Ray Tse is an architect guided a by clear understanding of the impact of his designs. Responsibility, to context, to communities and the client, directs his choices as a designer and his decisions as a leader. As principal at KTGY, Ray is involved through all design phases and specializes in developing strong concepts that excite clients. Ray’s goal is for each client to walk away with contextual, balanced design solutions that exceed expectations, invigorate communities and elevate the built environment.
Working in high rise and multifamily design for over 20 years, Ray’s first fascination with architecture came from looking up. Born in Hong Kong, as a child he was transfixed by the city’s monumental skyscrapers. When his family moved to New Orleans, he was equally taken with how that city’s unique cultural confluence is reflected in the built environment. Over his career, Ray has worked in different typologies but maintains an affinity for striking, soaring structures. He served on the AIA Board of Directors in Baton Rouge and he remains an active participant in AIA committees and in the ACE mentorship program.
