GGN is a landscape architecture firm founded in Seattle, Washington in 1999. Our firm’s 45 employees have backgrounds in landscape design, restoration ecology, architecture, engineering, and art.

GGN offers extensive experience in designing site-specific landscapes in complex, urban contexts. Derived from our research of each site’s history, ecology, and culture, GGN’s designs express the hidden stories and native ecology of each piece of land.

GGN’s work is highly varied in scale and type, from furniture to campuses. Prominent projects include the National Museum of African American History and Culture, the Lurie Garden at Millennium Park, the Bill & Melinda Gates Foundation Campus, and the Burke Museum of Natural History and Culture.

GGN received the 2017 ASLA National Landscape Architecture Firm Award and the founding partners received the 2011 Smithsonian Cooper Hewitt National Design Award for Landscape Architecture. The firm’s project awards include ASLA National Awards of Excellence, ASLA and AIA Honor Awards for Design, Tucker Design Awards, Society for Campus and University Planning Awards, and Great Places Awards from the Environmental Design Research Association.
