6 Interior Construction 6.1 Partitions 6.1.1. Construction. Partitions, unless otherwise specified elsewhere herein or on the design plans, shall be framed of 2"x4" stock with a sole plate and top plate well attached to the slab and ceiling, respectively. Certain partitions, as shown on the design drawings, shall be insulated with unfaced fiberglass batts appropriate for 2x4 studwall thickness; those partitions enclose the entranceway and the utility-service area. 6.1.2. Surface Covering. All interior wall and partition surfaces shall be covered by 1/2-inch or 3/4-inch thickness shiplap or tongue-and-groove board of knotty pine, applied horizontally, matte side out. The boards shall be so cut and applied that vertical seams lie over studs and do not align. In the workroom area, however, the wall area above the workbench shall be covered instead with a 4'x9' sheet of plywood of the same kind used for the external wall sheathing (with pine continuing up from the plywood top with the plywood-pine joint trimmed). 6.1.3. Trim. Corners shall be trimmed by placement of a 1"x1" vertical. A thin low floorboard, suitable for finish by oiling as described in 6.1.4 below, shall be supplied along all walls and partitions. 6.1.4. Finish. All interior wood surfaces, including floors, shall be finished solely by brush application of "OS/Color" brand clear Hardwax Oil. 6.1.5 Open Partitions 6.1.5.1. General. In certain areas, as shown on the design plans, one surface of a partition wall shall be left partially uncovered so as to provide shallow in-wall storage space. 6.1.5.2. Trim. All such openings shall be suitably trimmed at the edges of the exposed area. 6.1.5.3. Stud Selection. The partition studs visible in any such opened area shall be selected to have no material flaws, discolorations, visible stamps, etc. 6.1.5.4. Shelving. In any space so revealed, shelving of better-quality 2x4 stock shall be run between the exposed studs at heights as shown on the design plans. 6.1.5.5. Locations. The opened areas are: in the TV Room, on the west wall; in the bedroom, on the east wall; by the master-bath sink, on the east wall; and by the secondary sink, on the east wall. 6.1.5.6. Finish. Intra-partition shelves and exposed partition stud surfaces shall be finished like normal wall surfaces as described at 6.1.4 above. 6.2 Built-Ins 6.2.1. Material. All built-ins, unless explicitly otherwise specified, may be built of any suitable wood lacking material blemishes. Any plywood used shall have all visible surfaces blemish- and repair-free. The desktops in the office and kitchen areas, however, shall have hardwood surfaces, which may be plywood veneers, of a species and grade selected in consultation with us. 6.2.2. Backs. Unless explicitly specified otherwise, any built-in located against a wall or partition surface may use that wall as its back and need not have an integral backing. 6.2.3. Secural. All built-ins shall be well secured to the walls or partitions, as may be, to avoid pulling out or racking even when fully weighted with such loads as may be reasonably inferred from their manifest purposes. 6.2.4. Designed. Those built-ins of sufficient complexity to have been placed on design drawings are listed below; the drawings describe them more fully. (Items simple enough to only be described are specified at 6.2.5, below).

Area Covered. The area comprising the bathrooms, from the shower stall on the west to the last sink on the east and from the north wall of the house to the south walls of those rooms, shall be built up off the slab to a raised floor.
