Rising at the edge of downtown in Montreal’s Quartier des Gares, 900 Saint-Jacques offers a measured and contextually aware response to the pressures of high-density urban living. Built on a site long perceived as leftover infrastructure land—caught between rail corridors and the Ville-Marie Expressway—the 63-storey tower reframes this condition as an opportunity, establishing a cohesive and liveable vertical neighbourhood within a challenging urban landscape.

The mixed-use program is ambitious in both scale and intent. Four levels of underground parking support a 12-storey Moxy hotel, topped by approximately 700 rental residential units distributed across 48 storeys. As Montreal continues to balance heritage, housing demand, and ecological transition, 900 Saint-Jacques demonstrates how vertical development can meaningfully engage the city’s past while accommodating contemporary lifestyles.

In contrast to the city’s growing field of glass residential towers, the building’s precast concrete envelope asserts a distinctly Montreal identity. Drawing inspiration from Old Montreal, Place Ville-Marie, the Sun Life Building, and even the Olympic Park, the façade reinterprets the city’s mineral architectural language in a contemporary way.

Sculpted precast panels—composed of interwoven threads and cruciform motifs—give the tower a tactile, textile-like expression. Through careful articulation, false joints, open corners, and panels that extend beyond their nominal modules, the façade blurs conventional boundaries between elements, creating a sense of continuity and lightness despite its material weight. Solar orientation further animates the surface, revealing subtle variations in relief throughout the day, while transparent volumes punctuate the massing to expose moments of social life within.

This approach was recognized with a 2025 Canadian Architect Awards of Excellence, citing the project’s architectural clarity and technical mastery—particularly its innovative use of precast concrete at scale.

The tower’s massing is organized into three distinct layers, each aligned with a different urban scale and landscape condition: a transparent base, a planted podium, and a crowned tower.

At street level, a highly glazed envelope activates the public realm, framing a garden connected to a restaurant terrace and adjacent cycling infrastructure—supporting the greening ambitions of the Quartier des Gares PPU. Above, the podium introduces textured concrete panels and landscaped terraces, forming a suspended garden that mediates between the city and the residential tower. At the top, a rooftop green space is framed by oversized façade openings, offering panoramic views toward Mount Royal and reinforcing the building’s vertical dialogue with Montreal’s topography.

Rather than treating amenities as an afterthought, 900 Saint-Jacques places collective life at the core of its residential concept. A distributed network of shared spaces—terraces, gardens, a restaurant, community rooms, coworking areas, shared kitchens, and relaxation zones—extends daily life beyond the private unit.

These amenities are accessible to both residents and hotel guests, encouraging overlap and social interaction throughout the day and evening. The result is a model of vertical living that prioritizes experience, connection, and flexibility over isolation.

Sustainability at 900 Saint-Jacques is addressed through both environmental performance and long-term livability. The high-performance envelope, paired with advanced electromechanical systems, exceeds baseline energy standards and aligns with LEED-type certification principles. Optimized window-to-wall ratios, locally sourced materials, water-efficiency strategies, and high-efficiency lighting collectively reduce the project’s environmental footprint.

Notably, the precast concrete façade improves winter energy performance by approximately 25% compared to a conventional glass envelope—underscoring the environmental value of material choice in Montreal’s climate.

Socially, the residential mix emphasizes diversity and adaptability. An increased proportion of family-sized units—including three-bedroom and flexible layouts—supports long-term urban living, while compact units offer more accessible entry points to downtown housing. These smaller dwellings are balanced by the quality and generosity of shared spaces, reinforcing a holistic approach to density.

900 Saint-Jacques ultimately positions itself as more than a residential tower—it is a carefully calibrated urban system, weaving together heritage, infrastructure, community, and performance into a distinctly Montreal expression of contemporary city-making.
