苏黎世Hirzenbach区域的城市结构如同花环般层次分明，外围的公寓楼高低起伏，环绕着中间开阔、平坦而低矮的学校建筑。而由Basler & Hofmann事务所所新建的建筑意在加强现有城市肌理的逻辑关系，学校建筑的北侧建起了仅有一层高的幼儿园，而南边的半下沉体育馆则充分考虑了其作为开放性公共空间的通透性。新建建筑与现有的学校建筑在空间与造型上相互呼应，充分表达了建筑师对现状的尊重，同时也重新整理的外部空间的结构，三座建筑之间的室外场地将被用作室外活动场地、游戏场地或是安静的休息场地使用。
The development structure of the perimeter in Zurich Hirzenbach as in Wasserfallen’s area-development plan is characterised by a peripheral garland of apartment blocks of varying heights, stepped towards each other around a middle occupied by a flat, solitaire school building. The new configurations aim to reinforce the existing urban-planning logic. The existing school building is expanded to the north by a single-storey kindergarten and to the south by a half-sunken sports hall with due consideration for the permeability of the open space and the low-rise development of the middle. By showing a typological affinity the new buildings continue to respect the existing school as the main building, whilst within their respective positions naturally re-ordering the exterior space into the functional areas of motional, play or intimate zones.

The two new buildings interlock with their encompassing space via the massive brise-soleil frames developed out of the block. In the process a spatial formulation of the structural skeleton construction of the existing school building is articulated in a functional charging: the transitional layer protects against glare in the sports hall and becomes an intimate balcony space for the kindergarten. The deep ‘frames’ serve the requirement for protection and simultaneously for the greatest possible openness, becoming both an adaptive and viewing space within the large-scale surroundings.
