CONCEPT:

Located on the site of Bushwick Inlet Park in Greenpoint, New York, this project brings together a greenhouse, marketplace, education center, restaurant spaces, and a composting facility—each functioning as its own system—within a landscape that negotiates the boundary between urban infrastructure and natural ecology. A series of new enclosures are inserted

THE DATASPHERE

PRATT INSTITUTE: DESIGN5:ADVANCEDDESIGNRESEARCH

Professor: Lindy Roy, Daniel Garcia

LOCATION: WAXAHATCHIE, TEXAS

SOFTWARE: REVIT, RHINO, ADOBE ILLUSTRATOR, GRASSHOPPER, PHOTOSHOP, RUNWAY, V-RAY, JAVASCRIPT

The Datasphere is a network of bio-engineered storage facilities situated within the abandoned shafts of the Superconducting Super Collider (SSC) in Waxahachie, Texas. The project secures sensitive, dormant data by encoding it into plant DNA and housing it within a labyrinth of structural mycelium bricks.

Data Density Study. A visual comparison of traditional hardware versus bio-encoded matter. To meet the demands of the coming ‘Zettabyte Era’ (59 ZB active data), the project utilizes plant DNA to condense warehouse-scale storage into microscopic biological volumes.

Site Analysis: The Subterranean Incubator.

A vertical survey of the SSC shafts reveals a unique atmospheric gradient. While the surface is variable, the deep tunnels (250 ft) maintain 92% humidity and stable temperatures around 68°F. These conditions transform the abandoned infrastructure into a perfect natural growth chamber, fostering rapid mycelial expansion without the need for artificial climate control

Synthetic Biology Workflow. Bridging the gap between the digital and physical worlds. This diagram outlines the six-stage procedure required to migrate active data from electronic circuits into the cellular structure of bio-engineered mycelium, locking information away in a self-repairing, dormant biological format.

Section: The Excavated Growth Zone. Visualizing the infrastructure required to turn code into matter. This chamber provides the necessary environmental controls for data fabrication, featuring integrated steam supply for humidity regulation and a closed-loop decontamination system to manage biological output

Interior Perspective: The Data Vault. Inside the ‘Cooling Labyrinth,’ architecture functions as a machine. The jagged arrangement of the storage creates a high-performance thermal mass, absorbing heat while channeling cool air drawn from the open vertical shafts. This passive system protects the integrity of the DNA-encoded matter without the energy costs of traditional server cooling

THE SPONGE INITIATIVE

PRATT INSTITUTE: ARCHIPELOGICS

PROFESSOR:DAVIDERDMAN

LOCATION: BADUK, SINGAPORE

SOFTWARE: REVIT, ENSCAPE, RUNWAY, V-RAY, PREMIER PRO, RHINO, GRASSHOPPER

The Sponge Initiative is a scalable infrastructure project designed to bolster Singapore’s water security by rendering the urban fabric more permeable. Through a transect analysis of the island, the project identifies the Bedok HDB estates as a prime site for hydrological intervention. The strategy retrofits existing housing for on-site water processing and urban farming, while transforming adjacent parks into active retention reservoirs to absorb, filter, and reuse runoff.

Façade Detail: The Living Machine. A close-up of the retrofit’s active skin. The design layers a secondary infrastructure over the existing HDB face, featuring transparent vertical conduits for rainwater transport and filtration. Integrated into the framework are modular hydroponic planters and micro-turbines, allowing the building envelope to simultaneously generate food and energy while managing water runoff.

STACKED COMMONS

PRATT INSTITUTE: ARCH770:CONSTRUCTINGCOMPLEXITIES

PROFESSOR: CRISTOBAL CORREA

LOCATION: BROOKLYN, NEW YORK

SOFTWARE: REVIT, ENSCAPE, V-RAY, RHINO, GRASSHOPPER

This project extends Pratt Institute’s Higgins Hall into the back courtyard by pulling out “drawers” from the building’s central mass to create new floor plates and flexible program space on every level.

Two vertical rods pierce the addition, acting as both structural anchors for a cantilevered diagrid curtain-wall façade and as light shafts that bring daylight deep into the interior. The ground floor merges an expanded gallery with a café/lounge and commons that open directly to the courtyard, while the second and third floors operate as studio extensions that double as lounge, pin-up, and presentation zones during heavier academic periods.

The top floor sits directly beneath the cantilever and becomes an active social hangout with access to the rooftop of central Higgins, offering students a place to decompress, smoke, or step outside. Overall, the design strengthens Higgins Hall with more studio capacity, a stronger public interface, and student-centered social spaces, transforming the courtyard into a vibrant extension of campus life.

Façade Assembly: The Diagrid Module. A breakdown of the building envelope’s primary unit. The design utilizes a custom Steel Frame to hold a tessellated pattern of inserts, alternating between Clear Window Units for views and Opaque Window Units for solar control. Integrated Operable Window Units allow for natural cross-ventilation within the studio spaces.

MODULAR INTERVALS

PRATT INSTITUTE: DESIGN3:BUSHWICKHOUSES

PROFESSOR: STEPHANIE BAYARD

LOCATION: BUSHWICK, NEW YORK

SOFTWARE: REVIT, V-RAY, RHINO,

Situated within the NYCHA Bushwick Houses, this proposal introduces a new residential tower composed of three distinct apartment typologies. The units are stacked and interlocked, utilizing a push-pull strategy to generate a dynamic façade of private terraces and passive sun shading. The interior is activated by vertical light wells and shared office amenities, while the ground plane opens into a monumental 25-foot tall courtyard dedicated to local artists and merchants.

Residential Configurations. Plan studies of the three unit variations. The typologies range from 2-bedroom simplexes to flexible duplex arrangements, all organized within a standard 25’-0” width to ensure structural continuity while maximizing spatial variety.
