[ GARDEN DORMITORY ] sustainabilit y through sunlight DESIGN 302 CRITIC SITE PA R T N E R
F A L L 2 016 BETH O’NEILL BROOKLYN, NY S H AU N M E H TA
Designed as a dormitory for the students of Pratt Institute, this project aims to answer two questions: how can we design a passively sustainable dorm, while also catering to the needs of the art and design students who attend Pratt? Access to daylight answers both of these questions best. Electric light usage is something that can be lessened, or even eliminated during the daytime by using passive design methods, and artists are always chasing the perfect light in which to create. The design approach is based on a solid/void relationship. The site is considered as a solid block then, with the use of computational software, is cut and shaped with light rays, creating two main voids that slice through to the backyard. These voids allow for more natural light to enter the center of the project and create optimal light conditions. The programmatic distribution revolves entirely around these sun cuts, with the communal areas surrounding the cuts and the living units rejecting them, which instead face the street. To control the insulation of the building aerogel panels are installed. The aerogel acts as a translucent insulated barrier, trapping hot air between the panes of glass. Vents can be opened or closed to heat the interior of the space.

After the removal of the two light voids, issues of structural integrity arose. The two voids converging into one created a massive cantilevered structure that required many rounds of trial and error to solve. The best solution that allows the structure to work, while also minimizing the amount of space the structural elements take up, included the use of a multi-floor truss system. The trusses use thick anchored columns at either end which the structure of the top few floors hang from. These trusses then became a sort of an ornament, that adds texture to the floor-to-ceiling glass walls.

[ FLUID BOATHOUSE ] elongating thresholds DESIGN 302 CRITIC SITE PA R T N E R

The design strives to soften the hard boundaries that have been created between the Columbia University athletic department and the surrounding neighborhood. The existing site has multiple areas of gradient space, in which ownership is not clearly defined. The only harsh boundaries that can be found are the fences, walls, and locked doors. The conceptual backing behind the design of this process was to eliminate any and all harsh boundaries or thresholds. Instead, the private spaces rely on elongating the thresholds in the form of winding hallways, hidden cuts in the walls, and walls that pinch. Depending on the level of privacy a given space requires, the more difficult and unknown the threshold was designed to be. This creates a psychological accepting or rejecting of the occupant in each space. *published in Pratt Institute InProcess 23

The form of the building is based on a study of metaballs, in which the two main structures are almost magnetically attached by the hallways in the middle. This design approach, as well as the main concept of creating smooth transitions, evolved into a rounded facade, where there is no difference between the walls and the roof. The facade is composed of custom-molded plastic composite panels. For light and air access, slits are cut along the width of the building. To create an elongated threshold between interior and exterior, the slits take inspiration from the James Turrel “Skyspaces”. The openings are not just punched out, but rather the facade is bent to create the illusion of disappearing into the sky.

[ FILLING THE VOID ] a center of social infrastructure DEGREE PROJECT 2 019 CRITICS MICHELE GORMAN & ADAM ELSTEIN SITE MA N H AT TA N , N E W YO R K
‘Filling the Void’ is a proposal for a network of social infrastructure that fosters the wellbeing of all the residents of Manhattan. The city will purchase all of the forgotten and vacant lots that are littered around the city, as well as the adjacent buildings. The existing buildings will become a co-op type housing, and the vacant lots are constructed into micro-centers of social infrastructure. These micro-centers include several programs, each that should be of intimate scale and provide some level of privacy. These centers are designed through a strategy that highlights the banal moments of pause within the residential programs, such as sitting, bathing, cooking, reading, etc. The elements related to these rituals that are innate to domestic practice are exaggerated and elongated. The elements reach out into the rift between the two buildings, creating a place that allows for the public to take part in the banal moments usually reserved for the private space that is the brownstone. The hard-line boundary between the exterior and interior, or, more explicitly, the public and the private, becomes malleable. The project fills the voids of Manhattan. Literally through the process of infilling the vacant lots, and figuratively through addressing the needs of more social infrastructures.

