Hamburg | Vienna, 30/09/2025 | Next step in the Austrian residential market: Quantum Immobilien KVG has acquired a high-quality residential property in Vienna for a separate account it manages. The seller is WALTER REAL ESTATE GmbH. Completed in 2018, the property represents modern and urban living in a prime location in the 5th district.
“With this acquisition in the attractive investment location of Vienna, we have succeeded in strengthening the existing fund portfolio,” says Martin Berghoff, Managing Director of Quantum, adding: “Vienna convinces as Austria’s economic center and ranks among Europe’s top metropolises. As a modern, cosmopolitan, and diverse city, Vienna is a hotspot for startups and young people. Looking ahead, demand for high-quality, compact, and centrally located residential space will continue to rise.”
“The sale of this property marks a deliberate step in the strategic development of WALTER REAL ESTATE,” explains Stefan Wierzbinski, Managing Director of WALTER REAL ESTATE. “In addition to our established roles as property holders and project developers, targeted sales from our portfolio will increasingly come into focus in the future—whenever they make economic and strategic sense. This creates new opportunities for investments in high-quality residential and commercial projects.”
Modern and Urban Living in Vienna
The property is located in a central, highly desirable residential area on Sankt-Johann-Gasse and, in addition to 77 apartments, also includes 50 parking spaces in the building’s own garage. The apartment sizes range from two to four rooms, with a focus on two- and three-room apartments, matching the housing demand in Vienna. All units feature a terrace, balcony, or loggia.
The transaction was structured as a share deal. The parties have agreed not to disclose the purchase price. Engel & Völkers Vienna acted as broker for the seller. The buyer was advised by the law firm CMS Reich-Rohrwig Hainz (legal) and MES Real Estate Services GmbH (technical).
Since its founding in 1999, the independent Quantum Immobilien AG has stood for forward-looking project development, attractive institutional investment products and holistic management of real estate investments.
The development business realises its own projects as well as joint venture or service developments. The main focus is on the office, retail and residential asset classes. In addition to new developments, special attention is paid to inner-city redevelopments. To date, real estate projects with a total value of approx. € 6.0 billion have been completed.
