The house has to please everyone, contrary to the work of art which does not. The work is a private matter for the artist. The house is not.
The room has to be comfortable; the house has to look habitable.
Be not afraid of being called un-fashionable.
The work of art shows people new directions and thinks of the future. The house thinks of the present.
Supply and demand regulate architectural form.
Architecture arouses sentiments in man. The architect's task therefore, is to make those sentiments more precise.
