A Proven Process for Custom Outdoor Living on Long Island
Design That Adapts to You
Every design begins with intention, but how it unfolds depends on your goals. A smaller project may follow a simple layout; a full-property transformation calls for layered design, multiple disciplines, and deeper collaboration. Our design-build process adapts to your needs, not the other way around.
Design Is a Conversation, Not a Template
Our process is refined yet personal, a balance of artistry and practicality that reflects our family’s 50-year legacy in custom outdoor environments. From your first meeting to the final plans, our goal is clarity, confidence, and design intention in every step.

-
Expect transparency from concept to completion.

Decades of experience in high-end landscape design and construction.

Where Our Craft Becomes Your Story
“Gary Duff Designs delivered a complete backyard renovation for us—pool, outdoor kitchen, pergola, outdoor shower, retaining walls, drainage and plantings—with outstanding results. Gary and Eric were on-site and in constant communication throughout, guiding us through the permit process and ensuring every detail was executed flawlessly.
