Water Feature Installation That Adds Calm to Long Island Landscapes

Built for Stillness and Crafted for Sound.

Water softens a space, quiets the mind, and draws you in. At Gary Duff Designs, we don’t install water features, we compose them. Each pond, waterfall, and fountain is living architecture, balancing movement and reflection, structure and calm. Every detail is intentional, every sound designed to belong.

Where Art Meets Balance

Creating the perfect water feature is about understanding flow, sound, and placement.

  • Each design enhances its surroundings, never competes with them.

  • Each system is engineered for sustainability, clarity, and harmony.

  • Built for Long Island’s terrain, climate, and soil conditions.

  • Precision-built water elements that perform beautifully for years.

  • Every project carries our family’s signature attention to detail.

Design That Flows Naturally


We treat water as both material and muse. At Gary Duff Designs, every element: flow, sound, reflection, is shaped with intention. Each feature is composed to fit the land, the architecture, and the way you live outdoors. The result is design that moves naturally, built to calm and captivate. Because the best designs don’t compete with nature, they work with it.

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.


  • That depends on your goals, layout, and sound preference. Some homeowners want the stillness of a pond, others prefer the motion and sound of a waterfall or sheer descent. We’ll help you design one that feels natural to your home and landscape.

  • Not when designed correctly. Our systems are engineered for balance and efficiency—using proper filtration, circulation, and materials that minimize upkeep while maximizing clarity and performance.

  • Absolutely. We frequently integrate fountains, pool water walls, and sheer descents into existing outdoor spaces. Every design is customized to blend seamlessly with what’s already there.

  • After fifty years working on Long Island, NY, we know how to build for the freeze-thaw cycles and coastal air that define the region. Every water feature we create is built to last—both structurally and visually.

  • Every project is unique. The investment depends on the scale, materials, and design details. During your consultation, Gary Duff Designs will outline the best approach for your property—whether you’re envisioning a simple fire ring or a full custom stone fireplace.
