20世纪70年代的现有建筑是一个定居点的一部分，它受到相同建筑类型的房屋的影响。这些原型的放置或多或少没有考虑到它们的方向、地形或隔壁房屋的位置。由于有两个外墙是没有窗户的，这所房子让人更多地想起排屋而不是独立的房子。除此之外，这栋房子还缺乏一个适合当代生活的功能性平面图。
The existing building from the 1970s is part of a settlement, which is affected by the same building type of houses. These prototypes are placed more or less without regard to their orientation, the terrain, or the position of next-door houses. As two of the facades are windowless the house reminds more of a row house than of a free-standing house. Besides this, the house lacks a functional floor plan for contemporary living:
窗户小或缺失，主楼被分割成小房间，浴室的安排也很复杂。内部停车库似乎不合时宜，以及通过楼梯平台的通道。花园朝向北方，小型阳台几乎无法使用，也没有与生活区连接。
Small or missing windows, the division of the main floor into small rooms, and the complex arrangement of the bathrooms. The internal parking garage seems out-of-time, as well as the access via the landing of the stair. The garden is orientated to the North, the mini-balcony is hardly usable and is not connected to the living area.
新的方案用一个工作室取代了车库，现有的入口被修改，以利于从南边的慷慨访问。由于不需要承重墙，屋顶的建设使得整个上层楼面得以重组。生活区现在连接着南部的扩展阳台和北部的花园景观。
The new program replaces the garage with a studio, the existing entrance is modified in favor of generous access from the South. The construction of the roof enables the reorganization of the total upper floor as no load-bearing walls are required. The living area now connects the extended balcony in the South with the garden view in the North.
为了不超出预算，我们建议采取一些结构性措施。现有的屋顶保持不动，地板用OSB覆盖。所有的护栏都被拆除，以产生图片窗，并最大限度地增加光线入射–而不改变结构系统。
In order to stay within the budget a few structural measures are made advisedly. The existing roof stays untouched and the floor is covered with OSB. All parapets are removed to generate picture windows and maximize light incidence – without changing the structural system.
新的垂直分割的窗户强调了现有正面的垂直外观及其阳台框架的墙。在房屋内部，垂直方向被房间高的推拉门所延续。
The vertical appearance of the existing front facade with its balcony-framed walls is stressed by the new vertically divided windows. Inside the house, the vertical orientation is continued by room-high sliding doors.
标准的钢格栅保证了上层的防坠落保护—在底层，出于安全考虑，钢格栅被固定。阳台也是用钢格板包覆的，没有底层结构。所有的木制窗框都是灰色的玻璃。建筑物采用矿棉隔热材料。粗糙的外观与周围的省级环境相悖，显示了房屋的根本改造。项目的时间安排不到一年。
Standard steel gratings guarantee fall protection on the upper floor – on the ground floor they are fixed for security reasons. The balcony is clad in gratings without a substructure as well. All wooden window frames are glazed grey. The building is insulated with mineral wool. The rough outer appearance rebels against the provincial surrounding and demonstrates the fundamental transformation of the house. Time schedule for the project was less than one year.
