Due to the oil crisis the construction of the skyscraper got stuck in 1975.
Until 1979 no investor had been found to finish the building because of high construction costs and a lack of prospective tenants for the office space.
Later the ECE project development company stepped in and reached an agreement with owners and artisans, and developed a construction program for completion and technical improvement as well as a rental concept.
In 1981 the tower was finally finished and comprised approximately 52,000 m² (560,000 sq ft) of gross floor area.
As of end of  April 2007 approximately 17,000 m² (180,000 sq ft) of office space on the lower 20 floors were not let.
Thus, the occupancy rate was approximately 65 percent.

The building was owned by DEGI, an open property fund of Dresdner Bank from 1985 to 2007 and then sold to the Goldman Sachs Whitehall Fund.
In 2016 it was acquired by PBM Germany, a construction company from Berlin.
