Gary Duff Designs

About us

Since 1976, Gary Duff Designs has been designing and building custom elegant landscapes in Nassau and Suffolk counties. Our most important values continue to be providing personal service and high quality landscape design and construction. We believe that the smallest details make the biggest difference - from our communication all the way to every plant and stone we touch. From pools, patios, plantings, front entrances - and everything in between, we put our love and knowledge in every detail.
