on Broadkill Beach, Delaware, United States, and destroyed to make way for a double-wide modular home. Some have been vandalised in drive-by shootings. The oil crisis of 1973 led to an abrupt halt in plastic production. Synthetics became very expensive to produce. Additionally, the public was shifting their view of plastics from a miracle material to an ecological concern. These problems provide context to the discontinuation of the Futuro House. Fewer than 100 were made and it is estimated that today around 60 of the original Futuro Houses survive, owned mostly by private individuals. The prototype (serial number 000) is in the collection of Museum Boijmans Van Beuningen in Rotterdam, The Netherlands. The Futuro no. 001, the only other Futuro currently in a public collection, is in the possession of the WeeGee Exhibition Centre in Espoo, Finland. There are approximately 63 confirmed Futuro Houses in existence across the world. They are in Australia, Denmark, Estonia, Finland, France, Germany, Greece, Japan, The Netherlands, New Zealand, Norway, Ukraine, Russia, Sweden, South Africa, Taiwan, United Kingdom, and the United States of America. Conservation In 2010, Finnish conservator Anna-Maija Kuitunen made a damage assessment plan for the first Futuro ever made (serial number 001). This was done as her final thesis for the Metropolia University of Applied Sciences in Finland ("Futuro no. 001 – documentation and evaluation of preservation need"). The thesis is openly available via the Finnish Theses database and contains a large number of indoor detail photographs and drawings of the Futuro House. A UK artist, Craig Barnes, purchased and restored a Futuro house in 2013 – 14. He had discovered the wreck whilst on holiday in South Africa and had it shipped back to the UK before commencing restoration. The Futuro house—the only one in the UK—was on display to the public as part of an exhibition on the rooftop of Matt's Gallery, London (until December 2014); the house was featured on the fourth series of the Channel 4 programme George Clarke's Amazing Spaces (Ep. 2). The Swedish Air Force Museum is restoring a Futuro house. It will be placed in front of the museum at the new playground during May 2021. One Futuro house was found to be biodegrading due to cyanobacteria and archaea. Marketing and media The Futuro home was primarily marketed towards young adults as an avant-garde retreat. Their promotion emphasized the versatility of the home in different
