More than a Building

The mainBuilding is a property that caters for the highest of standards and sets new trends in urban development. Generosity was the fundamental principle and authenticity the yardstick from the overall design through to the smallest of details. 

A comb-shaped building curving into an internal courtyard situated along Guiollettstrasse and Kettenhofweg, which makes maximum use of daylight, forms the framework for the whole development. Individually designed squares and courtyards inside create a sense of calm and provide a space in which to relax. The listed facade facing the Taunusanlage park area has been carefully and harmoniously integrated into the seven-storey new building on Guiollettstrasse. 

The clearly divided facades of the new building, which are clad with high-quality natural stone, rest on solid, natural stone foundations. Generous rows of windows and whole-glass facades allow for optimal light entry. A successful synthesis of historical structures, prestigious architecture, highquality fittings and cutting-edge technology has been created.



The mainBuilding is located in the heart of the financial city of Frankfurt am Main, in a top location directly by the Taunusanlage park area and opposite the Alte Oper, the opera house. It is a fundamental part of the banking district. The pedestrian area and the international business area in Westend are in direct proximity to the mainBuilding. 

Between grand boulevards and beautiful squares and parks, stylish old buildings meet modern architecture and imposing high-rise buildings. However, it is not only the first-rate ambience and famous surroundings that make the Taunusanlage-based mainBuilding an ideal business address. Excellent links to the public transport network, the central train station and the airport as well as to the city’s main traffic arteries ensure that regional, national and international destinations can be reached quickly.
