The Park Tower (formerly known as the SGZ-Hochhaus) is a skyscraper in the Westend of Frankfurt. It was built in 1972 as the administrative headquarters of the Southwest German Co-operative Bank (since 2001 DZ-Bank). The then 96-metre high building with a black and silver facade was briefly the tallest skyscraper in Frankfurt. It is located in Reuterweg near the Opernplatz.
Between July 2005 and autumn 2007, the building was gutted completely and radically restructured. Since then, the 115 metre high building offers approximately 24,000 square metres of gross floor area.
The slightly oblique to the old opera house standing building was increased to plans by the architect Albert Speer & Partner, at three levels and supplemented with a second block, which lies down like a stone buckle around the shaft of the tower. The new building is bright with natural stone dressed, the old building completely glazed. The main tenant of the building is the internationally active law firm Freshfields Bruckhaus Deringer, which has leased almost the entire building.
The owner of the property is a property company of Dietz AG, Bensheim.
