建筑的设计遵循这样一个原则 ， 即ISMO的工作人员能够在建筑中享受工作过程 ， 他们就似乎漫步在建筑周围的公园与森林之中 。 因此 ， 该项目代表了城市与乡村布局的融合 ， 并且在全新的混凝土结构中融合了起伏的山坡景观 。 从Rue André Rivière至前侧院落有着一段宽阔的台阶与坡道 ， 地面上铺设着混凝土砖 ， 让整座建筑充满意大利宫殿的气息 。

A basic design principle has guided the Dutch firm: that ISMO staff should be able to experience their journey to and through the building like a walk in the park and the ancient forest surrounding the building. In fact the project represents an exemplary integration of an urban-meets-rural layout with the new concrete structure emerging from the forest within an undulating landscape of rolling hills. A broad flight of steps and a ramp wind from Rue André Rivière to a forecourt. Both are paved in concrete tiles giving the whole ensemble the charm of an Italian palazzo.
