Upcycling – further developing the city.
Sustainable urban development also means carefully weighing and further developing existing structures. City needs grown density and the chance to develop. The individual neighborhoods therefore bear the signature of the existing surroundings and railroad fragments. They anchor themselves in the city’s history and develop from there individually and according to their genetic code.

Track curves – Life emerges at the edges.
At the same time, city needs distinctive landmarks where urban life can crystallize. Planning can hardly anticipate this development, but community life often emerges at borders and transitions. Through its topography, the Gleisbogen formulates the transition from city to green space. The empty flyover structures, the gently rising promenade above the treetops, the sports fields at the edge of the Volkspark or the cultural islands offer a multitude of possible crystallization points. The track arch defines itself as a permeable boundary where public life can take place. Its shape itself remains changeable and will adapt to the needs of future generations. The track arch is the visible sign of a new sustainable urban society in the heart of Europe.

PlusEnergy – climate-neutral in the long term.
PlusEnergy offers a great design opportunity. Green facades and solar panels shape the appearance of the buildings. The buildings are rooted in the earth, storing surplus energy in the ground. Cooling in summer, heat in winter. Greened through and glittering, the ribbon of the climate-neutral city rises above the treetops of the Volkspark.

Urban climate – beyond the neighborhood.
In addition to efforts to prevent extreme climate change in general, it is also important for buildings designed for long lifetimes to minimize the consequences of potential climate change. Dense buildings and a lack of vegetation can lead to the undesirable “heat island effect” in cities. To avoid these “hot spots,” extensive green spaces are therefore included in the planning, following nature’s example. On the one hand, the public park provides shading and evaporation areas and thus acts as a regional cold generator. On the other hand, green roofs and facades in the built-up areas cool and purify the air in the new urban quarter.

Flexibility – varied and mixed.
Because of the long lifespan of buildings, we need to think beyond functional layouts that are tailor-made for today’s needs. City must consist of buildings that are neutral in terms of use on their surfaces and can be used for both working and living, in small groups as well as large communities. The first floor zone must provide space for contact between the public and the private. This includes large-scale halls for production and commerce (vertical factory) as well as the careful design of small-scale front zones. Culture and education weave themselves into the urban body.

Housing – affordable and fair.
Social coexistence must not be jeopardized by the fact that sustainable housing is not affordable for all. Where it makes sense, standards should be questioned. The new neighborhoods should become European Werkbundsiedlungen: Fields of experimentation where these challenges are addressed. The development costs for climate-friendly economies must be distributed fairly.

Mobility – Sharing Economy.
Mobility will undergo a profound transformation in the medium term. The new neighborhoods are designed to provide parking for about 20% of today’s car volume and large-scale and conveniently accessible e-bike parking spaces under the buildings. All parking spaces are equipped with solar power charging stations from the building’s own production. Change takes time. Temporary neighborhood garages therefore buffer the need for space for individual cars during the transition period. They are designed in such a way that they can be converted into living and working spaces in 20-30 years and do not have to be demolished. Above-ground mobility points are available for visitors and guests in public spaces. They are the meeting places and marketplaces of the future.
