GRADUATE ACADEMIC WORKS

ABOVE AND BEYOND BioTech Incubator using BioShellcrete Concrete Plant Park, Bronx, New York Biodesigned Objects by Professor Frank Melendez

The incubator accommodates various users, while facilitating reseatrch and development on fabrication and architectural application of BioShellcrete, a biocomposite made from upcycling discarded eggshells. BioShellcrete constructs a circular economy model for eggshells from a common household waste to an architectural material that can be remodeled and later used as park soil fertilizer.

FROM GROWING TO CRAFTING Bamboo as the makerspace essence South Bronx, New York Makerspace as the New Factory by Professor Gustav Fagerstrom

ENVIRONMENTALLY RESPONSIVE By choosing a site in a polluted area viz. South Bronx and building a green landmark in the form of a makerspace, we create a positive impact on the community. RETROFITTING Showcasing the potential of existing buildings to be transformed into energy efficient facilities by retrofitting the envelope. MAKING The idea is building and designing with bamboo on different scales due to its material qualities and rapid growth rate. ARCHITECTURAL DESIGN/ CONCEPT The programmatic juxtaposition of technology with collaborative and educative social spaces spanning the activities from growth to the final product in a single facility. PROTOTYPE The holistic approach of the making process enables the space to be an "architecture that builds itself".

STEP BY STEP: AN INCREMENTAL APPROACH Designing Suburban Future Rochdale Village, Queens, New York City Housing 55PLUS by June Williamson

The project takes on the task of creating a stimulating dynamic environment for an array of people ranging from those embracing and experiencing old age to those transitiong into this third phase of life. The proposal explores design for healthy and supportive aging in community within a “NORC,” or NaturallyOccurring Retirement Community" in a modular format allowing for expansion and alteration to promote natural integration in the larger surrounding fabric.

UNDERGRADUATEÂ THESIS

REVIVAL: UPLIFTMENT BY INHERITANCE Triggering growth by capitalizing on collective inheritance Mandvi, Gujarat, India Guided by Professor Pragnesh Shah

The facility is designed to preserve and uplift the traditional wooden ship (dhow) building industry as a means of reviving the stagnant economic growth of the city; additionally creating heritage tourism as a supporting fiscal backbone. The strategic multifunctionality of campus allows education, culture, heritage and tourism to harmoniusly cohabitat a scenic area of the city
