Bringing art, engineering, and innovation to outdoor spaces

Blue Homes


Firma Design Group creates beautiful, functional, sustainable outdoor spaces for homeowners, developers, institutions, and municipalities in California, Nevada, North Dakota, and beyond. As a multidisciplinary firm of landscape architects, planners, and civil engineers, creative collaboration is in our DNA. Our clients are an essential part of the process, from conceptual ideas to scheduling and budgeting, and our innovative designs represent the thoughtful integration of a client’s goals with the opportunities and constraints specific to each site.

With our attention to detail, service oriented approach, and a thorough understanding of planning requirements, Firma Design Group has earned a reputation for excellence. Our principals have over five decades of combined experience, and have developed great working relationships with local municipalities. This enables our clients to get the permits and approvals they need without frustrating delays.

We are fluent in the development of sustainable and “green” project designs, working drawings, technical specifications, and construction observation. Our in-depth experience spans a wide range of projects, including streetscapes, downtown redevelopment, urban and rural parks, mixed-use commercial/residential spaces, high-density and single-family residential developments, custom homes, and habitat restoration.
