Studio Vulkan：卡岑巴赫（Katzenbach）新住宅是苏黎世城郊总体改造的一部分，高密度的住宅取代了之前的“花园开发”项目。中央广场的设计语言源自住宅项目的整体逻辑，在中央广场的设计方案中，处于线性建筑之间的流动型开放空间有两种截然不同的类型和氛围，但二者并非完全独立，而是相互交替并产生对话。“树木庭院”可以看作是附近森林的一种延续，开阔的场地上种植着高大的落叶乔木，地面上光影交错。相应的，“开花庭院”位于地下停车场上方，那里只能种植一些体量较小的植被，这些小花园通过充分利用植物的色彩、种类和纹理重新诠释了联排住宅里的私人花园。

Studio Vulkan: The new housing for Katzenbach is part of a general transformation process on the edge of Zurich replacing older “Garden Developments” with high-density housing. The design language of the central plaza grows out of the logic of the overall housing scheme in which open spaces flowing between the linear buildings alternate between two contrasting typologies and atmospheres. The ‘Tree Courtyards’ continue the larger scale of the surrounding woods set forth with the play of light and shadow among high deciduous trees on an open ground plane. Alternating, the ‘Flowering Courtyards’ lie above underground parking where only smaller vegetation is possible. These gardens interpret the private gardens in the former Row House typology anew with a dense fill of vegetative colors, forms and textures.

中央广场是一个带有花园亭的游乐交流空间，设计方案遵循了“树木庭院”的逻辑原则。一种轻快的氛围跻身在住宅建筑的严谨布局之中，以树冠产生的光影为设计的中心思想，轻盈的树顶、垂直的树干和投射在地面上的阴影是设计的决定性因素，并响应设计的各种变化。

The central plaza, a play and meeting space with garden pavilion, follows the logic of the ‘Tree Courtyards’. Within the rigid placement of the housing buildings an ephemeral atmosphere is created using the play of light and shadow created by the canopies of the trees as the central idea. The light roof of leaves, the vertical trunks and the cast shadows upon the ground plane are the determining elements of the design, echoed in variations within the design.

广场的地面抽象地模拟了光影透过树木的投影，吸引用户在这样的空间中漫步。路面铺装则模拟了广阔的天空或者是华盖般的树荫，至于到底可以被看作什么，这便取决于观者的位置。座椅融入到树叶的空隙之中，带花边叶子的树木色板在各种深浅的绿色之间闪烁，形成一种朦胧的混合色调，使人很难一眼就分辨出不同色度的树叶（包括刺槐、金叶刺槐、金枝白蜡和樟子松）。树干恰好与亭子的暗色柱相呼应，环绕在树木之间攀爬网和垂直杆一同构成了游乐景观。

The ground plane of the plaza abstractly emulates the projection of light and shadow through the trees and animating users to meander through the space. A water plane level with the paving reflects the open sky or leafy roof depending on the location of the viewer. Seating elements dissolve themselves into the language of the voids between leaves. The palette of trees with their lacy leaves shimmer between various shades of green into a hazy mixture of tones difficult to grasp at a glance. (Robinia pseudoacacia, Robinia pseudoacacia ‘Frisia’, Fraxinus excelsior ‘Jaspidea’ and Pinus sylvestris). The tree trunks are echoed in the dark columns of the pavilion and play landscape made up of cables and posts winding between the trees.

设计师巧妙地将服务于不同人群的设施编织在广场中，比如攀爬架、沙滩和水、游戏元素、烧烤空间、秋千以及巨大的座椅元素，这些带靠背和不带靠背的座椅可供聚集在此的儿童和成人们休息交流。

A wide variety of uses for diverse user groups are woven inconspicuously into the plaza such as the climbing landscape, sand and water, play elements, grill space, swings, and enormous seating elements with and without back rests used for groups of children and adults to congregate.
