The Projet Triangle is primarily perceived on the metropolitan scale of the city of Paris. Its elevated stature will lend major visibility to the Porte de Versailles and the Parc des Expositions site within the overall conurbation. It will also permit its integration in the system of axes and perspectives that constitute the urban fabric of Paris. On the scale of the Porte de Versailles site, the Projet Triangle will also play a significant role in the reorganisation of flows and perception of urban space. The Parc des Expositions site currently forms a break between the Haussmanian fabric of the15th district of Paris and the communities of Issy-les-Moulineaux and Vanves, emphasised by the visual impact of the peripheral boulevard.
The Triangle is conceived as a piece of the city that could be pivoted and positioned vertically. It is carved by a network of vertical and horizontal traffic flows of variable capacities and speeds. Like the boulevards, streets and more intimate passages of a city, these traffic flows carve the construction into islets of varying shapes and sizes. This evocation of the urban fabric of Paris, at once classic and coherent in its entirety and varied and intriguing in its details, is encountered in the façade of the Triangle. Like that of a classical building, this one features two levels of interpretation: an easily recognisable overall form and a fine, crystalline silhouette of its façade which allows it to be perceived variously. This vertical city district stands in close relation to its environment and is accessible to a highly diverse public. Taking up the analogy of urban squares, it offers each individual the opportunity to enter a complex of spaces open to all on its levels.
The base of the project is open to all, from the square of the Porte de Versailles and along the avenue Ernest Renan which regains the appearance of a Parisian street, with its shops and restaurants. An elevated square, on level with the roofs of Paris, will offer everyone a unique view of the district and the whole city. This visit might then be extended in the higher reaches of the Triangle, from where the entire metropolis can be discovered.
