After an introduction about the modern "democratic" way of life, Nicolaï-Chaillet discusses different ways of living using a number of floor plans and interior photographs. Among other things, she writes about the border areas between kitchen and dining area and between dining area and sitting area, which actually call for a folding wall. Some flexibility in the home can also be achieved by using individual cabinets to create certain partitions. In addition to family homes, she also discusses two bachelor homes with, respectively, a "male" kitchen cabinet' and a "female" kitchen niche. In general, she emphasizes the best use of space with the most efficient furniture possible. The floor plans and interior photographs nowhere list Nicolaï-Chaillet as the designer.
