Swiss Prime Site was founded in 1999. By the year 2017, the Company grew to become the largest stock exchange-listed real estate firm in Switzerland, with a real estate portfolio currently valued at CHF 10.6 billion.
By means of acquisitions, property developments and conversions as well as sharp focus on prime locations, Swiss Prime Site has continuously built up its portfolio. The acquisition of Maag Holding with the Maag site in Zurich-West in 2004 count among the most significant takeovers. Prime Tower and the surrounding annex buildings were subsequently developed at the site. The acquisition of the Jelmoli portfolio of properties in 2009 doubled the value of the Company’s real estate holdings. Since that time, Swiss Prime Site has carried out key strategic acquisitions with Wincasa (2012) and Tertianum (2013). In addition, Swiss Prime Site has generated additional growth and value as well as created premium properties through significant self-development projects – such as SkyKey Zurich (2014) and EspacePost Berne (2015) – or conversions of former office floor space (for example, Motel One Basel and Zurich).
