MODULAR SYSTEMATIZATIONOBJECTIVE:To generate a stystem of aggregated units for a performance space.

DESCRIPTION:The selected site for the performance space was the Schindler house. The project’s focus on experimenting with materiality lead to the investigation of using a polygon unit, a trapezoid, to create various patterns and forms. The trapezoid module was combined to form two other modules, the hexagon and the dodecahedron. All three modules were utilized to structure the performance space and create a user experience similar to that of the Schindler house. By creating pixelized transparencies and growing vegetation on the structure, the outdoor performance space takes advantage of the pleasant Southern California climate.

E PANDING CITY


OBJECTIVE:Thesis project proposing an urban solution for the future

DESCRIPTION:As our urban population continues to grow, cities become over-densified. Cities have expanded outwards causing urban sprawl. The sprawling movement has created suburbs on the outskirts of the city. The low density suburbs encourages automobile dependency due to the longer distances that must be traveled. Therefore, sprawling cities have known to become heavily reliant on the automobile and as a result, problems such as more traffic fatalities, traffic congestions, long commutes, and air pollution occur.To resolve these problems, we must reverse the sprawling process by revitalizing the urban core. By expanding the city upwards, space around the city core can be maximized for use. The skyscraper of today has tem-porarily provided the space necessary to accommodate our population. However, typical skyscrapers are dead end structures that become dis-connected from the city as they rise higher above the street level. Rather than extending single buildings upwards, why not extend the entire street upwards? A 3D street offers the space needed in high density urban zones along with the continuous flow that a street provides.


HIGHLAND PARK MEDIUM RISE HOUSINGOBJECTIVE:To develop a housing type responsive to urban issues drived from site contours, building orientation and a desire for natural light, ventialtion and physical access.

DESCRIPTION:Highland park is one of the most scenic neighborhoods in Los Angeles offering views to parks, hills, and valleys and views above the LA cityscape. A formal investigation of stepping units was made to provide units with optimal views, sunlight and natural ventilation. The complex wraps itself around 3 main courtyards serving users with a variety of ammenities such as a pool area, a gym, and private gardens.

KOREATOWN MIXED-USE HOUSING DEVELOPMENT

Corner Detail Model

OBJECTIVE:To create a development project with an understanding of how to form a complete proposal using financial data and architectural design solutions. The course was driven from the point of view of the developer. Not a developer that solely seeks profits, but one that consid-ers the opportunity to design something to give back to the community.

DESCRIPTION:Located just behind Western Ave. and Wilshire blvd., the site is ideally located in close proximity to major commercial and retail areas in Koreatown. The L-shape building opens up to a large pedestrian friendly courtyard with retail on the ground floor facing the inter-secting streets. The use of outdoor space is optimized by providing users with a variety of outdoor spaces. A private pool area and courtyards are hidden behind the structure while every unit has its own outdoor space.
