After much war damage had been repaired towards the end of the 1950s and most of the open spaces within the actual city center had disappeared, the question of developing expansion areas for the city arose. As Frankfurt’s city center was oriented more to the west since the mid-19th century with the construction of the western train stations, the two Wilhelminian-style inner-city districts Bahnhofsviertel and the Westend bordered the Neustadt (New Town) and were ideal for further developments. Like the Bahnhofsviertel, the Westend also suffered comparatively little bomb damage. These two districts were also considered to be well developed due to their proximity to the main train station, wide roads and a fast connection to the airport.
The Bahnhofsviertel is a Wilhelminian style district with block development and was also densely built up at the time. The population in this area declined, but the number of jobs rose. The corporate headquarters of Dresdner Bank and Philipp Holzmann were built in the well-developed Bahnhofsviertel. These two companies were the only ones to build high-rise buildings in the station district in the 1960s and 1970s. However, the original high-rise buildings have not been standing for a long time. The Zinserturm of Dresdner Bank was meanwhile replaced by the Gallileo tower and the headquarters of Philipp Holzmann gave way to the Skyper high-rise.
The adjacent Westend district was more interesting for trade, banks and insurance companies than the Bahnhofsviertel, which was already largely used for business purposes. In the 19th century, however, the Westend did not emerge as an inner-city business district, but as a purely residential area for the upper class. Planned for a much smaller city, it was now in the middle of the big city due to the rapid urban development of Frankfurt. Due to the inflationary period, the murder of Frankfurt’s Jews in the Third Reich, the turmoil of the war and post-war and the incipient suburbanization of the bourgeoisie, the original social structure had largely been lost. Around 1960 the Westend was largely a “simple” residential area.
In the Westend at that time there were mainly two to three-story classicist, Wilhelminian and Art Nouveau villas with large gardens. Many of the buildings were largely preserved, but in a poor structural condition. This fact made the Westend on the one hand one of the most beautiful and historically valuable districts of Frankfurt, on the other hand – in view of the central location and the low usage density – in the eyes of urban planning and politics the ideal expansion area for the growing city.
