OUR HISTORY
A Legacy of Design Excellence
TRE Architecture boasts a rich legacy spanning over 58 years, beginning in 1967 when Amato Teta founded his architectural practice in San Diego after graduating from Carnegie Mellon University. His dedication to thoughtful, high-quality design earned the firm a strong reputation and a loyal base of repeat clients.
Continuing the family tradition, Allan Teta earned his architecture degree from the University of Southern California and gained valuable experience with several award-winning firms. In 2006, he joined forces with his father to form Teta Architecture, Inc., marking a new chapter of innovation and collaboration.
Building on eight years of successful practice together, the duo established TRE Architecture in early 2014—combining decades of experience with a forward-thinking vision to make a lasting impact on the field of architecture.

The meaning of TRE
TRE—named after the Italian word for three—is a tribute to the founder’s heritage and a timeless architectural foundation. The ancient Roman architect Vitruvius identified three essential principles for a well-designed building: utilitas (utility), firmitas (strength), and venustas (beauty). Drawing on this wisdom, TRE Architecture reimagines these classical ideals for a new chapter in architecture, embracing them as its core values: Enduring, Enriching, and Remarkable.
