TCA Architects

18821 Bardeen Avenue, Irvine, CA 92612

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. Then clients can experience the resulting architecture through sketches, 3-D models, and photorealistic renderings. 

Aram Chahbazian, AIA, is the President and CEO of TCA. He draws from over 32 years of experience in multi-family design and mixed-use properties. Under his leadership, TCA Architects has completed landmark mixed-use and high-density housing projects, such as G-12 and Olive in downtown Los Angeles (LA) and the Camden in Hollywood. A Leadership in Energy and Environmental Design (LEED) Accredited Professional, his work has been recognized by the AIA, the National Association of Home Builders (NAHB), and the Pacific Coast Builders Conference (PCBC). 

La Placita Cinco, an inclusive community that reinvigorates a 50-year-old retail center, is one of TCA Architects’ finest pieces of work. The project consists of family-oriented affordable homes, outdoor amenities, and a repurposed commercial center. The former gas station and a portion of the parking lot were replaced with a mixed-use building with bedroom apartment homes and ground-floor community space.
