After World War I there were plans for the construction of high-rise office buildings in various German cities, following the examples in the United States. Such tall buildings were called Turmhäuser in Germany at the time (tower houses).
In Frankfurt, such a building was to be built on the property between Moltkeallee, Bismarckallee and Königstrasse (today Hamburger Allee, Theodor-Heuss-Allee and Emil-Sulzbach-Strasse). The men’s clothing factory Fritz Vogel und Co. planned to build a new business building there. Part of the building complex, planned by architect Fritz Voggenberger, was to be an approximately 60-meter-high office tower with 17 floors.
Anticipating the requirements of today’s high-rise buildings, publicly accessible uses were planned for the plinth area. There should have been a telegraph station and public phone booths; an industrial exhibition was planned for the adjacent atrium.
The city council took a positive view of the project, the building inspector had no reservations and the Frankfurter Zeitung also accompanied the project with benevolence and extensive reporting.

However, the neighbors raised an objection, so that in the spring of 1923 a settlement was concluded that the tower should not be constructed. As a result, only a first component of the complex was realized and put into operation.
The existing parts of the business building were demolished in the 1960s. Later, the property was supposed to become a high-rise location. The Poseidon high-rise was completed in 1986 and has been called LEO since it was renovated in 2013.
The actually built first high-rise in Frankfurt was the 33-meter-high Mouson Tower (Mousonturm), completed in 1926. The I.G. Farben Building (I.G. Farben-Haus) and the Union House (Gewerkschaftshaus) followed a few years later. But only after World War II taller buildings were developed in Frankfurt.
