Landscape architect Ronald Rietveld talks about Vacant NL. The installation challenges the Dutch government to use the enormous potential of inspiring, unused buildings from the 17th, 18th, 19th, 20th and 21st century for creative entrepreneurship and innovation. The Dutch government wants to be in the top 5 of world knowledge economies by the end of 2020. Vacant NL takes this political ambition seriously and leverages vacancy to stimulate innovation within the creative knowledge economy. Vacant NL is the Dutch submission for theVenice Architecture Biennale 2010. It is made by Rietveld Landscape, which Ronald Rietveld founded after winning the Prix de Rome in Architecture 2006. In 2003 he graduated with honors from the Amsterdam Academy of Architecture.
