** BASE FLOOR ** - the stacked public park The green base of the building forms a public vertical park. A wide range of social, commercial and cultural opportunities are integrated into the “green framework”. The green base literally forms the basis for the house community: A place of arrival, departure and encounter; it is a comprehensive part of the everyday life of all residents and at the same time forms the link to the neighborhood. With small shops, cafés and space for cyclists, the layered garden opens up towards the Schöneberger Strasse and the northern passage towards the cultural venue “Tempodrom”. Diverse open spaces allow encounters and exchanges. A generation cluster is being created in the base area with a daycare center, music studios, library and market hall. Climate-active, public, social, multidimensional: the vertical park will be the prototype for a new type of open space for Kreuzberg and Berlin.

BUILDING - A Kreuzberg building kit: modular, flexible and mixed! The clearly form of the timber high-rise building is located in the middle of the green base zone. The building reaches a total height of almost 100 meters and is complemented by a public pocket park on the top floor. By stacking the typical Berlin housing block, a clearly structured mixed-use high rise building will be created. There is a coexistence of residential property, rented and subsidized apartments on each floor. Each block is supplemented by two semi-public so called “Kiez floors”, which can be connected to the common rooms on the residential floors and ensure a typical mix of Kreuzberg. The residential floors can be individually inhabited by means of a "housing kit" and the “Kiez floors” are flexible for various semi-public uses through the "Kiez housing kit". The building becomes a stack of democratic spaces that permit the inhabitants to define their use flexibly.

** THE VERTICAL KIEZ ** - Promote community: Use the vertical potential of the high-rise typology The Kreuzberg “building kit” provides the basis for a high degree of diversity, both in the public and in the inhabited part of the tower. This high density and the social diversity of users represents a potential for the vertical neighborhood. The idea of a vertical neighborhood is taken up at various points in the tower: spaces resulting from the multi-storey situations function as meeting areas. The mix of uses on multi levelled public spaces starts in the base. All levels of the building can be reached and linked with one another via the park. In addition, the offset arrangement of the balconies on the residential floors offers the possibility of communication between the residents across the floor. Multi-storey communal areas also offer the option of bringing the public neighborhood area and the living area together and enable a wide variety of groups to use larger rooms. The topic of verticality is also taken up on the roof terrace and combines the café area, viewpoint, staircase and urban gardening on different levels.
