The Design

About Urban Symbiosis Mix Use Towers

Urban Symbiosis is a mixed use supertall development above the 7 Train station in New York City, integrating condos, serviced apartments, and offices. Celebrating the great underground, the subway entrance is placed at the center, offering natural light and 24/7 public access. The design optimizes energy loads by combining office and residential programs, reducing grid pressure.

Design Interview

What is the main principle, idea and inspiration behind your design?

The core principle behind Urban Symbiosis is to foster a mutually beneficial relationship between architecture, nature, and urban life—an ecosystem where built and organic environments don’t just coexist, but actively support and enhance one another. The idea was inspired by biological symbiosis—relationships in nature where different organisms live in close, often interdependent proximity. I was fascinated by how such models of coexistence can be transposed into urban design, especially in rapidly urbanizing cities where the clash between natural and artificial systems is often stark. My aim was to shift the paradigm from separation and domination to integration and reciprocity, embedding ideas of environmental stewardship and collective well-being into the very bones of the project.

What has been your main focus in designing this work? Especially what did you want to achieve?

The central focus was to dissolve the boundaries between infrastructure, landscape, and public life. I wanted to create a spatial narrative where technology, community, and ecology are interwoven seamlessly. More than just designing a functional piece of urban fabric, I wanted Urban Symbiosis to provoke a deeper reflection on how cities are structured, how we live within them, and how architecture can become a regenerative force rather than a consumptive one. I was also intent on ensuring that this design would remain adaptable—able to change with time, seasons, and urban needs—without losing its essence. My hope was that the project would serve as a catalyst for dialogue on future urbanism and help people emotionally reconnect with their environment.

What are your future plans for this award winning design?

The recognition of this project has opened new avenues for further development. I am currently in discussions with several municipalities and private developers interested in adapting Urban Symbiosis to their local contexts. The design is modular by intention, so we plan to tailor it to different scales and climates, whether it’s in a dense megacity or a growing secondary city. I also envision the project being part of a broader research initiative—a platform that continuously evolves by integrating feedback from users, ecological data, and new technological innovations. Eventually, I’d like to publish a monograph that details its evolution, theoretical framework, and implementation, serving both as a case study and a manifesto for regenerative urban design.

Grand Interview

Your innovative approach to horizontally splitting the Urban Symbiosis Mix Use Towers into residential and office spaces represents a significant departure from traditional vertical stacking - could you elaborate on how this architectural decision enhances both energy efficiency and community interaction?

The decision to horizontally divide the tower—placing residential and office programs in two separate volumes joined by a shared core—emerged from a desire to rethink the conventional logic of mixed-use skyscrapers. Typically, these programs are vertically stacked, with offices occupying the lower half and residences above. While this stratification is efficient in zoning terms, it often isolates communities and exacerbates the disconnection between different user groups. By placing these two functions side by side and bridging them with shared infrastructure, I was able to create opportunities for real social overlap, not just physical adjacency.From an environmental standpoint, this arrangement also enhances energy performance. Residential and office uses have different peak energy demands—offices peak during the day, while residential peaks in the evening. By aligning these contrasting temporal patterns horizontally and sharing mechanical systems and façade strategies between the two, I was able to smooth out energy demand cycles and reduce the overall load. This results in a more balanced, efficient use of building systems and opens up new possibilities for shared energy storage and passive design.

The integration of the subway entrance at the center of Urban Symbiosis Mix Use Towers creates a unique celebration of public transportation - what inspired this bold design choice, and how does it reflect your vision for the future of urban connectivity?

The subway station is not an afterthought in Urban Symbiosis—it is the heart of the project. In many cities, infrastructure is hidden or relegated to the background, treated more as a service node than a civic space. I wanted to challenge this paradigm by celebrating public transportation as the central connective tissue of urban life. Embedding the subway entrance directly between the two programmatic towers is a symbolic and spatial gesture that reflects our belief in transit-oriented development and urban equity.This move ensures seamless integration between daily life and mass mobility. Commuters, residents, and workers intersect at this point of convergence, creating spontaneous urban interactions. It turns what would typically be a private boundary—the space between two towers—into a vibrant public corridor. This central transit hub becomes a civic anchor that reinforces the tower's identity as not just a building, but a piece of city-making infrastructure.

Given the complex challenge of balancing 24-hour public access with residential privacy in Urban Symbiosis Mix Use Towers, how did your design process evolve to create harmonious coexistence between these seemingly conflicting requirements?

One of the central challenges of designing Urban Symbiosis was orchestrating the delicate balance between constant public flow and residential seclusion. Our solution emerged through both spatial hierarchy and programmatic choreography. I established a clear gradient of accessibility—from the most public, like the transit plaza and commercial arcade, to semi-public co-working and amenity zones, and finally to fully private residential quarters.Circulation was a critical tool in this balancing act. I developed dedicated cores and access points for each major user group, while still allowing for controlled zones of overlap where interaction is meaningful and intentional. For example, residents can access amenity spaces such as the gym or co-working lounge without passing through the public retail corridor. Conversely, office workers and visitors experience the vibrant ground-level ecosystem without disrupting the privacy of residential life above.The architecture facilitates coexistence without friction—enabling different communities to share space while maintaining their own rhythms and boundaries. It’s a choreography of movement and access that allows the building to function as a shared organism without compromising individual comfort.

Production Technology
The design employed a mix of urban planning and architectural analysis. Advanced parametric tools were used to study the relationship between public access, energy efficiency, and user flow. Vertical stacking was replaced with a horizontal division of programs, creating integrated spaces. High-performance materials and all-electric systems were chosen to ensure sustainability, while shared amenities were carefully planned to enhance social interaction and community-building.
Design Challenge
The greatest challenge was achieving a balance between urban connectivity and energy efficiency. Ensuring 24-hour public access while maintaining the privacy of residential spaces required a complex design process. The horizontal split of programs presented structural and logistical difficulties, as did integrating shared public amenities without disrupting the functional core. Balancing public engagement with sustainability and energy performance was a key obstacle.
Research
Research focused on balancing mixed-use program demands in high-density areas. Data was collected on energy consumption patterns and spatial usage in residential and office towers. Parametric modeling tools informed the horizontal split design, optimizing building efficiency and interaction. The resulting insights revealed that the design could improve energy loads, reduce grid pressure, and enhance public-private space integration, contributing to a sustainable and socially engaged urban development.
Inspiration
The inspiration for the project stemmed from the symbiosis between residential and office programs, aiming to optimize energy usage by aligning their differing time demands. Drawing from urban connectivity principles, the project integrates public spaces with private development, influenced by the dynamic interaction between work and home life. Research on mixed-use high-rise buildings shaped its energy efficiency and public access approach.
Project Duration
