In the historical part of the Lower Libeň neighbourhood, city blocks built according to Prague’s urban development regulations mingle with fragments of the old Jewish town and modern solitary buildings; this is the environment for which we designed a new residential building on Zenklova Street, in proximity to our previous, larger project: the permeable Palmovka Park block. We chose the form in such a way as to create a sort of transition, integrating the diverse elements which make up the character of the place, and following on Libeň’s functionalist tradition. The volume of the new structure rises from the footprint of the original buildings; on a symbolic level, a pedestrian path traces the now-vanished Jirchářská Street, and it is possible to walk through the ground floor of the new building. Taking into account the visual diversity of the surrounding space, the design uses a simple unifying feature for the somewhat fragmented mass of the building: rows of windows and shop windows of different lengths and heights, a feature seen frequently in “city palaces” from the first half of the last century. The shape of the plot allows for a more generous spatial arrangement of the building volumes, including a central lobby. Instead of just housing conventional stair sections, the lobby is an authentic central hub, a meeting point for the residents, and a place offering the everyday experience of a distinctively modelled and lighted space. Vistas, shapes rich in detail and plays of light may bring to mind the poetics of staircases in old apartment buildings with their generous dimensions and stained-glass windows, or remind one of the vanished corners of old Libeň.
