"We have been working with dsquared now for over two years across a range of sustainability related activities. One of their main strengths is the breadth of knowledge and expertise that Paul, Deborah and team bring to our projects. The quality of their work is excellent. They are trusted advisers to me and my team".

“Paul and Deborah at dsquared have been instrumental in assisting Renewal SA at Bowden and our clients change their way of thinking about how Green Star can be employed and done so in a commercial context. In an economic environment where developers are seeking to cut costs and protect margins and government is still trying to lift the bar on design, dsquared have assisted in communicating the benefits of Green Star but also providing a legible path through it".
