Sonar Real Estate has acquired the ‘Australhaus’ property in Hamburg on behalf of a special fund managed for a German institutional investor. Sonar acted as investment and asset manager for the vehicle, which is administered by Institutional Investment Partners.
The listed five-storey building was completed in 1906 and modernised in 2015. It offers a total rental area of approximately 1,600 sq m, of which around 60% is used for office and medical practice space. The remaining area comprises retail and storage space. Current tenants include the Italian fashion brand Boggi Milano on the ground floor and a dental practice. Existing vacancy totals roughly 600 sq m of office or practice space and about 150 sq m of retail space.
Australhaus is located on Poststraße in Hamburg’s city centre, within the arcade district between Gänsemarkt and Rathausmarkt. The property benefits from access to the city’s public transport network via the nearby Jungfernstieg and Gänsemarkt stations.
According to Matthias Gerloff, Managing Partner at Sonar Real Estate responsible for German institutional business, the acquisition aligns with a long-term investment strategy and offers scope for income and value enhancement through active asset management.
Legal advice for the transaction was provided by Jebens Mensching PartG mbB, while technical and environmental due diligence was carried out by TA Europe. CBRE acted as broker, and JLL provided commercial advice to the buyer.