[ WAITING ] The city is tired. It is tired of being unfriendly, of being cold, of being unwelcoming. The city is ready to be compassionate, to fill in its gaps left from the forgotten spaces. The forgotten, the empty, the vacant lots. Empty and vacant but waiting. Waiting to be filled, filled with new opportunities to provide refuge. The city wants to provide refuge. The city wants nothing more than to help, to reach out, to contain, to protect, to conceal. The city is ready and waiting to give its vacant lots to be infilled. Infill turns to pockets. Pockets, that hold our most valuable items, our most intimate items. Infilled pockets that contain intimate space. Pockets that conceal from view, pockets that blend in, pockets that are hidden but seen. The adjacent enclosures sense a void, a rift, a gap. They sense the emptiness that is waiting, that needs a form to fill it, to conceal it, to protect it. The existing interiors push in and out, redefining the shape of the void between. Creating an alleyway, an alleyway that leads to a new world. An intimate place, a concealed place. These traces of existing spaces are shaped, reshaped, and shaped again by the bodies that occupy them. These pockets are made for, and made from, the occupation, curving to the physical and mental bodies that reside within.

[ PIMP MY FAHRRAD ] a center [of/for] bicycles DESIGN 403 CRITIC SITE
S U M M E R 2 018 DAGMAR RICHTER BERLIN, GERMANY
Sited at a very unique circular intersection in the neighborhood of Kreuzberg, most of the research for this project was completed while studying abroad in Berlin. This roundabout houses the U Kottbusser Tor, which is an entrance for both the above-ground and underground U-Bahn train stations that services the city of Berlin. An existing project proposal by the name of Radbahn is planned to pass through this intersection. The Radbahn is meant to serve as a ‘bicycle highway’ that runs below the elevated train station. Pimp My Fahrrad proposes an extension to this bicycle highway by creating a lightweight tensile structure to house a center for bicycles. The neighborhood of Kreuzberg is mainly a low-income neighborhood, with much of the culture surrounding the DIY movement that Berlin is famous for. This new center creates room for workspaces that allows the surrounding community to purchase donated bikes for cheap and attend workshops that teach how to repair, customize, and care for the bicycles. While attending the workshops, the community can have access to 3d printers, robots, and laser cutters that can teach them invaluable fabrication skills that they might not be able to learn elsewhere. The customization of the bikes is an extremely important part of the workshops, as it helps to show off each individual’s identity, while also creating a sense of ownership over the bicycles. In keeping with the idea of the ‘bicycle highway’, the center is surrounded by ramps that connect the bike path to the elevated and underground trains. These ramps are supported by lightweight cables that form multiple tent-like structures, which are then covered by ETFE plastics, creating an insulated, translucent covering for the workshops.

In an exercise of modeling, manipulation, and morphing, I first had to solve how to model the minimal surface ‘Neovious Genus 14’. Through the use of Rhino and Grasshopper, simple workflow for modeling complex surfaces is produced. Next, I developed a set of 3 tiles that composed to form a metaball. The development of “Tile B” and “Tile C” from the original “Tile A” was simple as the morphology of these 4-sided shapes are similar. The development of “Tile D” proved to be very challenging as it needed several evolutions to transform the 4-sided “Tile A” into a 5-sided shape. After all of the tiles were accurately modeled, they produced the Neovious Genus 14 Metaball.

The initial goal for this study was to find a way to fabricate a minimal surface using a wireframe construction. Issues in the prototype phase relating to inaccurate wire bending and difficulty of gluing/soldering at the joints lead to the development of a 3D printed jig that would accurately bend the wires as well as a 3D printed joint where the wires easily snapped into place. Once making the singular minimal surface was solved, exercises in an aggregation of the wireframe lead to the combination and discovery of new minimal surfaces. The joints were altered for the aggregated wires to be glued together at the points of contact to create a structurally sound frame for the fabric to be able to wrap and stretch without warping the shape.

The Autonomous House is a dual engaged program. It allows for occupants to both work and live in a single space. The Autonomous House is self sustained, employing polymeric panels on all sides that bio-manufacture algae to be dried into cakes and sold at a profit. The roof and southern facing panels are covered with a flexible photo-voltaic. This collected energy is converted to electric energy which power LEDS that create a contained greenhouse that has almost no need for natural light. The plants grown here will be used to produce food, fuel, and pharmaceuticals.
