这是由baumraum设计的城市树屋。这是一项家庭项目，基于祖父Hans-Joachim及其孙子Kolja的愿望。这是新建筑实践与研究项目，试图与自然相互协调。该项目旨在成为一个绿洲，招待亲友以及对建筑学感兴趣的学生和游客。树屋通常位于农村环境或自然环境，而该项目是位于柏林的城市环境。建筑师期望通过这个任务为柏林建筑传统文化作出贡献。

树屋占地面积相对较少，因此，充分利用可建设用地面积在这里并不适用。而保护这个650平方米的花园的树木是该项目重要的关注点之一。在多个方案比对研究之后，设计提出了两个立方体的单元，分别为21平方米的居住空间。两座建筑体盘旋着高基地而设，并在同样高度配置了一个有屋顶的户外表皮，以及一个标高为2.6米的低处平台。其中一个树屋，中间楼层以及楼梯使用了灵活的悬挂物支撑着。建筑的配套、花园辅助储藏室与垃圾用房位于裹以落叶松木板的建筑底层。建筑为承重结构，支撑和框架部分使用了镀锌钢材。而墙壁、天花板和地板则使用了坚固的预制五层云杉面板。这种材料的结构和生态品质良好。这些坚固的木材还能隔热、透气、蓄热，能快速而方便地进行安装。

From the architect. The Urban Treehouse is a family project and is based on the initiative of the grandfather Hans-Joachim and his grandson Kolja, who ultimately mimplemented the project. Once more, it is conceived as an experiment and a research project for new construction and housing in tune with mnature. It is intended to serve as an oasis and inspire friends and guests of the family, as well as students and those interested in architecture. We were very enthusiastic when the developer, Kolja Stegemann, approached us with the idea of implementing treehouses in the urban environment of Berlin. Treehouses are normally associated with a rural environment or natural surroundings. Thus, such an undertaking is somewhat rare and very appealing for a planner. In Berlin, one is in good company with regard to small, extraordinary buildings. Here, there mare many alternative projects, which often with small budgets occupy niches in the city. As planners, we looked forward to contributing to mthe tradition of architectural culture in Berlin through this task.

The district of Zehlendorf is characterised by somewhat bourgeois residential buildings with larger properties and gardens. There are not many multi-storey residential buildings here, unlike many other parts of Berlin. The spezial feature of the site lies in its outstanding location. Bordering the forest, it is located in the immediate vicinity of the beautiful lakes of Krumme mLanke and Schlachtensee. The fact that this land was not built on earlier is surely a stroke of luck mand is certainly due to the specific demands of the family. The treehouses were to cover a relatively small proportion of land. Thus, the usual requirement of using the last available square metre profitably does not apply here. Of course, the preservation of the tree population on the 650 square metre garden property was one of the essential concerns of the developer.

After studying various designs, two cubic units were created – each with 21 square metres of living space. Both buildings hover on a fourmetre high base and are equipped with a covered exterior surface at the same height, as well as a lower terrace at a height of 2.60 metres. For one of the treehouses, the intermediate level and both flights of stairs are supported by flexible suspensions from the oak. The building’s utilities, supply circuit and storage space for garden tools and waste are located in the base that is lined with larch slats. The load-bearing design, supports and frame above it consist of galvanised steel sections. Solid prefabricated five-layer spruce panels are used in the walls, ceiling and floor. The advantage of this construction lies in its structural and ecological qualities. These solid wooden parts have a high insulating quality, are breathable, have a high heat storage capacity and can be installed quickly and easily. The rear-ventilated fa.ade consists of aluminium composite panels. Depending on the angle of the light, this can result in a vivid interplay of colour on the outer envelope of the buildings. The interior provides everything one could possibly need: a bathroom with a shower, a lightflooded interior featuring a kitchenette and comfortable bed, as well as some beautiful home accessories. When it comes to the wall and ceiling panels, the solid wood spruce panels have been left visibly in their natural state.

The Urban Treehouses are places that enrapture, inviting one to play and reflect and what is more, to look at things objectively and change perspectives in other words, these are inspirational places to gather strength. The two treehouses are situated precisely at the transition from city to countryside and thus connect both worlds – vibrant Berlin with restorative scenery. Shortly before the start of construction, Hans- Joachim Stegemann died in old age. Unfortunately, he was not able to witness the completion of the treehouses and the development of his idea to build something unusual on his land. The treehouses are dedicated to him and his wife. We would like to thank Hans-Joachim Stegemann and his grandson Kolja for this beautiful project.
