The firm's portfolio ranges from single family homes, such as Résidence dans les Laurentides, to major institutional buildings, such as the UBC Faculty of Pharmaceutical Sciences, the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, and the Communication, Culture and Technology Building at University of Toronto Mississauga.

[5] As of March 2020,[update] the firm comprises a small team of fewer than 20, with Gilles Saucier as the Design Partner and André Perrotte as the Project Architect.

[2][non-primary source needed][8] Their designs often depict and capture the nature and mood of what is happening inside, through shapes, materials, and colours.

[2][8] Gilles Saucier (born 22, December, 1959 in Ste-Françoise, Quebec) grew up in the countryside, interested and inspired by the nature and trees surrounding him.

[14] André Perrotte (born 6, June, 1959 in Ste-Foy, QC) received his Bachelor of Architecture at Laval University in Quebec City in 1982.

The Saint-Laurent Sports Complex is located between the character neutral and horizontally formed Émile Legault School and Raymond Bourque Arena.

The Sports Complex design had to physically and visually connect with Marcel Laurin Park (north of the site), and the green band running along Thimens Boulevard.

The roof’s interlaced beams appear erratic, suspended over the site; however, its density is determined by the areas where more structural support is needed.

[17][18] 2012, Montreal, Canada The Anne-Marie Edward Science Building is in the John Abbot College campus, in a rural setting along Lake Saint-Louis.

Inside, the architects designed the central staircase to be a sculptural and abstracted version of a tree, with branches of stairs spanning into its laboratories, classrooms, and offices.

The building, formally known as a warehouse, was restored half a century ago due to fire damage and now houses an urban spa on its ground level.

[23][24] The spaces were inspired by the duality of the hot and cold phenomena, with white, glacial volumes contrasting the warmth radiating off the volcanic rocks.

Erosion caused the volumes to drift to the side; formally parallel to the residence, the guesthouse slid westwards, separating from the main mass of the home.

The anodize aluminium south façade contains an abstract pattern of punched windows and polished stainless-steel mechanical grills, reflecting the enigmatic subject of physics.

The main hall provides direct access to all programs, with vertical circulation from the concrete staircases descending along one side of the atrium.

The building is a place of occupancy, adjacency, and transition, as it creates a linear public circulation space between the Student Centre and the Library.

Conceptual strands of landscape are vertically woven throughout the structure, connecting students and spaces together through bridges, ramps, platforms, and staircases.

The pavilion’s exterior spaces are integrated into the surrounding environment through the minimal design of vertical surfaces, leaving an open terrain between the building and the site.

[30][31] 1997, Montreal, Canada Built into the gap of two existing buildings, the design of the Cinémathèque Quebecoise demonstrates the relationship between the old and new, interior and exterior, and actor and audience.

[32] The “light box” entrance from de Maisonneuve Boulevard explores the qualities of film through its light-weight steel frame structure and illumination.

A gridded glazed screen cantilevers over the sidewalk, while laterally extending to the restored, historical, stone and brick façade of its neighbouring building.
