The firm was formed in 2009 by Luanne Urfer, principal landscape architect, to provide environmentally responsible commercial and residential design for our clients. SDG’s thorough understanding of the Alaskan environment provides the foundation for exceptional land planning and site design skills.

SDG is a Mat-Su Valley business supported by numerous professional consultants who supply expertise on an as-needed basis. SDG’s locations in Juneau and in the Matanuska-Susitna borough and owner residency provides us with unique perspective into the valley culture and values.

SDG provides services for both public and private clients throughout Alaska and the Pacific Northwest.
