Patio Installation That Elevates Outdoor Living on Long Island
Stone, Structure, and Stories Made to Last
Patios and masonry are the backbone of outdoor living. From historic bungalows to modern estates, we design with intention and build with integrity. These aren’t just outdoor surfaces; they’re the gathering places, thresholds, and transitions that define how a home feels. Every paver, wall, and stone step carries our family’s legacy of precision, artistry, and purpose.
The Gary Duff Design Standard of Craft Excellence
Crafting patios and masonry isn’t just about stacking stone, it’s about balance:
-
Every line and angle responds to your home and your lifestyle.
-
Hardscape that feels native to the site and true to the house.
-
Stone chosen for strength, texture, and longevity.
-
Decades on Long Island teaching us how structures behave here, season after season.
-
Patios that connect indoor and outdoor, front yard to backyard, courtyard to poolscape.
We don’t just build stone, we create spaces where evenings feel right, conversations linger, and families come together.
Patios & Masonry That Define Outdoor Life
When we design and construct patios and masonry, we’re thinking about how you live: where you step, where you gather, where light hits, and where memories will unfold.

Guidance from Gary Duff Designs
Decades of experience have taught us a few things, here’s what most clients want to know before we start.
-
Fifty years of experience, and one family name behind every project. We approach patios and masonry as design elements, not add-ons. Each wall, walkway, and paver pattern is intentionally planned to enhance your property’s architecture, flow, and everyday use.
-
Yes. We’re a full design-build firm, which means the same team designs, manages, and builds your project from start to finish. This ensures consistency, accountability, and craftsmanship that reflects our family’s reputation for excellence.
-
We create everything from paver patios and stone walkways to retaining walls, seat walls, driveways, outdoor stairs, and stone veneer detailing. Whether it’s a small addition or a full-property hardscape, we bring the same level of care and creativity.
-
After decades designing across Long Island, we know how local climate, soil, and coastal weather affect materials. We recommend stone, pavers, and masonry finishes that stand up to the elements while complementing your home’s architecture and natural surroundings.
-
Every project is unique. The investment depends on size, materials, and design complexity. During your consultation, Gary Duff Designs will outline tailored options that align with your home, goals, and investment priorities, whether it’s a compact patio or a full-scale hardscape.
