McGregor Coxall于2011年被澳大利亚委托与他们合作，在38.5公顷的场地（即Ashlar高尔夫球场）开发一个拟建的住宅发展的景观总体规划。该地点位于布莱克敦，靠近中央商务区和两个大型工程排水系统的汇合处。植被在遗址上由一个独特的保留地方性树种的生态系统组成。澳大利亚聘请McGregor Coxall，其具体目标是利用我们的整体方法对水敏感的城市设计和现场反应。与许多专业顾问合作，McGregor Coxall开发了一种设计响应，对排水系统进行设计，使其成为拟建新社区身份和开放空间网络的关键组成部分。这一战略是通过建立两个主要的水基公园，通过一个激活线性湿地环境走廊相互连接，促进野生动物的运动。

         McGregor Coxall were commissioned in 2011 by Australand to work with them to develop a landscape master plan for a proposed residential housing development on a 38.5ha site, formally known as the Ashlar Golf Course. The site is located in Blacktown in close proximity to the CBD and at the confluence of two large-scale engineered drainage systems. Vegetation on the site consists of a unique ecological system of retained endemic tree species. Australand engaged McGregor Coxall with the specific aim of utilizing our holistic approach to water sensitive urban design and site response. Working in collaboration with a number of specialized consultants McGregor Coxall developed a design response that de-engineers the drainage systems so that they become a key component of the proposed new communities identity and open space network. This strategy is realised through the establishment of two major water based parklands, which are interconnected through an activated linear wetland environmental corridor that promotes wildlife movement.
