德国奥伯豪森行政大楼 · 砖与绿的奇妙张力

这座位于奥伯豪森（Oberhausen）中心地带的办公大楼以一种全新的方式，将公共行政大楼的多种功能与屋顶花园相结合，打造出一个兼具两种风格的建筑体量。砖砌建筑体量的厚实感与绿色花园的轻盈感共同创造出一种奇妙的张力，不仅赋予这座大楼一种极强的可识别性，更潜移默化地影响着奥伯豪森市内的重要区域——Altmarkt的城市环境和肌理。

The office building in the center of Oberhausen combines the diverse functions of a public administrative building and rooftop garden in a new way, integrating features of both typologies. The tension between the physicality of the brick building and the delicate lightness of the greenhouse creates a new identity that affects the urban context of the Altmarkt, an important location in the city.

垂直花园将地面上的广场与屋顶上的花园在竖直方向上联系在了一起。本项目由建筑事务所Kuehn Malvezzi与景观设计事务所le balto合作完成，作为一种高效的城市规划元素，它不仅有目的地将新旧景观类型结合在了一起，更创造出一个新型的公共空间。多样化的交通流线引导着来访者们从地面上到屋顶：从绿树成荫的市场广场通过台阶向上走，经过一系列平台空间和休息空间，在藤蔓植物的陪伴下来到屋顶花园。置身于屋顶花园，人们可以欣赏到城市离市中心一览无余的景色。

A vertical garden connects the square with the roof garden. Developed in collaboration with landscape architects atelier le balto, it is an effective urban planning element that purposefully combines the old and new landscape typologies as a public space. A varied course leads visitors from the tree-lined market square up steps and platforms, past climbing plants and seating areas, to the roof. From the rooftop, the view opens up over the historical center of the city.

此外，建筑事务所Kuehn Malvezzi还与Haas Architekten合作，对屋顶的部分温室进行规划布局，将其作为奥伯豪森的弗劳恩霍夫环境、安全和能源技术研究所（Fraunhofer Institute for Environmental, Safety and Energy Technology）的实验区，以实现一种农业和建筑一体化的概念。

A part of the rooftop greenhouse which was planned in cooperation with Haas Architekten is a research area used by the Oberhausen-based Fraunhofer Institute for Environmental, Safety and Energy Technology, to realize its concepts in the field of building-integrated agriculture.
