been brought back to life, and combined with modern day materials such as glass and metal to obtain a surprising effect. The main characteristic of the design is the extensive use of glass, both in structural elements and in furnishings. The most interesting feature is the glass floor that separates the two floors and allows for the volumes to take incredible dimensions in height. There is a skillful mix of transparent glass and mirrored surfaces which multiply the space infinite times. As the footprint is quite small, the designers have enhanced the value of the heights by using vertical walls seven meters high. On the other side of this glass facade there is a small patio which seems to derive from the living room thanks to the use of the same hexagonal floor tiles both inside and outside. The presence of an antique marble fireplace and of a chandelier make this patio look like another room of the house.
