Berlin's Iconic Karstadt Building Reborn as 'Kalle Neukölln' Workspace Hub

A 1970s department store on Berlin-Neukölln's Karl-Marx-Straße is being transformed into a modern workspace and community hub. Named 'Kalle Neukölln', the project will repurpose the former Karstadt building with a €200 million investment from Maruhn Real Estate Investments GmbH (MREI). The revamped site is set to open in mid-April 2024 after extensive renovations.

The building will span 50,000 square meters of gross floor area, with 40,000 square meters of usable space. Five floors will provide 26,000 square meters of office space, designed for around 4,000 workers across different industries. Nearly 60% of this space has already been leased.

The ground floor will host a 6,000-square-meter food market alongside a 500-square-meter winter garden. Below, 4,000 square meters of retail space will include an EDEKA supermarket. At the top, a 4,000-square-meter rooftop area will feature a swimming pool, dining facilities, and room for up to 1,500 visitors.

The redesign focuses on creating a comfortable, flexible environment for both work and leisure. MREI's investment reflects a broader effort to revitalise the area while preserving the building's original structure.

The project will bring new office space, retail, and public amenities to Neukölln. With most of the offices pre-leased, the site is expected to attract a mix of businesses and visitors. The opening in April 2024 will mark the completion of one of Berlin's largest adaptive reuse projects in recent years.
