The striking T-Center St. Marx was designed and built by architect Günther Domenig. Completed in 2004, the project has 119000 m2 of usable floor space and contains offices for 3000 employees. Unusually proportioned, the building can be described as a reclining structure 60m high and 255m long with a 40m wing cantilevering out. From a town-planning perspective this building represents the first step in the development of a new district on the site of the former St. Marx abattoir and cattle sheds. The T-Center St. Marx is not only an office building for its owner, T-Mobile, it’s also a large sculpture. Architect Domenig wanted to create a 280 meter long horizontal skyscraper and ended up with what is quite possibly the most unique office building in Vienna (text from Princeton Architectural Press and Michael Hierner).
