Info

RHAA is one of the founding firms in the modern landscape architectural movement. Our history began in 1945 when Robert Royston teamed with fellow landscape architects Garrett Eckbo and Ed Williams to form the landscape architecture firm Eckbo Royston & Williams. This partnership would grow and change over 34 years to finally evolve into Royston Hanamoto Alley & Abey in 1979. During these past five decades, we have had the pleasure of watching the beauty and character of our built projects evolve as generations of users are drawn to the inspirational spaces.
