Object description
The Karl-Marx-Straße 101 property in Berlin-Neukölln, known as “Kalle Neukölln”, is an impressively revitalized former department store whose history dates back to 1970. Originally, the six-story building served as a Quelle and SinnLeffers department store and shaped the Neukölln cityscape for decades. After various reuses and a long period of vacancy, the property was fundamentally redesigned and modernized from 2018 to 2024 by the renowned architecture firm Max Dudler. The development was carried out for MREI GmbH and K101 GmbH & Co. KG. As part of the revitalization, around 28,000 m² of multifunctional office and commercial space were created, including spacious event areas, an urban garden on the roof, an international food market and exclusive retreats. The distinctive building offers bright, flexibly separable office space, a high-quality façade and numerous common areas that create a modern working environment.
In this outstanding property, coworking provider Kiez Büro has opened its largest location to date, setting a milestone across Germany. Kiez Büro's offer comprises around 2,700m² spread over several floors in the building, spread over 40 individually usable rooms. The core is a feel-good atmosphere with a lounge area, a shared kitchen, library and a variety of retreats.
