Inspired by cultural narrative and evolutionary design, TCA Architects is dedicated to creating experiences that champion community and promote forward-thinking change. From a complete evaluation of the opportunities and constraints of each site, TCA explores various ideas through design illustrations in order to generate a “Big Idea.” The overall fabric of a project and its spatial relationship—including façades and a range of construction materials– are then identified. Afterward, clients can experience the resulting architecture through sketches, 3D models, and photorealistic renderings.

Eric Olsen, AIA, LEED, AP is a partner at TCA and the Principal-in-Charge of the firm’s Los Angeles office. With more than 24 years of experience in master planning, mixed-use, TOD, and high-density and affordable housing, Eric leads TCA LA’s project teams and provides overall office management.
