Dymaxion House - Buckminster Fuller Institute
The Dymaxion House was to be leased, or priced like an automobile, to be paid off in five years. All this would be possible now if houses were engineered, mass-produced, and sold like cars. $40,000.00 sounds about right. In 1946, Bucky actually built a later design of the Dymaxion House

Buckminster Fuller's Dymaxion House as a Paradigm for a Space Habitat
FIGURE 2 shows the 1946 Dymaxion House floor plan. The plan divides the 102.2 sq. m (1100 sq. ft.) of floor area approximately in half between the two bedrooms (and their accessory enclosures) at the top and the living room, kitchen and "entry hall" (which leads nowhere) in the lower half.

This was decades before the Fly's Eye dome.
