Three distinct apartment types cater to diverse living arrangements and community needs.

Grape House acts as a thoughtful solution for affordable housing in Toronto, blending function with an innovative design inspired by a bunch of grapes. Its modular structure is adaptable, allowing residents to customize their living spaces while promoting a sense of community. The overall concept focuses on creating a harmonious environment that nurtures relationships among residents.

Conceptual Framework

At the heart of Grape House is a system built on steel pillars, which serve as the framework for its modular design. This choice provides flexibility in unit configurations, making it possible to create various living arrangements. The layout encourages vertical interactions, connecting apartments to shared green spaces. This thoughtful arrangement not only enhances privacy but also fosters a community-oriented atmosphere.

Privacy and Green Integration

Key features of Grape House include green buffer zones placed between the living units. These areas not only protect against noise but also contribute to cooling the surroundings during warm weather. Another interesting aspect is the design of flat roofs, where one unit's rooftop garden is accessible to neighbors. This collaboration reinforces the building’s commitment to sustainable living and thermal efficiency, combining plant life with residential space.

Sustainability and Urban Connectivity

The project places a strong emphasis on sustainability with plans to increase greenery significantly. This includes the introduction of agricultural gardens and a variety of plants such as bamboo, which together create a vibrant and lush environment. By encouraging residents to rely less on cars and utilize the nearby public transportation system, the design aims to maintain a reduced carbon footprint while integrating seamlessly into the urban landscape.

Residential Diversity

Grape House accommodates various lifestyles by offering three types of apartments. There is a compact 16 m² unit for students, a 32 m² unit suitable for two people, and a larger 64 m² unit designed for small families. This range ensures that the building meets different living needs and promotes inclusivity among residents.

The building’s façade showcases different depths and textures, creating a dynamic appearance that changes with the light throughout the day. This thoughtful detail enhances the visual appeal while contributing to the architectural identity of Grape House.

Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
