The Pierre Lassond Pavilion (the new building bears the name of the benefactor) is the fourth building of the Quebec Art Museum. All buildings are located in Battlefields Park (Champs-de-Bataille), but it is the OMA building that is "entrusted" to meet visitors entering the park, all other buildings are located further from the city blocks. This function of "meeting" architecture and nature is expressed by a cascade of three blocks, descending from Quebec to the park, from a smaller volume to a larger one. Upstairs are the halls for design and Eskimo art (42.5 mx 25 m), below is a permanent exhibition of contemporary and contemporary art (45 mx 35 m), and at the very bottom is a space for temporary exhibitions (50 mx 50 m).
The upper block forms a 20-meter console, under which the Great Hall is located - a multifunctional space facing the city with transparent facades (they are protected from the sun by glass lamellas). The walls of the exhibition spaces, on the other hand, are almost impenetrable: they consist of three layers of glass: fritted, corrugated and diffusing. A pattern is applied to them, echoing the farms placed on the perimeter of the building: they, having made up the supporting structure of the building, made it possible to make a powerful console and do without supports in the halls. A staircase is placed on the facade, another spiral staircase occupies the space of the atrium. The roof of the pavilion is designed as a series of green terraces suitable for a wide variety of events.
Next to the new building is the neo-Gothic church of Saint-Dominique. The Pierre Lassonda Pavilion is connected with the main building of the museum by a 130-meter walkway, in fact - a series of galleries. Such an extended space made it possible to exhibit there a 40-meter canvas from the collection of the museum "Dedication to Rosa Luxemburg" by Jean-Paul Riopel.
