Hochhaus Uptown München (English: Munich Uptown Building) is a 146 m (479 ft) skyscraper in the Moosach district of Munich, Germany. The 38-storey tower is the tallest skyscraper in the city. The building's glass facade wraps the structure of the building like a tensioned membrane. Circular ventilation elements in the form of individually opening windows enable natural ventilation and provide a reference to the outside world by making the background noise noticeable even on the upper floors. The tower with 50,200 m2 (540,000 sq ft) is flanked by four seven-storey buildings (approximately 8,525 m2 (91,760 sq ft) each) referred to as "campus" which are connected by a transparent roof. A fifth building houses 139 apartments.
