### Project Overview

Located at 400 South Lanza Street in San Jose, California, Interchange encompasses both interior and exterior spaces totaling 8,070 square meters. The design team, consisting of Ilke Iliev, Chris Donatello, and Anthony Mull, has created a structure that aims to embody the interconnectedness of contemporary urban life, particularly within the context of San Jose's vibrant technological landscape.

### Aesthetic and Spatial Strategy

Interchange features a unique angular form that conveys movement and dynamism, reflecting the innovative spirit of Silicon Valley. The design integrates sharply inclined planes that enhance visual interest and suggest fluidity. The project incorporates significant architectural elements, including a prominent vertical tower that symbolizes connectivity and offers panoramic views of the surroundings. Tube and bridge structures within the design serve as both pedestrian pathways and aesthetic components, facilitating movement throughout the building and contributing to its overall narrative.

### Materiality and Sustainability

The selection of materials is a key aspect of the project's identity. Reinforced concrete provides the structural framework for the building, while floor-to-ceiling glass enhances natural light access and visual connections to the environment. Aluminum panels lend a contemporary aesthetic, and the incorporation of recycled wood in select interior spaces adds warmth and comfort to the design. The landscaping surrounding the structure features native plant species that minimize water use and promote biodiversity, underscoring the project's commitment to sustainable practices.

### Community Engagement and Interior Layout

The interior layout focuses on fostering community interaction through multi-functional spaces suitable for various activities, from exhibitions to social gatherings. Open areas are prioritized, enabling free movement and encouraging occupants to engage with one another. Innovative vertical circulation elements, such as escalators and staircases, enhance connectivity between levels, making the building a central hub for social engagement. By situating itself at a major transit junction, Interchange improves accessibility and supports economic activity in the region, reinforcing its role as a vital communal asset within San Jose's urban fabric.

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.
