荷兰威乐公司的核心业务是生产水泵，这启发了该公司大楼的设计：一个由焊接铝外墙包裹的管状体和一个壮观的水面上的倾斜悬臂。该建筑是Westzanerpolder的Hoogtij商业园的首批开发项目之一。
Wilo Nederland’s core business in manufacturing water pumps inspired the design of this company building: a tubular volume wrapped by a welded aluminum facade and a spectacular sloping cantilever above the water. The building is one of the first developments in the Hoogtij business park in Westzanerpolder.
端部外墙是通往前院和水面的代表性外墙，并尽可能地透明。相比之下，侧面的外墙更加封闭，可以防止Westzanerweg上的交通噪音。该建筑的形式和材料为这条道路增添了额外的活力，并增强了过往驾驶者的体验。
The end facades are the representative facades to the forecourt and the water and are as transparent as possible. By contrast, the side facades are more closed and protect against the traffic noise on the Westzanerweg. The form and materials of the building add an extra dynamism to this road and enhance the experience for passing motorists.
屋顶是由轻型的异型钢板制成。为了享受混凝土的好处–防止室内快速升温和过热–钢板上的凹槽部分被混凝土填满。两根管道穿过每个凹槽中的混凝土，用于冷却，必要时用于加热，此外还有地板上的主加热系统。为了配合完整的混凝土屋顶的积累能力，设计师使用了一种特殊的混凝土混合物。在混凝土中加入带有石蜡的谷物，意味着可以储存多余的温暖而不影响材料的温度。板材的上表面是穿孔的，并安装了隔音材料。其结果是：一个轻质的屋顶，具有混凝土的积累能力和良好的声学特性。
The roof is made of light, profiled-steel sheeting. To enjoy the benefits of concrete — preventing rapid warming and overheating of the interior — the grooves in the steel sheets are partly filled with concrete. Two pipes, channelled through the concrete in each groove, provide for the cooling and, if necessary, heating, in addition to the main heating system in the floor. To match the accumulative capacity of a complete concrete roof, the designers used a special concrete mixture. The addition of grains with paraffin wax to the concrete means that excess warmth can be stored without affecting the temperature of the material. The upper surface of the sheet is perforated and fitted with acoustic insulation. The result: a lightweight roof with the accumulative capacity of concrete and good acoustic properties.
