为了应对人口结构的变化和年轻居民数量的增长，Differdange市发起了在老足球场上建造该市第四座青年活动中心的可行性研究。之前的三座青年中心均设在已有的房屋或公寓室内，与之相对，新的青年中心将是一栋全新的建筑，需要在有限的预算下完成。
In order to respond to demographic growth and the number and density of young inhabitants, the city of Differdange launched a feasibility study for a fourth youth center, implanted on the old football field of the city. Contrary to the existing three, organized inside existing houses or apartments, this center would be newly built, but on a limited budget.

经过对供需的研究探讨，设计提出了以空间使用性为主题的概念。建筑将作为教学工具，作为个人发展的手段，同时作为基础设施，服务于市民生活。
As a result of a consulting phase studying demand and supply, a concept was developed proposing the availability of space as main theme; as pedagogical tool, as means of personal development, as an infrastructure for civic life.

冬天，仅在核心功能区设置采暖。这些功能设置在由质量木材制造的家庭尺度空间盒子中，配以当代标准的保温结构。这些盒子被包裹在一个工业尺度的聚碳酸酯外壳中，盒子与外壳之间形成了巨大的空间，可用来举办体育、休闲或文化活动。
In winter, only the core functions are heated. These functions are located in domestic-sized spaces, boxes built out of massive wood, and insulated to contemporary standards. The boxes are protected by an industrial-sized polycarbonate shell, that generates extra space able to host sports, leisure or cultural activities.

从春到秋，围合用的玻璃车库门升入天花，使得盒子空间可以完全面向外壳开放。
From spring to autumn, the boxes can completely open up to the shell via glazed garage doors that vanish on the boxes’ ceilings.

建筑避免了任何形式的完成面的使用，没有抹灰，没有涂料，也没有砂浆，有的只是必要的结构及其品质。借此，在基本同等的预算下，中心的使用面积是通常建筑的三倍。
The architecture avoids all kinds of finishing: no plasterwork, no paint, no screed, only the structurally necessary is built and qualified. Thus, the surface of the center tripled in size, roughly on the same budget.

最终，设计创造了一个独一无二的市民中心，既是年轻人的家，也是一个所有居民都可以享用的多功能空间。
The result is a one-of-a-kind civic center, a house for young people, a polyvalent tool for all citizens.
