Concept
Seen from above, the external spaces of the project form a continuity with the gardens which surround the site. They play a role in the every-day functioning of the building, and, at a larger scale, in promoting the biodiversity of the urban island where the site is located. In the manner of a Russian doll, the smaller patio gardens nestle within larger gardens, which are, themselves, contained within the network of gardens surrounding the site, and overlooked by planted balconies and roof terraces.
This composition, based on a continuous swathe of green spaces, promotes the natural and biological communication between gardens and offers a broader perception of nature viewed from within the site as well as from neighbouring buildings. The different planted terraces, patios, roof gardens and other external planted areas developed in the project are envisaged as spaces for the use and benefit of all users alike.
Program
The restaurant patios
The first level below ground receives daylight from the garden patios which are designed as an extension of the adjoining restaurant areas, and these shaded gardens, acting as light-wells, provide places of cool relief during hot weather. Raised-bed planters define paved areas which act as alcoves and mirror similar forms within the adjacent hall, blurring the limit between inside and outside.
The gardens
The gardens are designed as an extension of the inside spaces, offering the possibility of working and holding meetings in the open air. The depth of soil, from 50cm to 1m, allows rich and varied planting of sufficient size to structure these areas. Intermittent lines of planting separate smaller paved areas with increased privacy so that several groups can hold discussions or meetings without disturbing one another.
Eighth floor terraces
The roof level terraces provide an exceptional panorama over Paris, the Avenue Général de Gaulle, La Défense and the Arc de Triomphe on one side, and the Fondation Louis Vuitton and Mont Valérien on the other. The meeting rooms at this upper level benefit from the adjacent paved terraces for open-air meetings or receptions, and raised planters articulate the space into individual ‘rooms’.
