The floor areas of the cellar, the porches, and the house itself (the superstructure) are shown with each plan. They do not include unexcavated cellar space nor unfinished space in attics. The areas were figured from the working drawings (see p. 7) because in some cases the dimensions given in the plans herein are approximate only. The superstructure area of a house of more than one story is given here as the area of the first-floor plus the usable area of the second-floor. Stairways, halls, and closets are included. To estimate very roughly what a house might cost, multiply the number of square feet of cellar floor space by a cost per square foot based on the costs stated above. Do the same for the house superstructure and the porches, and add the figures together. This, with allowance for price changes since the spring of 1934, will give a rough estimate of total cost of the house. The actual cost will, of course, be affected by the materials and home equipment which the owner selects and by the skill and efficiency of the builders. If the owner can furnish part of the material or labor, or if interior finish or equipment is omitted, the initial cash outlay may be reduced. Estimates based on local prices and wage rates are to be preferred to those based on the cost figures given above. Little study has been given to what amounts farm people are justified in spending for their houses, but several investigations have been made of expenditures for housing by people with fixed incomes. It is generally agreed that the house ordinarily should not cost more than two and one-half times the average annual net income of the family. In the case of the farm family the value of the living furnished by the farm should be considered as part of the income. Another generally accepted rule, which perhaps is more nearly applicable to farm conditions, is that not more than 25 percent--usually not more than 20 percent--of the average annual net income of the family should be required for housing, including principal payments, interest, taxes, insurance, repairs, and miscellaneous costs. WORKING DRAWINGS Working drawings have been prepared giving all necessary dimensions and details for building these homes. Farmers may obtain copies of these drawings from the agricultural extension services of the State agricultural colleges. The State extension services will supply only those plans which are suitable in their respective States, and usually will make a small charge to cover printing and mailing. CAUTION REGARDING CHANGES
