Loos was attentive to the physiological effects of his space and strove to create spaces that were comforting and responsive the needs of its owner. Rooms were not decorated according to particular style dictated by Loos, because one's tastes evolve and change with time. The interiors of the Villa Muller reflect the personal taste of the Muller family, with rugs, furniture, and artworks that were chosen by the family, rather than the architect. As in "The Poor Little Rich Man," discussed in previous chapters, Loos did not believe that an architect should dictate the furnishings of his homes.
