Although more well-known for his earlier design of the Futuro House, In 1971, Finnish architect Matti Suuronen designed the awesome mod pod that is the Venturo CF-45. The 45 square-meter design was marketed for a number of purposes, including recreational.
The Venturo was extolled as "maintenance free" because it's exterior materials were fiberglass, anodized aluminum and glass. The low-weight, pre-fabricated module allowed for installation without much interference to the surrounding landscape, because heavy earthmoving equipment was not required.
Despite is't great mod design and small-house luxury features (anyone care for a steam?), only 19 Venturo homes were sold, and production was quickly shut-down.
But wait - what about this large collection of Futuros and Venturos, located on the northern coast of Taiwan?
Mystery surrounds the later Taiwanese Venturos, which are located in a mostly-deserted Taiwanese resort park that is thought to have been built around 1979. Who was manufacturing the later Venturo homes? A couple of the homes have residents, and have been maintained.
Sadly, most of them look like this.
A random Venturo sighting, this one was located on the highway between Kyoto and Osaka. The home was reportedly removed by the landowner in 2008, it's current location is unknown (sadly, I suspect it no longer exists).
This restored Venturo is now a cafeteria/information center at the Kivik Art Centre in Sweden.
