Venturo House, Matti Suuronen, 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.
