All dimensions of this house are multiples of 3-1/2 feet. Wall, door, and window sections might be prefabricated so that erection would consist merely of bolting the sections together, or the house can be built in the ordinary way. The sketch at the top of page 41 illustrates the use of sheet metal as an exterior covering, the one in the center shows concrete blocks, and the bottom view shows the walls covered with a combination of lap siding and shingles or wide boards. The flat roof should be covered with good roofing and well-insulated for comfort in both summer and winter as described in the working drawings. The cost of the insulated flat roof should not be greater than that of an ordinary pitched roof without insulation. The accumulation of snow will help to keep the building warm.

This is a new type of low-cost house designed to provide five small single bedrooms or sleeping compartments and one bedroom of average size. The sleeping compartments are not very large, but to secure privacy and yet maintain economy of construction, something must be sacrificed. In this case it is unnecessary space. [Illustration: VIEW OF COMPLETED HOME AND FLOOR PLAN] The sketch showing the arrangement of bunks illustrates an interesting feature of this house. In the right-hand room the bunk is near the floor, and wardrobe and dresser space is obtained in the partition between the two rooms. In the left-hand room the bunk is 4 feet above the floor and projects over the one on the other side of the partition. Wardrobe space is arranged under the bunk. This room is especially suitable for a boy. A folding study table is provided under the window in each room. On warm nights air circulation would be obtained by opening the bedroom doors to the hall, which is ventilated by the windows above the lower roof. By omitting all but one of the partitions forming the five small bedrooms two good-sized rooms can be obtained. [Illustration: CROSS SECTION OF BEDROOMS AND WARDROBE AT B-B] [Illustration: SIDE VIEW OF BUNK AT A-A] The exterior appearance may seem, at first glance, unusually severe, but by omitting a pitched roof and the ornamental features of cornice moldings and trim decorations, the cost of construction is materially lowered. Here everything has been reduced to the simplest form possible.
