SITE / The Covered Evolutionary Sports Complex, built between 1977 and 1988, is recognizable by its metal framework and truss beam structures inherited from constructions of the 1970s/80s. The current sports complex is poorly regarded. It is characterized by a heterogeneous juxtaposition of aging facilities, featuring an industrial metallic aesthetic and offering few openings, which makes it unwelcoming. SUBJECT / Attempting a balancing act: preserving existing structures as much as possible while completely changing the appearance and functioning of the facility to make the organization clear, both in plan and in volume. We start from the premise that the building is a resource, a sum of architectural elements and materials already in place that will be reused. NEW IMAGE / The framework is preserved but unified around a new envelope, made of matte Moka cladding echoing the golden stones of Mont d’Or. The two sports halls are simplified, their parapets raised to form a straight edge and hide the new roof insulation. These two high volumes are complemented by two low volumes. They will group all the rooms serving the sports halls. The first, to the south of the multipurpose sports hall, reuses the structures of the existing construction. The second is built to the north of the gymnastics hall. These two volumes, covered with a gently sloping roof, emphasize a low edge at the pedestrian scale and mark the entrances to the facility.

REVERSIBILITY / The interior organization reflects this additive construction. The two sports halls have no mutual visibility, and the facility suffers from a lack of unity. The symmetry of the two reconstructed low volumes plays on this duality to offer reversibility between the north and the south, with the presence of two halls. In the north, a main hall ensures the connection to the school and links the facility to the outdoor field. In the south, a secondary hall provides additional reception possibilities during competitions and allows direct access to the club changing rooms. TRANSPARENCY AND OPENNESS / The rehabilitation is an opportunity to create a unified facility, whose experience is shared by all users. It is possible to physically cross the sports complex from north to south and to visually encompass both halls from east to west. These visual crossings are also reflected on the façade, creating views to the surrounding environment and allowing the activity inside the facility to be seen from the outside. INTERIOR ATMOSPHERES / The raw materials and galvanized steel give way to colored structures corresponding to each part of the complex. All technical elements are left exposed. Adjusted and designed, they become architectural elements. Each sports hall corresponds to a color: red for the gymnastics hall, green for the multisport hall. The gymnastics center is associated with red, highlighting the historical frame of the hall and creating structural legibility of the space. The multisport center is associated with green, forming a continuous layer within this space.

The gymnastics center is associated with red, the first color that humans mastered, both in painting and dyeing. The color fills this wing of the building: in touches of paint, red highlights the historic framework of the hall as well as the various ducts and pipes, offering the user a structural readability of the space and its architecture. The aerial presence of the color is also a nod to gymnastics, which occupies the airspace through its practice. This highlights the historic framework of the hall, creating a structural readability of the space. The multisport center is associated with the color green, forming a layer in this space. GREEN The multisport center is associated with the color green, a color that was long difficult to produce or fix, yet is naturally all around us in vegetation. Green is also the complementary color to red. Unlike the gymnastics center, the color occupies the lower part of the hall's volume, creating on the ground a layer in which players interact with the color.

In order to face increasingly frequent heatwave phenomena, the new sports complex is equipped with articulated transoms on facades associated with automated roof openings, allowing the heat accumulated during the day to be evacuated at night during the summer months. This natural airflow system contributes to the coexistence of the building with its environment.
