Charles Anderson Landscape Architecture (CALA) and The Green Room (TGR) are a regional, national, and international, Phoenix-based landscape architecture practice. The design firms founded by Charles Anderson, FASLA, and Charlie Ray, ASLA are focused on the goal of creating places for civic expression which reveal ecological and social phenomena, processes, and relationships.  This strategic partnership brings together vanguard design with youthful energy and with decades of field tested practice. CALA I TGR has an extensive record of award-winning multi-disciplinary park, plaza, open space and residential projects. Many of our projects involve public participation, including collaborations with community and neighborhood groups and public presentations. Examples of our civic-scale projects include the Metropolitan Park in Athens Greece, International Peace Garden Project Canada/USA and the Olympic Sculpture Park for the Seattle Art Museum. Our residential work is unsurpassed in both quality and breadth of scale. This work includes the smallest of gardens to extensive estate projects. Whether small or large, our work is always tailored to the client, collaborating designers and especially for those who will use it.


Our commitment to art, ecology, and the exploration of landscape form is complemented by an extensive background in all levels of the design and construction process, from site analysis and master planning to design development, construction documents, bidding and on-site construction review. We provide creative, efficient, and highly personalized professional services in the art and practice of landscape architecture and landscape design.



Charles Anderson, FASLA,  Principal

Practicing landscape architect for over 25 years, Charles Anderson has crafted numerous award-winning projects recognized for their ability to integrate art, nature and cultural elements. With degrees in Landscape Architecture from Washington State University and Harvard and has a penchant for teaching, he continues his query of art and science on his chosen profession. His work is grounded in horticulture and ecology which forms the basis for an evolving body of work that highlights the transformative processes of ecological systems, creating socially-relevant spaces and galvanizing the energy of others to advocate for landscape and open space.


There are two distinct threads that are part of every project and which also define the trajectory of the larger body of work. The first is a genuine love of nature, rooted from growing up out-of-doors, on the rolling plains of North Dakota. The second is a passion for the arts, particularly land art, and sculpture. Pivotal are the works of Robert Smithson and James Turrell who share a fascination with the study of light, landscape as art, and metamorphosis. The love of wild landscapes and contemporary art inform the work philosophically and provide a lens through which the projects can be understood. Using a palette of predominantly native plants and materials, Charles brings wild, dynamic landscapes into the city—elevating the “wild garden” to urban art.

Charlie Ray, ASLA, Principal


With the formation of The Green Room in 2005, Charlie has had the opportunity to design exceptional landscapes which represents his passion for nature, art, and the connection to  people and places. Charlie’s innate understating and design sensibility was cultivated by his parents at a formative age while growing up in the inspiring Sonoran Desert. His collective education, in the School of Architecture and Fine Art at UC Berkeley, California College of the Arts, and Arizona State University, introduced him to a number of extraordinary design mentors that played a significant role throughout his education and career.


Mr. Ray has been recognized for designing a distinguished and notable body of commercial and private estate work throughout the country. Within this diversity, a common design tread exists which celebrates nature, people, and places, while creating an environment which elevates one’s experience and heightens the senses. Mr. Ray’s design acumen and extensive knowledge of natural and architectural materials allows him to design outdoor spaces that transcend environments and creates a timeless appeal.  Charlie’s passion for creating stunning and compelling landscapes has become a natural extension of himself, while celebrating people and nature together in the most meaningful way.
