With a gross floor area of approx. 64,000 m² the office building, which is situated entirely on freehold land, is one of the largest buildings in Amsterdam. The building is currently fully leased to Hogeschool van Amsterdam (Amsterdam University of Applied Sciences). Leeuwenburg forms part of the office district known as De Omval. The Leeuwenburg office building is located at Weesperzijde 190 in Amsterdam, at a stone’s throw from the A10 ring road and in the immediate vicinity of Amstel railway station. De Omval is mainly known for the Rembrandt Tower, the Breitner Tower with the Philips head office and the Mondriaan Tower, which is home to companies including Delta Lloyd, Rabobank Amsterdam and CMS. The building dates from the 1970s and was designed by the firm of architects Zanstra, de Clerq Zubli, Lammersma & Partners (currently known as ZZDP Architecten), which later also designed the Rembrandt Tower. In the 1970s the former Rijkspostspaarbank was the first lessee of the Leeuwenburg building.
