Skyscraper

Los Angeles is undergoing several transformations: the revitalization of the city’s fragmented downtowns, the dichotomy of new skyscraper buildings and traditional vernacular, and incorporation of Asian themes, owing to the city’s proximity and economic relationship with the East. The site, facing Pershing Square, lies between historic buildings and new high-rise skyscrapers. The downtown area surrounding the site is at a junction between the old and the new where many buildings in the downtown area have been redeveloped.

Work was divided between the individual site design and a group study of Los Angeles. The study of Los Angeles focused on the city’s history, public transit, location as a global hub, and building vernacular. This culminated in a large hand inked sheet and a wood model of downtown Los Angeles.

My design for the site is a mixed-use skyscraper with commercial activities in the plinth and residences in the tower above. The design challenge was dealing with two completely separate circulation cores that never interact but individually, can cater to the diversified needs of both residential and commercial activities. In the context of Los Angeles, the shape of the building’s tower, a star octagram, combines a promise for the future. The units themselves are identical, but rotated with large cantilevering balconies help define the structure’s shape.
