The conditions of comfort for representatives of all psychotypes and subtypes are determined. They can be extended to the main estates of modern society. The same conditions are fundamental in determining the goals of designing a dwelling, including its relationship with the environment, style, functionality, transformability, and controllability, space-planning solutions, color solutions, selection of materials and equipment, and subject content. Peaceful relations in the family, in society, with the environment, are an essential condition for comfort. Possible conflicts and the opportunities to resolve them by using the dwelling are given and classified. Rational spending of money to get the most comfortable dwelling is a very essential component of our comfort/discomfort! And the solution to these problems, based on the theory of self-organization, is also given in this chapter.
