This is the first-hand account of a young couple who in 1936 challenged Wright to produce a decent house for $5,000. Wright responded with the innovations--floor heating, flat roof, concrete floor, solid walls, grouping of utilities, carport, seclusion from the street but openness to a garden through banks of door windows--that made their house the revolutionary "Usonia Number One."
Within five years the Jacobs moved to the country, where Wright designed the "Solar Hemicycle," which featured a windfoil design and the passive solar construction that became the prototype for such buildings. The 89 illustrations show the construction and important details of both houses.
