Servicing Hawaii with 35+ years of experience..


"Design is a universal language. Dignified or dynamic, classic or contemporary, sophisticated or simple, it inspires the places we live, work and play. It calls forth our personal experience and connection to one another, wherever we are in the world."

- Maurice Yamasato


YH Architects started out as Maurice H. Yamasato AIA and Associates over 45 years ago. In the early years, the firm specialized in custom residential projects and later expanded its portfolio to include planning, commercial, retail, chain restaurants, government and a larger and more diverse scope, including civic centers, warehouses, and military facilities.
