Biosphere

Perched at the top, Room 7 is organized around three fully glazed façades, offering direct views over Montréal, the St. Lawrence River, and Parc Jean-Drapeau. The design structures the space without compromising the panorama. A continuous built-in unit in semi-reflective steel runs along the façades, discreetly integrating technical functions—including services and heating—to maintain a constant focus on the landscape.

Walls and metallic surfaces, subtly reflective, capture variations in daylight throughout the day and visually extend the surrounding scenery into the interior. Overhead, a fine metal mesh ceiling references the dome’s industrial language while concealing technical equipment. The result is a clear, functional space where architecture recedes just enough to foreground the exhibition and the city beyond. Lighting, controlled by a time-based system, follows the natural cycle of daylight, shifting from cooler tones during the day to warmer atmospheres in the evening.

Room 6 is conceived as a museum space that can be transformed into a black box. The 3D view illustrates this potential, enabling the presentation of immersive experiences. Every detail is designed to integrate seamlessly and disappear, creating a neutral backdrop that meets museum standards while ensuring a high degree of flexibility for diverse content.

Patriarche’s interventions honor the original designers’ constructive intent while updating the Biosphere to meet contemporary needs. A precise and considered approach, embedded within a broader strategy of upgrading and enhancing the existing building.
