The Guillaume Tirel High School for teaching the hotel trade is located on Paris’ Boulevard Raspail in the Montparnasse district. The building is composed of two main volumes, i.e. a crystalline base that adheres strictly to the line of the street and a central building that is adapted to specific situations. The autonomy of the two volumes has made it possible to create a playground in the interface on the second floor.
The brief contains the following: training kitchens and an hotel, a second students’ restaurant, unadorned classrooms, administrative offices, a large lecture hall and dormitory quarters. Architectural unity was needed to house such diversity. This unity has been achieved by using a weight-carrying pattern formed by prefabricated concrete and stone portal frames. This repetitive series makes it possible to create a continuous envelope with the same openings whatever use is made of the space.
