2012年6月初，由JMDd设计的Blaxland Riverside Park游乐场正式开放。为了扩大哈格里夫斯和他的伙伴们的娱乐机会，他们设计了新的游乐场和相关的信息亭、娱乐设施区和停车场。

In early June 2012 the JMDd designed Blaxland Riverside Park Playspace was officially opened. The new regional scale playground and associated kiosk, amenities block and car park were commissioned to expand the recreational opportunities of the Hargreaves and Associates designed Blaxland Riverside Park, one of a number of parks that make up Sydney Olympic Parklands.

JMD设计将哈格里夫斯和他的伙伴们建立的圆锥体、切割和梯田的主要地形合并在一起，设计了一个独特的新项目，该项目与它的环境保持对话。在现有的梯田上方，有一个200米长、3米高、重复着哈格里夫斯梯田的几何形状的高坡。新平台被挖掘成倾斜的平面和倒转的土丘，为移动和玩耍创造空间。

JMD design conflated the dominant landform of cones, cuts and terraces, established by Hargreaves and Associates to design a distinctive new project that maintains a dialogue with its context. A 200m long and 3m high berm  that repeats the geometry established by the Hargreaves terraces was inserted above the existing Terraces. The new terrace was excavated into with tilted planes and inverted mounds to create space for movement and play.
