RUE SAINT-GUILLAUME In the heart of Saint-Germain-des-Prés, rue Saint Guillaume, lies a unique place which has seen, on two occasions, the architectural creation of the 20th century transform an 18th century mansion located between the courtyard and garden: - in the 1930s, by the insertion of the Glass House, a major work of the architect and furniture designer, Pierre Chareau, and listed as a historic monument - in the 1950s, by the transformation of the two upper floors which overlook the Glass House in this apartment, object of the sale. This place steeped in history, hidden from view and distributed on two levels like a house on the roof of 347.69 m2 Carrez law with terrace, offers a unique view of the garden of its famous neighbor and has retained all its features. Decorative elements characteristic of the 1950s. Remarkable floor plan, perfectly modular. Sun and absolute calm. A staircase signed Paul Nelson and a private elevator serve said apartment from the courtyard of the building.
