Balboa Valley Housing is a residential development located in San Francisco, designed to improve accessibility and foster a sense of community. It focuses on combining homes, shops, and public areas into one cohesive environment. This approach supports local residents while emphasizing sustainable living and transit-oriented planning. The project aims to create a welcoming atmosphere where people can interact and connect with their surroundings.

Design Concept

The design emphasizes the creation of green spaces that flow through the building. Cascading terraces are a key element, reflecting the natural hills of San Francisco. These terraces enhance the view while providing additional outdoor space for residents and visitors. They serve as areas for relaxation and social interaction, allowing people to enjoy the city’s pleasant climate.

Structural Framework

A concrete platform forms the foundation of the residential units. This strong framework allows the development to span existing transportation routes. By elevating the living spaces, the design improves safety and access for walkers and cyclists. It connects the housing directly to the Balboa Park BART Station, making public transport easy to reach and reducing reliance on cars.

Sustainability Initiatives

Environmental awareness is a significant aspect of the development. The design includes guidelines for “Green Zoning,” which promotes biodiversity and provides more green areas for residents. The project also integrates shared utilities and energy-saving systems, like rainwater recycling, to minimize its ecological impact. These features support a more sustainable lifestyle for residents.

Community-Oriented Spaces

The project includes various public facilities, such as markets, shops, and places for learning. Integrating these spaces into the design encourages people to come together and engage with one another. This approach helps build a strong community feel and addresses the needs of local residents. The development aims to create not just homes, but also a lively neighborhood where people can thrive.

Common areas and terraces offer residents the opportunity to connect with nature and each other. These spaces foster a sense of belonging and encourage outdoor activities, enhancing the living experience of those who call Balboa Valley Housing home. The focus on community and sustainability is evident in every aspect of the design, contributing to a more vibrant urban environment.

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.
