640 apartments planned in Berlin: Instone acquires plot on former hospital site in Charlottenburg

Instone Real Estate (“Instone”), a residential developer operating throughout Germany, is planning a new residential quarter on the former site of Schlosspark-Klinik in Berlin-Charlottenburg and has acquired a plot of more than 25,000 sqm for this purpose. A total of around 640 apartments with total residential floor space of approximately 42,500 sqm are to be built. The plan is to create a mix of owner-occupied apartments, privately funded rental apartments, and social housing. The new buildings will be constructed to the EH40-QNG sustainability standard. Two existing buildings will be renovated in accordance with conservation guidelines and converted into residential accommodation. Construction is scheduled to begin in 2028, with completion of the quarter planned for 2033. 

 

The project will be carried out together with the group subsidiary Nyoo Real Estate GmbH (“nyoo”), which specialises in efficient, serially-planned housing concepts. Instone will develop around 370 new-build owner-occupied apartments, as well as a further 24 units as part of the heritage-compliant refurbishment for owner-occupiers and capital investors. nyoo will be responsible for the rental housing component: around 190 privately financed rental apartments and approximately 50 subsidised apartments. 

 

“This presents a rare opportunity to develop a neighbourhood comprising several hundred apartments based on existing planning permission. The plans include generous open spaces and a mix of uses to suit different lifestyles – in a beautiful, established setting right next to Charlottenburg Schlosspark,” says Saidah Bojens, Branch Manager for Berlin and Saxony at Instone Real Estate Development GmbH. “The secure planning framework and the quality of the location make the site particularly attractive to us. The constructive support from the district has facilitated the process from the very beginning.”

The project envisages high-quality, multi-storey architecture with spacious open areas and a high quality of life. Whilst solid building blocks are to be constructed on the western side, the development will open up towards the Schlosspark with several low-rise blocks arranged in a loose pattern. The project is based on an urban development concept agreed with the district, including a share of subsidised housing and contributions to social infrastructure.

 

Hospital operations on the site were discontinued in early 2026. Clearance of the site is due to be completed by the end of June 2026. Two buildings will remain leased to the hospital operator Alexianer St. Gertrauden GmbH until May 2028, after which they will be vacated and handed over.

 

The plot is located on Heubnerweg in the immediate vicinity of Schlosspark Charlottenburg in a predominantly residential environment. In future, a public pathway is to run through the quarter, providing direct access to Schlosspark. Retail amenities, educational facilities and medical care can be found in the immediate surroundings. The location within Berlin’s S-Bahn ring has very good public transport connections. Westend S-Bahn station is within walking distance and provides access to the Ringbahn.
