AAD : Lycée d'hôtellerie et de tourisme de Guyancourt

In Guyancourt (78), the agency Architectures Anne Démians rehabilitates a high school of hotel and tourism. In terms of both form and form, this major intervention aims at reconsidering a complex architecture inherited from the 1970 years and smoothing out the different stigmas and the resulting modalatures, in order to better reveal the original volumetry: that of a steamer.

The history of this project begins in 2005, when a contest is launched by the region of Île-de-France to revive the high school of hotel and tourism of Guyancourt, the largest of France, to improve Its aesthetics and its functionality. It took twelve years of patience and hard work to get the equipment out of new clothes. In addition to the multiple administrative pitfalls that slowed down the construction work in two main sections, the deep restructuring took place in busy ... busy, with no less 900 permanent students - including 150 internal -, and 700 additional within the framework Of continuous formations, distributed in a single building of 30 000 square meters, divided into nine floors.

At the heart of the redevelopment: an entrance hall crossing in triple height with airs of Roman agora, which allows the place to find lost centrality, the old building with no less than 14 different access points. This main square now connects the street to the north and the Mall of the Willows, a pedestrian walkway planted in the south, which did not communicate in advance. To the east, practice rooms have been reorganized and brought together for obvious use and program readability: the kitchens, offices and restaurant follow one another from north to south on one level. In double-height, these firsts benefit from an indirect and subdued zenith light. The dishes are prepared before being trained and then brought to the dining room where visitors can enjoy tastings in a reception area divided into two rooms marked by large bay windows. With their imposing framework, the latter are a benchmark for the public, who can come to taste the preparations made by the residents. They are also integrated in a stainless steel volume passing through and through the imposing ground floor. This intervention on the facades and more generally the work of isolation from the outside, allowed to aesthetically smooth the whole which thus regains its original volumetry, that of a steamer designed by the architect Jean Monge in the years 1970 and delivered in 1981.

The spatial recomposition is not only horizontal but also vertical with, above the teaching pieces previously mentioned, spaces of encounter such as the self and an outdoor patio - where lunch together pupils and teachers - all overhung by An internship divided into rooms of 4, 6 and 8 people.

A total work, therefore, which allows to weave a lost link between the building and its urban context, but also between the interior spaces themselves.
