A multi-story and vertically oriented building, usually used as a residential, office and commercial property, with an overall height of 150 meters or more. In Switzerland, only two buildings currently fulfill this requirement: Roche Tower 1 and 2 with heights of 178 and 205 meters.

Buildings with this type of use and a height of 30 meters or more are considered high-rise buildings according to the Swiss definition of the Association of Cantonal Building Insurers.
