Xanadu House. Bob Masters.

The Xanadu Houses were a series of experimental homes, built to showcase examples of 
computers and automation in the home in the United States. The architectural project began in 
1979, and during the early 1980s three houses were built in different parts of the United States: 
one each in Kissimmee, Florida; Wisconsin Dells, Wisconsin; and Gatlinburg, Tennessee. The 
houses included novel construction and design techniques, and became popular tourist 
attractions during the 1980s.

The Xanadu Houses were notable for being built with polyurethane insulation foam rather than 
concrete, for easy, fast, and cost-effective construction. They were ergonomically designed, and 
contained some of the earliest home automation systems. The Kissimmee Xanadu, designed by 
Roy Mason, was the most popular, and at its peak was attracting 1000 visitors every day. The 
Wisconsin Dells and Gatlinburg houses were closed and demolished in the early 1990s; the 
Kissimmee Xanadu House was closed in 1996 and demolished in October 2005.
