Union Investment Sells Rund Vier Complex in Vienna to Thalhof Immobilien

Union Investment has reportedly sold the “Rund Vier” office complex in Vienna’s Viertel Zwei district to Thalhof Immobilien.

The OGNI Gold-certified property was held in the portfolio of Union Investment’s open-ended UniImmo: Deutschland real-estate fund. The purchase price was not disclosed.

“After a holding period of around 15 years, during which the office ensemble generated stable income for our fund, we took the opportunity to optimize the portfolio and strategically reduce the office ratio in UniImmo: Deutschland,” explained Alejandro Obermeyer, Head of Investment Management DACH at Union Investment.

The Rund Vier complex, which was designed by Henke Schreieck, consists of four concave-convex office buildings staggered in height with a total rental area of around 25,000 square meters. It is located in the renowned Viertel Zwei, one of Vienna’s most important office clusters.

The transaction was brokered by Zoechling RE. The Schoenherr Law Firm advised Union Investment on the deal, with tax advice provided by TPA. Thalhof received legal advice from the Tiefenthaler Gnesda Law Firm and tax advice from BDO Austria.
