A competent architect should be capable not only of producing an artistic and pleasing exterior design suitable for its particular site but he should be able also to develop a convenient, attractive, and straightforward house plan. It is obvious that the plan governs to a large extent the exterior design and the particular architectural style. Too often the prospective home-owner makes the mistake of visualizing the house plan and the exterior design as unrelated while in reality they should be developed together and each should express the other.1 After the site is selected the plan doubtless should be the next consideration, and it should be developed with the exterior design in mind. The first consideration in developing the plan is obviously the amount of money to be spent. The following then should be considered: (1) Size and make-up of the family; (2) activities to be carried on in the household; (3) needs and desires of individual members; (4) the site on which the house is to be built; (5) beauty and attractiveness in development; (6) placement of furniture.

Some progress has been made in house-planning, particularly in the planning of small and inexpensive homes. Scientific investigations and experiments on ventilation and the value of sunlight, time studies and fatigue studies of household operations, and a better knowledge of the requirements of individuals have raised the standards of houses. Many are now being planned with consideration for cross ventilation in bedrooms and kitchen, good circulation of air throughout, sunlight in every room whenever possible, convenient arrangement of rooms, and wall and floor finishes and built-in equipment that will eliminate all possible labor. Consideration also is given to rooms that are pleasing in proportion and with a desirable outlook.

1 In some of the new planning experiments the exterior design has been made subservient to comfort and convenience and the house has been built around the plan. Such a project exhibited in Paris is described in the following paragraphs:

"What probably will be the most curious street in Paris for many years to come was opened recently by the French Minister of Commerce, the Prefect of the Seine and the Prefect of Police.

"The street consists entirely of houses built on the most approved principles of hygiene and in the plans which recall some ultra-modern exposition of decorative art rather than the staid, uniform apartment houses of Paris.

"Situated in a district of Auteuil, which has retained its century-old trees and still boasts of many open spaces, the new. street has been named rue Mallet-Stevens, after the distinguished French architect who designed this experiment in house construction.

"Seen from the outside the buildings present an entirely different aspect from those in the surrounding streets. Balconies, windows in rows and sloping roofs have disappeared. Stories are undefined, some being higher or lower than the adjoining ones.
