我们制定了一个谋求将两个不同世界并列的计划。人造的和自然的。该计划有一个城市外观和野生自然的内部，每个空间包含一种不同类型的游戏。正式的外部是一个运动和有序的有序游戏的地方，而在野生内部，孩子们被鼓励和自由构建和毁灭他们自己的游戏空间使用天然材料。两个世界之间的边界“带”包裹和保护内部，同时适应外部以允许游戏并且集成传统的游乐场元素。
当地称为Deltaplantsoen的Grevelingenveld是Rivierenbuurt，海牙的一个邻里广场。 8.100平方米的空间设计与一个面向广场的新的邻里学校的发展仔细。操场概念将三种不同类型的游戏结合在一起成为一个整体;内部是一个野生的自然playcape，外部一个城市体育场，和两个被称为“丝带”之间的门槛是一个俏皮的建筑元素包含所有的传统游乐场设备。这种多样化的游戏类型被安排为开放式的playcape，创造一个丰富和动态的世界，提供儿童无尽的可能性的游戏和重新解释和重新想象的空间。相比之下，许多具有标准设备的单功能游乐场在今天各地都存在。

Play is about finding ones place in the world and making sense of that world. We have created a plan that seeks to juxtapose two different worlds. The man made and the natural. The plan has an urban exterior and a wild natural interior, each space contains a different type of play.?The formal exterior is a place for sports and structured ordered games, while inside the wild interior children are encouraged and free to construct and destruct their own play spaces using natural materials. A boundary “ribbon” between the two worlds wraps and protects the interior, while adapting towards the exterior to allow games and integrate traditional playground elements

Grevelingenveld known locally as Deltaplantsoen is a neighbourhood square in Rivierenbuurt, The Hague. The design of the 8.100m2 space links carefully with the development of a new neighbourhood school which faces onto the square. The playground concept brings three different types of play together into one ensemble; the interior is a wild natural playscape, the exterior an urban sports court, and the threshold between the two known as “the ribbon” is a playful architectural element containing all the traditional playground equipment. This diversity of playing types arranged as an open ended playscape, creates a rich and dynamic world that offers children endless possibilities for play and to reinterpret and reimagine the space. In contrast to the many mono-functional playgrounds with standard equipment that exist everywhere today.
