1  I have known Ben since the early days of The Currumbin Ecovillage, when he worked with Landmatters as a Project Manager. Since that time, Ben has had many other roles in the environmentally sustainable design (ESD) industry, and assisted my architectural practice, degenhartSHEDD, with a Material Change of Use application for Labrador Park Urban Village while he was the Queensland State Manager of Cundall. Ben has always been passionate about taking an efficient and cost-effective approach to sustainable design, and embeds the values of his professional expertise in both his business and personal life. Ben is a “go to” guy, and has risen to many a challenge with absolute professionalism and exacting precision, though his penchant for innovation is often what delivers his results-oriented outcomes. I am very happy to recommend Ben, and know that he will make the best of all opportunities afforded to him to craft a better world.”
