35个挑战世俗的青少年居住在Brüttisellen的职业培训中心，他们还要在此休闲娱乐。

由于该5/10/5米运动馆附属建筑和两个相邻的健身房的建造，它们的休闲活动的范围大大增加。通过对既存健身房的双重使用，新建筑的体积已经是原主建筑的两倍大。

由于该建设的主体下沉到地面3米以下，其扩建部分堵塞了中央公园到道路的部分。其当代设计作为发展的象征。

分别代表了2006年到2011年之间完成的扩建建筑。新开发的部分包括管理，住宿团体，教学和休闲，构成了该建筑至今为止的所有时期，并升级为体现新获得的自由空间的体育中心体。

新建筑四周的窗口满足了游客的好奇心，他们想知道（也被允许知道）该建筑有哪些功能。

其外观变得透明，并能看到院子里的景色。在喧嚣的夜晚，人工的灯光点亮了该建筑新建的中间点。

该建筑四周的窗户将建筑刺穿，只有少数精制混凝土支撑着减少的负载和屋顶的支撑。

其静力系统没有固定的网格尺寸，而带有不同梯度的混凝土柱，这是建筑理念的一部分。建筑物整体包括屋顶在内的外表，只采用了混凝土和玻璃材料。

其原混凝土广泛应用于外观、静力系统、抗震、防潮。其内部防潮、隔热、隔音和木质的坚固表面体现了其内部核心的高效节能。完全体现了其成熟的概念 - 坚硬的外表、温和的核心。

其室内木镶板选自法国耶路撒冷或阿勒颇松树的大型胶合板。为了获得最佳的声觉效果，其85％板材都需要穿孔。室内房间内分布着大约40平方米表面非穿孔板材，从而产生穿孔和非穿孔板材之间的对比。

Thirty-two socially challenged youths live in the occupational training home in Brüttisellen where they also must spend their leisure time. The range of leisure time activities has been increased through the development of the 5/10/5 metre sport hall annex and the two adjoining fitness studios. Through the double use of existing adjoining rooms, the volume of the new building has been coupled with the main building.

As a flat building with the main body sunk 3 metres into the ground, the extension closes the central garden courtyard off into an access road. The contemporary design stands as a symbol for the development, respectively for the accomplishment of the buildings development between 2006 and 2011. The newly developed ensemble with administration, accommodation groups, schooling and leisure comprises all the building stages up until now and is upgraded to a centre embodied in a newly acquired free space.

The circumferential window band of the new building shows the curious visitor under the spell, one wants (and is allowed) to know which function underlies this building. The façade becomes transparent and a view in the courtyard is desired. With the evening bustle artificial light supports the meaning of the newly articulated middle point of the home.

The building is punctured through the circumferential window band, only a few precisely-assembled concrete support columns take over the reduction of the load and the bracing of the roof. The statics system, without a fixed grid dimension and with differing gradients of the concrete columns, is a part of the architectural concept. The total outer shell of the building, including the roof, is reduced to the materials concrete and glass. The raw concrete is façade, statics, earthquake resistance, moisture proofing and robust all in one. The interior with its moisture barrier, insulation, soundproofing and a sturdy surface in wood is the energy-efficient quick reacting inner core. Totally within the proven concept – hard outer shell, soft core.

The interior wooden panelling is from large-sized plywood boarding of French Jerusalem or Aleppo pine. To achieve an optimal acoustic, 85% of the boarding needed to be perforated. The non-perforated surfaces from approximately 40m2 were distributed through the room, so that a spiel between perforated and non-perforated boarding was generated.
