Pools & Poolscapes

Inground Pool Installation Designed for Long Island Outdoor Living

Design That Flows With the Land

A pool should feel like it belongs, part of the landscape, not apart from it. At Gary Duff Designs, we create custom swimming pools and poolscapes that merge architecture, environment, and lifestyle. For fifty years, our family has designed and built pools and spas across Long Island, NY, each one crafted for balance, beauty, and longevity.

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.

  • We design and construct custom swimming pools, fiberglass pools, and pools with spas that complement your property’s layout and lifestyle.

  • Every pool is part of a greater poolscape design. We consider architecture, elevation, and sightlines to create a pool that feels connected, not placed.

  • Yes. Our team designs and builds pool patios, pool decks, and pool landscaping to create one cohesive outdoor environment.

  • We prioritize low-maintenance materials and systems designed for Long Island’s climate. Each pool is built for longevity and ease of care.

  • Every pool is custom, and investment varies based on size, materials, and complexity. During your consultation, Gary Duff Designs provides clear guidance on scope and options to help you make the right decision for your home.
