Located on the terrace on the 6th floor of the Centre Pompidou-Paris, this structure is intended to accommodate the team in charge of development of the new Centre Pompidou-Metz. It accommodates, in a temporary manner and for the duration of the project, the design team and elements associated with the presentation of the project to the public. Construction took place as a working studio project with international students during the Summer of 2004.
The structure forms a space 34.50m long and 4.40m wide. The entire space is covered in its entirety by a circular vault.
This vault, covered by a waterproof membrane and a system of panels, is made up of a system of cylindrical ribs. These are made of 29 semi-circular arches, equal throughout the length, and a network of cross-links. The arches are spaced every 1.20m. The ribs are made of cardboard tubes with a 120mm interior diameter and a 760mm exterior diameter. The entire structure, vault and base, is covered by an outer membrane of PTFE (polytetrafluoroethylene, meeting the requirements of fire resistance), which provides a weather seal.
The two end walls, gables, are made of a system of joinery, wood frame and fill. The temporary structure is designed as a continuous space. The various functional areas are defined by partitions made of high shelving. The space is divided successively into: a reception area, conference room, a work area, a relaxation area and a model workshop.
