The new green quarter is founded on principles of ecological, economic, and social sustainability. A strong focus on rainwater management ensures a well-conceived blue-green infrastructure with accessible open spaces. Wind and green corridors, along with green roofs and facades, create an optimized microclimate. To enhance environmental compatibility, the quarter will be constructed using serial prefabrication and recyclable materials. The supporting structures of the buildings make sensible use of wood as a renewable resource. From the outset, embodied emissions are minimized, and, during use, the buildings act as CO2 reservoirs. The energy supply is self-sufficient, powered by geothermal and solar energy. Integrated planning combines biodiversity with a circular economy and aims for CO2 neutrality. This green, vibrant district is set to regenerate, reduce, and recycle, evolving into the sustainable neighborhood of tomorrow.

The friendly and welcoming reception center is a sustainable timber hybrid building with a clear vertical structure and a transparent base. This is where the arrival and transfer procedures are conducted, and federal and state registration and health checks take place across 4 floors. The complex flow of visitors is efficiently managed by separating individual areas, with an escalator ensuring optimal movement to the heavily frequented first floor. Spacious elevators and an open staircase provide access to the upper floors. A central atrium floods the interior with daylight and aids in orientation. The upper four floors feature clearly structured open waiting areas, along with outdoor spaces that open up to the surrounding greenery. Each floor is divided into sections for refugees and for employees.

Efficient, serially built accommodations open up to the central interior, allowing views in and out through their narrow exteriors. The U-shaped buildings are angled to create versatile spaces despite the uniform architecture by responding to the site, trees, and surroundings in a dynamic way. Communal areas are located on the ground floor, accessible via the spaces between buildings. This urban space widens slightly towards the west, forming green inner areas that serve as private outdoor spaces providing orientation and security. The accommodation area consists of seven 5-story buildings, each housing 20 residential clusters with 5 clusters per floor. The design allows for easy identification and access to individual quarters. Play and recreation areas are located in the semi-private inner courtyards and central inner area, while sports and leisure facilities are situated in the northern outdoor areas.
