办公室改建为住宅。曾经是一家国家银行的总部，现在是一座住宅楼，是阿姆斯特丹新的充满活力的街区Westerpark West的起点。大象将城市生活翻了个底朝天，将经典的住宅塔楼彻底改变。

Office to residential conversion. Once the head office of a national bank, now a residential tower and the starting point of a new vibrant neighborhood Westerpark West in Amsterdam. Elephant has turned city life inside out and changed the classic residential tower for good.

为改变而设计的无芯循环。典型的改造不会带来高质量住房的雄心壮志，我们决定将核心部分分成四部分，并将电梯重新布置到外墙。楼梯被放置在露台之外，成为建筑的一部分。以前的混凝土循环核心被改造成用于浴室、存储和技术空间。因此，我们称这种新的循环概念为无核心，现在也被用于新的住宅塔楼。

Designed for change with the Coreless circulation. A typical transformation would not have resulted in the ambition of high-quality housing, we decided to split up the core into four and reposition the elevators to the facade. Staircases are placed outside the terraces and become part of the architecture. The former concrete circulation core is remodeled to be used for bathrooms, storage, and technical spaces. Hence we called this new circulation concept Coreless and is now also being used for new residential towers.

居民与每层楼只有一个邻居共用一部电梯。当离开电梯时，你进入一个可以看到公园的走廊。走廊可以直接通向公寓和它们相应的私人露台。一个公寓的露台连接到所有的个人生活空间。这使得该建筑的使用和配置是无止境的。无核心概念使总面积和净面积之间的比例非常有利。这也对所需的建筑材料以及能源管理产生了积极影响。

Residents share an elevator with just one neighbor per floor. When leaving the elevator, you enter a hallway with a view of the park. The hallway gives direct access to the apartment and their corresponding private terraces. An apartment’s terrace connects to all the individual living spaces. This makes the usage and configurations of the building endless. The Coreless concept results in a very favorable ratio between gross and net floor area. This also has a positive effect on required building materials as well as energy management.

最具可持续性的仪表是不需要建造的。巨大的私人露台被称为 “前花园”。除了新的流通概念，大象提出的三米深的露台与建筑和新的全玻璃外墙一起。这两个元素都大大提升了公寓的品质。

The most sustainable meter is the one that does not have to be built. Huge private terraces are called “Front Gardens”. In addition to the new circulation concept, Elephant proposed three-meter deep terraces along with the building and a new full glass facade. Both elements enhance the apartment’s quality greatly.

新增加的露台连同其功能元素；如楼梯、花盆和栏杆，成为主要的建筑特征。玻璃外墙不再是建筑的一个重要载体。这为高度灵活的外墙奠定了基础。居民们参与选择他们的配置，现在已经建成了，仍然能够改变它。

The newly added terraces together with their functional elements; like staircases, planters, and balustrades, became the main architectural feature. The glass facade became less of an important vehicle of the architecture. This established the basis of a highly flexible facade. Residents were involved in choosing their configuration and are still able to change it now that it has been built.

多功能的综合种植槽。在整个建筑中，120棵树散布在梯田上。大象希望这些树能与户外空间的体验融为一体。这导致了将树木基质置于露台之下，作为标志性的树木种植槽柱。这些花盆是与植被设计师、树艺师、园艺师、结构工程师和业主协会一起合作开发的。

Multifunctional integrated planters. Throughout the building, 120 trees are scattered over the terraces. Elephant wanted the trees to become one with the experience of the outdoor spaces. This resulted in placing the tree substrate underneath the terrace as the iconic tree-planter columns. The planters are developed in collaboration with vegetation designers, arborists, gardeners, and structural engineers together with the owners’ association.

这些容器配备了必要的技术，使树木能够在高处生长。一个自动灌溉系统和一个园丁负责维护。这种激烈的合作导致了一个绿色建筑，每棵树的维护成本比例仅为30欧元/年。

The containers are equipped with the necessary technology to allow a tree to grow at height. An automatic irrigation system and a gardener take care of maintenance. This intense collaboration resulted in a green building with a proportional maintenance cost of just €30/year maintenance costs per tree.
