Extend Your Outdoor Living—Season After Season
Custom-designed 3-season rooms and glass enclosures that bring protection and beauty to your outdoor space year-round.
Outdoor Living, Without Seasonal Limits
You’ve invested in your outdoor space, but for much of the year, it sits unused.
Too hot in the summer. Too cold in the winter. Too exposed when the weather turns.
Most outdoor structures look great, but they don’t adapt with the seasons. And when you try to enclose a space after the fact, it often feels like an afterthought, disconnected from your home and uncomfortable to use.
Where Outdoor Comfort Meets Year-Round Functionality
At Gary Duff Designs, we create custom 3-season rooms and glass patio enclosures on Long Island that are designed from the start to extend how and when you use your space.
Whether integrated into a pergola, patio, or covered structure, our enclosures are built with intention—so your outdoor environment feels just as comfortable and functional as your interior.
The result: a space you can enjoy far beyond the limits of traditional outdoor living.
Designed for Year-Round Living
A properly designed enclosure transforms how you use your home. Gary Duff Designs creates custom outdoor enclosures that help you and your family enjoy the space all year long.
Stay comfortable during cooler months without sacrificing natural light
Reduce wind, rain, and seasonal limitations
Maintain open views while adding structure and usability
Create a flexible environment for relaxing, dining, and entertaining
This is outdoor living without the limitations.
Intentionally Integrated, Never Added On
Gary Duff Designs doesn't retrofit enclosures. Our experienced team designs them as part of a cohesive outdoor plan.
Every glass enclosure is integrated with surrounding elements like patios, outdoor kitchens, fire features, and lighting, ensuring the space feels intentional, not added on.
We consider:
How the enclosure connects to your home’s architecture
Sightlines, light flow, and seasonal sun exposure
Ventilation and comfort throughout the year
How the space will actually be used day to day
Our design goal is to make your outdoor space a true extension of your home.
High-Value Features That Maximize Comfort
Integrated Heaters
Take your enclosure from seasonal to nearly year-round with built-in heating solutions. Discreetly installed and placed with purpose, heaters allow you to enjoy your space comfortably even as temperatures drop.
