Wilson Davis Associates

California
Architect
Commercial, Healthcare, Industrial and Energy, Institutional, Residential
Design and Engineering, Landscaping
Wilson Davis Associates (Wda!) was founded in 2019 and is a Landscape Architectural Design Firm preparing Conceptual Landscape drawings for project entitlements, Construction Documents for bidding and construction and Construction Administration during construction. Wda! has two licensed Landscape Architects and two staff members that help with production drawings and an Office Manager. Wda! has designed projects in Northern California / Bay Area to San Diego County and east to Las Vegas and Phoenix areas. The projects include both the Public and Private sectors involving Parks, Plazas, Streetscapes, Commercial Retail, Office, Single Family detached housing, High Density Housing / Apartments, Industrial and Institutional. Wilson Davis Associates (Wda!) prides itself on the ability to consistently provide quality landscape design. What is of equal importance to us is the capacity to give our clients a creative product; "on time and within budget." In landscape design a "team" approach means more creative energy for the benefit of the client. This is the direction we take for all of our projects at Wda! Each client is encouraged to develop a personal working relationship with our principal and associates as well as our project managers and production staff. The value of this personal attention has been proven again and again over the past years, providing faster recognition and resolution of problems and giving unparalleled sensitivity to our clients' particular needs. We feel that this is a major reason why we have such a long list of successful projects and satisfied clients. The Wda! approach unites concerned and talented professionals who work together to ensure quality at every stage of the project, from research and analysis to design development, from construction documents to field observation. Every consideration is given to all of those who may be involved with the project: investors, municipalities, other consultants, and the ultimate user. The result is a product that meets each of our client's unique requirements in terms of budget, schedule and marketability...and, of course, meets our goal of providing quality landscape design services.
