The Louis Vuitton Foundation by Frank Gehry (2014) is gallery of contemporary art located adjacent to the Bois de Boulogne in Paris was opened in October 2014. Gehry described his architecture as inspired by the glass Grand Palais of the 1900 Paris Exposition and by the enormous glass greenhouses of the Jardin des Serres d'Auteuil near the park, built by Jean-Camille Formigé in 1894–95. Gehry had to work within strict height and volume restrictions, which required any part of the building over two stories to be made of glass. Because of the height limits, the building is low, sited in an artificial lake with water cascading beneath the building. The interior gallery structures are covered in a white fiber-reinforced concrete called Ductal. Similar in concept to Gehry's Walt Disney Concert Hall, the building is wrapped in curving glass panels resembling sails inflated by the wind. The glass "Sails" sails are made of 3,584 laminated glass panels, each one a different shape, specially curved for its place in the design. Inside the sails is a cluster of two-story towers containing 11 galleries of different sizes, with flower garden terraces, and rooftop spaces for displays.
