The house is a squat glass pyramid inverted base up that pivots to track the sun. The inverted pyramid top is the most notable technology of the house, but other systems include solar water heating collectors (also in the pyramid base) for domestic hot water and in-floor radiant heating, and an easy-to-move and easy-to-expand home for middle-aged people who want to live outside an urban area.
