From your home to the shopping mall, landscaping is an important part of an property's visual impression. Our mission to make landscaping design beautiful, thoughtful, and well done. Always. Our Story Landscapes have fascinated Andrew Hammond, SLI's founder, as long as he can remember. From the time he could toddle, he spent his time outdoors collecting "specialmens" (as he called them). As he got older, his interest in landscapes grew into an obsession: he knew he'd found his life's calling. He knew he couldn't spend his time in an office. Wanting to get his hands dirty, he started Signature Landscape, specializing in creating beautiful landscapes for the next generation of "specialmen" collectors.
