What our clients are saying:

Residential Backyard Pool and Woodland Border Planting Design

The Woodland Border Garden


"Robert developed an amazing design that created spectacular seasonal color and enhanced the beauty of our woodland property . He was wonderful to work with and kept within our budget. We had spoken with several designers but no one matched his attention to detail or his knowledge of planting materials. After executing a spectacular design for our property he oversaw plant selection and installation. He was an absolute pleasure to work with and a true professional. Highly recommend him and can’t wait to work with him on next project!!"

Rooftop Garden


"Robert Khazzam designed our rooftop garden... He did an amazing job and my wife and i have been absolutely thrilled with the result. We came to Robert with only some preliminary ideas of what we wanted out of the garden. He developed a beautiful design that absolutely transformed the rooftop. He was very receptive to our thoughts and suggestions as the design progressed, but added a number of features that we hadn't thought of and integrated all of these features into a unified design with a polished, professional look. Robert had a very deep knowledge of the plants that were included in the garden. He included plants that worked very well for the climate and location, and as a result the plants have absolutely thrived. We've been fascinated to see the garden constantly change as the seasons evolve. He also had a thorough understanding of the requirements for installing the garden, so that the installation went very smoothly and the finished garden matched the design perfectly. I would highly recommend Robert for designing a garden or outdoor space, and we're very grateful for the work he did for us."
