Dual Landscapes replaced an existing timber retaining wall with a Heron Block retaining wall (approx 30m in length). There were a number of technical and design challenges that arose throughout the project. Matt and Luke worked hard at identifying these issues in advance and communicated clearly what their professional recommendation was. This process was invaluable in keeping costs under control while ensuring the end result was a quality finish. Matt and Luke were also very accommodating with a number of variation I specified during the project. I would seek to use Dual Landscapes in the future, based on the quality of work, good communication and flexibility.
