Westmount Square (French: Carré Westmount)[3] is a residential and office complex located in Westmount, Quebec, Canada. There are two residential apartment buildings and two office buildings. These towers sit atop an underground shopping centre consisting of thirty-five shops. It is located between Sainte Catherine Street West and De Maisonneuve Boulevard West and between Wood Avenue and Greene Avenue. It is connected to Place Alexis Nihon, Dawson College, and the Atwater Metro station by a tunnel.

Key Information

The complex was designed by architect Ludwig Mies van der Rohe in the International Style.[4][5] Construction began in 1964 and the complex opened on 13 December 1967. The exterior facade features curtain walls,[6] and is made of black anodized aluminium and smoked glass windows. It was modelled on Lake Shore Drive Apartments in Chicago.[7][8]

The office building, also known as Tower 1, has 22 floors and stands 83 metres (272 ft) tall. The other office building has 2 floors and is known as the Tower 4 Pavilion; it was formerly the Eastern Airlines Building. The two residential towers each have 21 floors, and stand 69 metres (226 ft) tall.[9]

Westmount Square's shopping concourse houses boutiques and art galleries, with about one-third of the space reserved for private for-profit health clinics.[10] Skylights were installed on the roof of the shopping concourse in 1990, which led to criticism among architectural preservationists.[11]

Westmount Square is a landmark modernist complex located in the affluent neighborhood of , , , renowned for its architecture designed by German-American architect and inaugurated on December 13, 1967. Comprising four high-rise towers—two residential and two commercial—built with black anodized aluminum framing and extensive glass facades, the ensemble rises atop a multi-level podium that includes an underground shopping concourse with 35 stores and direct tunnel access to the Atwater station on Montreal's Green Line metro. The project, initially proposed in 1964 after local plans were rejected, was constructed under Mies van der Rohe's supervision by firms including Greenspoon, Freedlander and Plachta & Kryton, at a cost of approximately $25 million, coinciding with Montreal's and marking a bold contrast to the surrounding Victorian-era architecture along Greene Avenue. The towers vary in height, with the tallest office building reaching 22 stories and 83 meters (272 feet), emphasizing Mies' principles of structural clarity, open plans, and through exposed steel, large windows, and paving in its original esplanade. As a integrating residential apartments, professional offices, retail, and public transit, Westmount Square has served as a prestigious hub for fashion, dining, medical, legal, and since its opening, owned and managed by Creccal Investments Ltd. since 2015. A significant in 1988 by new owners replaced the original elements with in outdoor areas and added skylights to the mall, though some critics noted it diminished the complex's original elegance. Despite these changes, Westmount Square remains a key example of mid-20th-century in , symbolizing urban innovation and enduring as a coveted in Montreal's architectural landscape.

History

Planning and Construction

The plans for Westmount Square were unveiled on November 17, 1964, by Lloyd N. Whitten, president of Westmount Centre Inc., the project's developer. This proposal followed the rejection of an initial plan by a local firm, after which developer Lloyd N. Whitten commissioned . The proposal outlined a mixed-use complex including two 21-story residential towers, a 21-story office building, a two-story , an underground , and parking facilities, aimed at generating revenue for the City of Westmount amid fiscal pressures. To prepare the 4.5-acre site bounded by Sainte-Catherine Street West, Greene Avenue, Western Avenue, and Wood Avenue, approximately 70 houses in the Lower neighborhood were demolished starting in , with minimal opposition from residents despite the scale of the clearance. This effort transformed a into space for high-density development, reflecting broader mid-20th-century trends in Montreal's expansion. Construction commenced in 1964 under the lead design of architect , whose International Style emphasized minimalist steel-and-glass structures, with on-site supervision by the Montreal firms Greenspoon, Freedlander, and Dunne, as well as Plachta & Kryton. Whitten, a developer associated with Trust Company, spearheaded the $25 million project through Westmount Centre Inc., marking one of Mies van der Rohe's few commissions in Canada. A primary challenge during planning and construction was securing approvals amid public resistance to the high-rise towers, which were seen as overpowering the low-rise character of surrounding Westmount. Integrating the underground shopping centre with the elevated towers required coordinated engineering to ensure structural stability and pedestrian connectivity, though specific technical hurdles were not widely documented beyond general urban integration concerns. Initial ownership rested with Westmount Centre Inc., transitioning later to other entities, including Creccal Investments Ltd., which acquired the commercial components in 2015.

