After 40 years, we call ourselves masters in designing beautiful, classic, and functional outdoor living spaces. From pools, patios, plantings, front entrances - and everything in between, we put our love and knowledge in every detail. It all starts with getting to know your style, your home's architecture, and your expected use. We then design a landscape that we know you'll love for decades to come.

Where Our Craft Becomes Your Story

I have worked with Gary extensively during a renovation project on my home. He is the best contractor I have ever worked with...his attention to detail, creativity, responsiveness and overall caring attitude truly set him apart. This was my first experience with Gary Duff Designs and I am a Gary Duff customer for life. I would highly recommend Gary Duff Designs to anyone.

Protection & Privacy

These luxurious shade features are designed for year-round protection from harmful UV rays, annoying insects, and winds—without jams, snags, or hang-ups. Now you can quickly enclose your outdoor living spaces to provide comfort and privacy and linger a little longer in the great outdoors.

Where Our Craft Becomes Your Story

“We chose this company to design our entire backyard. Pool, patio, kitchen and other things. They far surpassed our expectations. They have a great work crew with wonderful attention to every last detail. We couldn’t have been happier throughout the entire process.”
