Podčetrtek交通圈建在一个位于市政体育馆与一侧的露天运动场之间的区域公路，另一边有许多游泳池和酒店的水疗中心。它主要是为了减缓因此非常繁忙地区的交通，因为两个综合体的主要访问也连接到交通圈。因此，环形交叉路口的中心岛屿的设计参考了这两个设施的出现，并标记了进入任何一个方案中心的访客的目的地。

大型黑暗的混凝土块体现了体育馆的整体体积。在元素的不规则排列上的光的播放形成表面的组合，其对应于大厅的折叠体积的表达。回旋处内部的布局整体表明，地球表面下方的构造变化导致路面膨胀，并掀开了大块。

The Podčetrtek Traffic Circle is built on a regional road located between the municipal sports hall with open-air sports grounds on one side and a spa centre with numerous swimming pools and hotels on the other side. It is primarily intended to slow down the traffic in this consequently very busy area as the main accesses to both complexes also connect to the traffic circle. The design of the roundabout’s central island thus references the appearance of both facilities and marks the entrance points to the destinations of the visitors to either of the programme centers.

The large, dark concrete blocks allude to the design the monolithic volume of the sports hall. The play of light on the irregular arrangement of the elements forms a composition of surfaces, which corresponds to the expression of the hall’s folded volume. The layout of the inner part of the roundabout as a whole suggests a tectonic shift somewhere beneath the Earth’s surface having caused the road surface to bloat and belched out the massive blocks.