Inauguration and Subsequent Developments

Westmount Square was officially inaugurated on December 13, 1967, marking the public debut of the mixed-use complex designed by . The opening highlighted its integration of residential, office, and commercial spaces connected by an underground concourse, positioning it as a pioneering example of urban development in . Upon its debut, Westmount Square received acclaim as a modern and sophisticated enhancement to the city's urban landscape, reflecting the era's embrace of architecture amid Montreal's mid-20th-century growth. This positive early reception underscored its role in blending high-end living with accessible amenities, drawing residents and visitors to the elevated plaza and towers overlooking the surrounding neighborhood. Ownership of the commercial components transitioned to Creccal Investments Ltd. in 2015, following a sale from Elad Canada, with the company assuming responsibility for ongoing management and preservation efforts. Creccal, a Montreal-based firm established in 1977, has since overseen maintenance to uphold the site's modernist character while adapting to contemporary needs. A significant post-opening development occurred in the late and early , when renovations addressed the shopping concourse's lighting issues. In 1988, new owners initiated updates that included replacing the original paving with , sparking the first major heritage preservation battle in over modernist structures. By 1990, amid public controversy, skylights were added to the concourse roof to improve natural illumination, following advocacy from preservationists including , who pushed for sensitivity to Mies van der Rohe's original design vision. These changes, while debated, contributed to updated heritage laws in the province and minor ongoing maintenance to sustain the complex's structural integrity and aesthetic coherence.

Architecture

Design Principles and Influences

Westmount Square embodies the of modernism, a movement pioneered by that prioritizes minimalism, open floor plans, and the honest expression of structural elements without ornamental excess. This approach is evident in the complex's rectilinear forms, expansive glass facades, and skeletal steel framework, which emphasize volume and regularity over mass or decoration, allowing for fluid interior spaces that adapt to diverse residential and commercial uses. The design draws direct inspiration from Mies van der Rohe's earlier 860–880 Lake Shore Drive Apartments in (1948–1951), which established his signature high-rise typology of twin towers on with curtain-wall enclosures. At Westmount Square, this model is adapted to a dense urban mixed-use setting, scaling up the concept to incorporate office, residential, and retail functions while maintaining the original's emphasis on elevated volumes that promote transparency and visual continuity between building and plaza. Central to the project is Mies' philosophy of "less is more," which manifests in a focus on verticality and symmetry to create a sense of order and elevation, alongside the seamless integration of interior and exterior spaces through large-scale glazing that blurs boundaries and invites natural light into the core. As lead architect, Mies collaborated with the Montreal firm Greenspoon, Freedlander & Dunne to tailor the design to local zoning and climatic conditions, ensuring structural integrity and site-specific adaptations without compromising the universalist ideals of modernism. Constructed and inaugurated in 1967 amid Montreal's hosting of , Westmount Square exemplifies mid-20th-century urban modernism in , a period when the country embraced sleek, functional architecture to symbolize progress and international sophistication. The complex's austere elegance aligned with the exposition's showcase of innovative design, contributing to a broader wave of modernist developments that redefined Canadian cities during the nation's centennial celebrations.

The structural core of the complex relies on a to support the high-rise towers, enabling flexible interior layouts and the integration of open spaces. Exposed structural elements in select areas underscore the precision, aligning with the design's focus on structural honesty. Complementing this, the low-rise shopping concourse is constructed with a base, providing stability for the underground commercial facilities and connecting the towers seamlessly below ground level. The choice of anodized aluminum for the exterior not only contributes to the visual uniformity but also ensures low and resilience against Montreal's variable , including cold winters and humidity, supporting the complex's long-term integrity since its completion in 1967. The total floor area across the towers and concourse spans approximately 30,000 , encompassing residential, , and retail uses.
