SKYHIVE: THE TETRIS 2021 is located in San Francisco’s financial district, designed to meet the changing needs of office spaces in light of the recent global pandemic. The design focuses on integrating both collaborative and private working environments while promoting outdoor spaces that enhance user experience. The overall concept is based on stacking distinct volumes that fulfill specific functions, contributing to a varied and engaging urban profile.

Design Concept

The design of SKYHIVE is achieved through a careful arrangement of multiple vertical forms, each serving distinct purposes. The lower level primarily accommodates commercial activities, including a food court and parking facilities, which provide ease of access for everyone. Above this, a co-working level features flexible workspaces, conference rooms, and wellness areas, allowing for adaptability in how work is conducted.

Functional Allocation

The building’s structure efficiently organizes different functions across its height. Ground-level areas focus on commercial purposes. As one moves up, the design accommodates a mix of co-working spaces and small to large offices. This thoughtful layout supports a smooth flow of movement, enhancing collaboration and providing various work environments that cater to different requirements. It creates opportunities for spontaneous interactions among users throughout the building.

Terraces and Social Spaces

One key feature of the design is the green terraces strategically placed at various levels. These terraces provide social spaces for relaxation and interaction, blending nature into the urban environment. They create a balance, allowing users to engage with one another outside of formal work settings. The addition of greenery disrupts the building’s verticality and enhances users' overall comfort.

Façade and Materials

The building's façade is characterized by a perforated aluminum skin that helps manage sunlight and reduce glare. This choice not only addresses practical concerns but also shapes the building’s visual character. The three-dimensional aspect of the skin produces an interesting pattern of light and shadow on the surface, which adds depth to the building's overall look.

The interplay between the structured volumes and outdoor spaces creates an inviting atmosphere. The green terraces are not just decorative; they support a sense of community, allowing for both work and leisure.

`
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. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
