Design & Art

What would the niu be without design and art? Well, it surely wouldn’t be the niu, because we have chosen art as a central design element. Each design of our houses stands for its own story, inspired by the neighborhood, culture and history of the city. For the art design, we turn to emerging, young artists* who find a platform for their creativity with us. With great, individual pictures and murals they show what "street art" can be and bring our motto to life with humor and attention to details.

Opposites attract

The niu Square will take you on a sumptuous time travel. Our concept and design mirror the baroque ambience of a historical but simultaneously innovative city. At the niu Square you can hold court and enjoy your time away from appointments. You’ll be surprised.
