The design proposal frames the sides of the rail station with an all-around façade that offers an innovative use of space by making the best of the site’s circulation and natural resources. The intervention will feature rooftop landscaping with local flowers and greenery, rainwater collection, protection from rain, wind, and sunlight, and a visual emphasis on the station’s points of access.

The existing structure at the Platz will be extended and transformed into an arcade that features rooftop greenery. The subway entrance at the station is already topped with a triangular pavilion, so the newly-proposed design will follow through with the same design language, to create a visually-unified facade. In addition to its visual characteristics, the intervention protects travelers from the weather and provides shade for the restaurants and bars.

Due to its special architecture, this design sets quite new urban accents: it’s climate friendly, inviting, and open -just like our city itself. — Reker, Cologne Mayor
