A Passage Through Time Portman Studio Spring 2020 Instructor: Charles Rudolph
Keywords: Adaptive reuse, Carbon Emission, Material Accountability, Circular Economy Through the initial analysis and subsequent reconfiguration of an existing urban building, the idea was to experiment with the properties and capacities of both renewable and reused material and their application to new hybridized forms of building assembly and urban social space. The Proposal transforms the existing building into a library for the community by inserting a wooden box which houses the circulation, book-stacks and Garden. Maintaining the existing structural system the new insertion brings in light and acts as a transition between the formal and informal zones in the building. The formal side of the building keeps the entire building facade intact serving as a memory of the old whereas the informal side of the building resembles the ruin that remains by performing stereotomic traits on the brick facade. 1
Existing H. L. Green Building, Atlanta The setting for this ambitious exploration is south downtown Atlanta, at the intersection of Peachtree St. and Martin Luther King Boulevard. The H.L Green Building, a deco-modern masonry-clad structure built in 1933, anchors the northern end of a block of low-rise commercial structures. The 1980’s era Fulton County Government Center complex is across the street to the east, and the white marble Modern-style Martin Luther King Federal Building (built by the US Postal Service) is two blocks to the west, backing up to the railroad tracks at the gulch. A once-thriving social space, it was cut off from “upper” downtown and the Fairlie Poplar district alongside the Peachtree St. corridor by construction of Five Points station. Broad Street’s shopping corridor forms an axis with the Five Points and Garnett MARTA stations at either end.

URBAN REPOSE Advanced Studio 1 Fall 2019
Instructor: Michael Gamble
Keywords: Descriptive Geometry, Experiential Phenomena, Masonry/Stereotomy, Sacred and Profane Space. As U.S. cities are once again resettled, many new developments are focused on profit driven commercial models which preclude speculative thinking around simple existential needs like repose and remembrance. The project seeks to counterbalance this trend and move away f rom generic consumer urbanity, towards the design of a place that promotes contemplation, excites the senses, and provides a strong threshold between what Mircea Eliade defines as the sacred and profane - a simple yet profound dialectic that can fuel the architectural and experiential imagination. The challenge is to create a house of meditation/interment and a garden, which embodies the highest aspirations of architecture by elevating the elemental, acknowledging the visceral, and promoting the poetic. 15
SITE DESCRIPTION AND PROGRAM The site is located in the northeast corner of the Bellwood quarry which has served Georgia city for more than 100 years as a granite quarry. The granite carved f rom Bellwood was used all over Georgia as pavements, flooring and curbs. After 100 years of excavating the site, the current site resembles a dilapidated ruin with rough edges and steep slope. The site is proposed to become a part of Atlanta’s Beltline project and in future will serve as the city’s largest public park. The project of a columbarium carries a lot of emotional weight and the design responds by creating a monumental volume for the columbarium and meditation areas oriented according to the sun position. The program consists of two primary meditation areas, one tertiary and secondary mediation area placed adjacent to the columbarium for 10,000 urns. The meditation areas are active according to the time of the day. The vertical circulation is through a staircase spanning throughout the columbarium along with service areas and lifts for better accessibility.

“Before transforming a support into a column, a roof into a tympanum, before placing stone on stone, man placed the stone on the ground to recognize a site in the midst of an unknown universe: in order to take account of it and modify it.� - Kenneth Frampton

KERN FORM The contrast of a perfect cuboidal form in the middle of craggy landscape of the site amplifies the monumental scale. The enormous void created inside the perfect cuboid using a series of tapering cylindrical form stacked on top of each other with an oculus light source. Meditation rooms cut through the external cuboid to allow natural light into the columbarium. 23
KUNST FORM The columbarium space, because of its overwhelming scale, reminds people of their fleeting existence and the staircase allows people to reach the cell of their loved one to pay their respects by placing mementos like photographs, flowers or other such memorabilia which can serve as a memory of the departed. 24
“The concept of the enactment and reenactment of man through history is not only metaphorical and mythical but also corporeal, in that body reconstitutes the world through its tactile appropriation of reality� - Kenneth Frampton 25

M. L. K. Sr. School, Atlanta One of the country’s first structures to be named after Dr. Martin Luther King is surrounded by old-growth trees, a lush park, and a budding neighborhood. To let the light in, the architects made a concrete surgery —a complex job, given the steel beams that laced throughout the building and the inability to move walls and added vertical windows that complement the original Brutalist style, offer a fresh look, and, most important, provide muchneeded daylight. The existing structure, built in 1973, has been given new life with increased natural daylight, a glass multi-story entrance, and splashes of color throughout.

THE WINGS OF PEACE Media and Modeling II - Fall 2019 Instructor: James Park This study aimed to analyze the selected architectural project, in our case the WTC Transportation Hub, in terms of its mass, volume and building systems. This analysis was then utilized to derive a possible parametric logic for this precedent form via a Grasshopper script. The finality of this exercise was the optimization of the derived logic via Galapagos, to achieve a building shape and size that would provide the best output with a fixed set of input parameters. 53
WTC Transportation Hub Santiago Calatrava New York, U.S.A 2016 The hub is in the World Trade Centre complex and within the Financial District neighborhood of Manhattan, New York City. With a 168-foot-high A-f rame and a white winged organic form, Calatrava originally conceived the Oculus to represent a “bird being released from a child’s hand as a gift of life and hope. He hoped the building to be “a witness of belief that we can overcome the tragedy”, a symbol of camaraderie of the American people and a gift to the community. The white curved supports that extend outward like wings and the skylight, run the length of the concourse that is approximately 111 meters long and 43 meters wide. These supports are arranged formally along the length of the larger curve of the geometry and structurally interlock high above the ground. The space between these is glazed to allow maximum daylight within the building.

CONSONANCE OF COLORS Location: Goa, India Academic work Recognition: 1st rank in Mumbai University Instead of usual box structures, the design intends to be a very open-ended building, spreading its wings out, aiming for growth. The greatest possession of a circle is that it has no definite boundary. And that’s the main reason why the design doesn’t have linear structures because the fashion design space shouldn’t have any definite visual boundary. The amphitheater in the center of the structure creates a sense of unity as well as keeps all the spaces bounded and acts like an open courtyard, for better socialization among students. 73
