UNIVERSITY OF CALIFORNIA COLLEGE OF AGRICULTURE AGRICULTURAL EXPERIMENT STATION BERKELEY, CALIFORNIA A TWO-ROOM FAMILY UNIT WITH BATH L. W. NEUBAUER' and H. L. BELTON This plan is one of a series of labor-camp structures prepared to aid fanners in the selec- tion of suitable farm-labor housing during the war emergency, and at the same time to provide a semipermanent farm housing structure. It is simple in design, provides adequate floor space, and is well lighted and ventilated. When proper- ly arranged in a camp group, it presents a neat appearance; moreover, it provides a structure which meets the requirements of the State Labor Housing and Sanitation Act. Restrictions" on Materials Farmers contemplating construction should fa- miliarize themselves with available local materi- als and should consult with county war boards and other Federal agencies to make certain they are conforming with regulations regarding the use of any critical materials involved. In some cases, the use of substitute materials may be necessary. Size and Arrangement The illustrations show a two-room family unit, 16 x 24 feet in size. The combined kitchen and dining room provides adequate floor space and lo- cations for equipment for the preparation and serving of food. The unit living and bed room may be conveni- ently arranged to care for a small family. Toilet facilities as shown may not be advis- able when several units are grouped together for summer housing only. For such a grouping, a cen- tral bathroom and washroom is recommended.

Only dry material should be used for the exterior siding. Under war conditions very little dry lumber, suitable for siding, is avail- able. Green lumber shrinks to such an extent is about 12 inches above 4x4 inch stringers laid istant wood blocks. A tight r laid on 2 x 6 inch joists rs is recommended (see plan g for walls and roof is the studding and rafters rs.

[1] that it may be necessary to remove and re-lay it after one season of exposure. In order to avoid this situation, it is suggested that the exterior wall surfaces be sheathed horizontally with com- mon 1x8 inch stock boards, or a common grade of shiplap. These surfaces may then be covered with a good grade of single-ply roll roofing laid ver- tically, with the joints and corners stripped with battens or lath. The lower grades of lumber are acceptable for this type of sheathing and such shrinkage as occurs may be corrected as far as tightness is concerned by subsequently surfac- ing the walls directly over the roll roofing. It is reasonable to assume that dry lumber of the pattern desired will be more readily available at a later date. The thinner less expensive types of siding not generally placed directly on the studded walls are suitable when applied over a tight -sheathed wall of this type. Roofing The roof surface should be tight-sheathed, and then may be covered with roofing paper, as is done with the walls. If possible, however, a more permanent type of roofing material such as wood or composition shingles, galvanized iron sheets, or a heavy grade of roll roofing, should be ap- plied. Windows, Doors, and Screens The windows are of the four-light, single- sash type, and are 2 feet 6 inches by 3 feet in size, except for toilet and shower windows, which are 2x2 feet. A drop-in sash supported by wood shields, and a sliding type, are shown (see plan details A and B) . Sash hinged at the bottom to open inward (supported by a chain) , or ordinary double-hung windows may also be used. Screens should be installed on all windows. Standard full-panel or panel-and-glass doors may be in- stalled for the exterior openings. Panel doors are recommended for the interior openings. All, however, may be home-built. The screen doors may be of the full-screen, or the screen-and-panel type. Closets and Shelves Clothes closets of the curtain-front type may be located as desired. For the kitchen, 1 x 12 inch shelving is recommended, located as shown. Spacing of 12 inches is usually most convenient, with the top at door height. Shelves beneath the sink and drains may be installed as desired. Interior Wall Surfaces No finish for the wall interiors is suggested at this time, other than for the partition wall separating the kitchen and bedroom. For this wall, the kitchen side may be sheathed to the rafters, using 1x8 inch shiplap laid horizontally. If a more finished structure is desired for post-war occupancy, the wall interiors may be sheathed with tongue-and-groove lumber, plain boards and battens, UN1V r fi : FORNIA COLLEGE OF . ..'"JCULTURE DAVIS Head Jamb Sill Door Jamb door Head Jamb Sil Detail A Frame Construction with Drop-in Sash Window height same as door -tr^-r H 1 - "'=!ilMlli j Grade % Detail B Concrete Floor Slab and Sliding Sash 4 Concrete 4 ■ or A 1/S/IISI^ or ■ ■ ■ W=///-' =111: tr wood Grade studs 24;ac| _Plate & Rafter Connection Detail C Curbed Concrete Floor Slab THIS PLAN CONFORMS WITH LABOR CODS STATUTES I937,CHAP90, PGI8S.

The water closet, shower head, and fix- tures should be of simple standard design. Water supply and sewage disposal lines outside the house are not estimated. For sewage disposal, see Extension Circular 82, A Septic Tank for Farm Homes , free upon request to the Agricultural Ex- tension Service, University of California, Berkeley, California. Painting Two coats of a good grade of lead-and-oil paint are recommended for all exterior woodwork. When walls are finished with roofing paper and battens, only the trim requires paint. If rustic or other wood exterior finish is used, it may all be protected with paint.

Alternate Construction Where good drainage is obtainable a concrete floor may be desired. It provides a satisfactory floor for a family unit; it is easy to clean and keep in good condition. A 4-inch slab of 1- 2 1— 4 mix, with additional thickness at the outside edges for a footing and a gravel fill beneath the slab to secure the proper elevation of the floor above grade, is recommended (plan detail B) . The concrete should be well tamped into place, and the surface edged true and given a smooth finish. Curing for several days with a bed of wet sand or straw is advisable. A curbed concrete slab which permits hosing off the floor and affords protection to the lower woodwork is shown in plan detail C. If a concrete slab is desired, deduct the fol- lowing from the materials list: items 1 to 5 in- clusive; 8 pounds 8d common nails; and 3 pounds 20d common nails. Then add: 30 sacks Portland cement 4 cu. yds. sand 4g cu. yds. gravel (fill not estimated) 16 only, g"x 7" carriage bolts If rustic siding is desired, deduct items 6, 7, 8, and 12 from the materials list, and add: 1,220 bd. ft. of 1" stock rustic 3 gal. paint 5 gal. linseed oil 1 qt . turpentine If roll roofing is desired, deduct items 9, 10, and 11 from the materials list and add: 6 rolls 3-ply roofing paper Summary If alternate construction is used, the critical materials listed as additions to, or deductions from, the original list should be corrected in the rough summary of materials.
