Matthäus街区作为Kleinbasel工人的居住区，仅有将将十年的历史。在1890到1900年间，这里由快速建造起来的统一住宅体块组成。与许多其他后院一样，该住宅后部直接与一间小型手工工作坊相连。多年来，这栋双层住宅发生了许多变化。现在，业主希望对其进行扩建，创造新的有顶空间，作工作室和客房使用。

The Matthäus- neighbourhood was built in hardly more than a decade as a residential district for the workers of Kleinbasel. Between 1890 and 1900 a district characterised by uniform housing blocks was built within a short period of time. As in many backyards, a small craft workshop was established directly behind the residential building. The two-storey house has already undergone several changes over the years and is now being extended to create additional space under the roof that can be used as a studio and a guest room.

在保留屋脊和檐口轮廓的基础上，建筑师打通屋顶，创造了一个空间更高的新房间和一条带形窗。原有的材料被重新利用。地板和框架以新的外观成为改造后住宅的一部分，将其带入了下一个使用阶段。扭曲变形的梁板被拆除，经过切割和打磨后重新置入空间，依然可以被人们看到。它们与精细的预制胶合板交替出现，其斑驳的表面和裂痕展现出了时光流逝的痕迹。室外，优雅的波纹锌板与后院中的半工业半永久建筑产生连接。

While retaining the ridge and eaves lines, the roof was opened to create a new room with more height and a new ribbon window. The existing materials were adapted and reused. The floor boards and the framework remain part of the changed house and – in a new guise – take it into the next phase of life.  The warped and skewed beams were also dismounted, cut, brushed and reinserted to remain visible. Alternating with the precisely prefabricated plywood panels, their notches and cracks reveal traces of times gone by. On the outside, the finely corrugated zinc sheeting seeks to connect with the half-industrial and half-ephemeral buildings of the backyard.
