COLONIUS - URBAN DWELLINGS
IN THE GREEN RING
Master Thesis, winter term 2019/20

The project issues the planning of a new sustainable district in the urban center of Cologne.
The urban vision provides densification in form of a sculptural high-rise ring along the concentric urban park, the so-called Green Ring. Thus, the towers become a new part of the concentric city morphology. Higher buildings are placed along the roads so that the city gets again a visible contour. The concept is radically dense and high: a maximum use of space and minimum sealing is aimed to free enough space for the urban park.
The architectural vision envisages a 150m wooden hybrid high-rise residential tower. The building includes public facilities like artist studios, offices, gyms and shops. The apartments, privately financed and cooperative, are located above the treetops to provide a view over the city. The greening of the outer facades on the residential floors is a crucial part of the architecture. The essential building material is timber, a renewable, CO2-neutral and regional building material with a high prefabrication rate and high rationalization in the construction process. In order to fulfill structural requirements and fire protection, concrete used where necessary.
ST. MARY‘S HOSPITAL DÜSSELDORF
winter term 2018/19

The project issues the construction of a new ward block for the St. Mary‘s Hospital in Düsseldorf.
The typology of a high-rise building is chosen in order to formulate a landmark for this public building and to integrate in the city‘s high-rise landscape. Furthermore a new public place, that welcoms all neighbors, is planned in front of the hospital‘s entrance.
Research about different architectonic hospital typologies, including investigations on architectural psycological factors that promote the healing of the patients, were included in the design. The hospital‘s garden is renewed to form a green oasis in the city‘s center. In close cooperation with a student of civil engineering, and a student of Real Estate and Construction Management, the architectonic design, the structural design and the technical building services were planned.
