About DDG

Duplantis Design Group (DDG) is a comprehensive design firm and is exceptionally experienced in managing all aspects of a development project.  In addition to our design services, we also provide clients with conceptual site planning and master planning, site investigation reports, assisting with property acquisitions, representation at public hearings, permitting, entitlements, and construction administration.

DDG has successfully completed over 2,500 projects across the Gulf Coast Region.  Our firm’s portfolio is vastly diverse in project types – industrial, commercial, retail, single family and multifamily subdivisions, education, municipal projects, master planning and feasibility studies, parks and recreation, coastal restoration and protection, and medical – just to name a few.  Additionally, we have experience assisting clients with many project delivery methods, including build to suit, reverse build to suit, design assist, design bid build, etc.

Whether through our in-house project management and design services or using a network of trusted partner firms, our team’s knowledge of material availability and construction practices have been invaluable in early planning decisions.  DDG has over two decades of experience managing every aspect of a project.  From the initial site assessment and due diligence through the project’s substantial completion, DDG’s team of design professionals pride themselves not only on the technical aspects of a project, but also on our ability to focus on exceeding a clients’ expectations and providing top rated client satisfaction.
