Apartment Madeleine by Ateliers Michael Herrman.
“Sitting on the top two floors by Paris’s Place de la Madeleine, this 140 m2 (1500 ft2) residence was created by unifying 12 maids’ rooms on two levels. The result is a three bedroom duplex apartment that both preserves the character of the 200 year-old building in which it is located, yet is a uniquely loft-style space in the heart of Paris. The apartment is based upon the concept of a museum: the original limestone walls and oak beams have been excavated and displayed with archaeological precision. The addition of a glass floor and walls allows each room to retain a powerful sense of openness, to be visually connected with one another and with the views of the sky and rooftops of Paris.
