Solar Havens of Toronto integrates thoughtful design and sustainability within the urban landscape of Toronto, Canada. The project focuses on energy efficiency while promoting community living through residential units that take advantage of the abundant sunlight during the colder months. Inspired by local Victorian townhouses, the design transforms them into wedge-shaped forms that maximize southern exposure, enhancing passive solar gain and reducing energy costs for residents.

Architectural Concept

The design emphasizes the importance of sunlight in providing warmth and light during winter. By arranging the units to face south, the layout improves natural heating and reduces the need for additional heating sources. This approach not only makes the buildings more comfortable but also allows for various configurations, whether in urban infill sites or when stacked in denser areas.

Materials and Construction

High-performance windows are a key feature of the project. They allow ample natural light while helping to retain heat within the units. This choice reflects a commitment to energy efficiency and sustainable practices. The use of a hybrid timber and steel construction method provides strength and durability while also being mindful of environmental impacts, as it can lessen waste produced during construction.

Community Engagement

Creating shared spaces is another important aspect of the design. Public circulation routes and communal areas within the mixed-use podium encourage residents to interact with one another. These spaces help cultivate a sense of community in the urban setting, making it easier for people to feel connected. Additionally, the flexibility of adjustable internal walls allows occupants to customize their living areas to suit their needs, accommodating different lifestyles and family structures.

Sustainability Features

Winter gardens are featured in the design, offering green spaces that remain usable even in cold weather. These gardens not only enhance the living experience but also promote biodiversity within the city. By integrating nature into everyday life, the project aims for a sustainable approach that resonates with the residents and the environment.

The blend of energy-efficient materials, adaptable designs, and a focus on community creates a living environment that addresses modern urban challenges while respecting the local context. Residents benefit from a space that is purposeful and connected to the world around them.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization.
