Who we are

Before beginning any design we apply a process of thorough site analysis. It’s a tool that we have developed and refined through more than 15 years of experience and we know it makes a difference. After meeting with you the client to discuss your objectives, our first step is to take an inventory of the natural elements of the site – it’s history, orientation to sunlight and views, natural drainage, traffic patterns, and plant materials. This allows us to identify complements and potential conflicts in regards to defined goals. From this initial process of evaluation we are able to make conclusions based on our analysis. Then we design, with the end result being an environment that is complimentary and that avoids conflict with both the setting and your individual goals. Contact us today to see what we can do for you.
