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.


  • Simply complete the contact form or call us directly at 631-445-0635. We’ll discuss your goals, property, and timeline, then schedule a convenient time to meet and start shaping your project vision.

  • The first conversation is about understanding, not selling. We’ll walk your property, listen to your ideas, and share honest guidance on what’s possible for your space, scope, and investment.

  • Yes. We take on select projects starting at $10K, and our team brings the same level of care and craftsmanship to smaller enhancements as we do to full-property outdoor living designs.

  • That depends on the project scope and season. Once your design plan is approved, we’ll provide a clear schedule and handle every detail, from permitting through construction, to keep things moving smoothly.

  • Yes, our office is located at 487 Furrows Road, Holbrook, NY. Visits are by appointment so we can give you our full attention. We’re happy to meet in person to review plans, materials, or discuss your ideas one-on-one.
