Unless the house is unusually large, a rise less than % of the span (S) leaves attic space which will offer an impractical minimum of headroom. This is not to imply that all floor space in an attic room will require standing or even sitting headroom. The sloping walls near the eaves can well accommodate baggage storage space, closets, or builtin bunks, desks, chests of drawers and bookcases. In addition, dormer windows provide valuable headroom, with space for window seats, vanity tables, sewing machines, easels, or other paraphernalia. Layout. When the attic is small or only one room is to be finished off, the problem is relatively simple. It generally hinges upon how much storage space is to remain unfinished in relation to the stairway's location. Where space exists for an apartment of two or more rooms, preliminary measurements of the available area should be reduced to a rough floor plan, to visualize just how the location of the stairway will exercise an important influence on the arrangement of the rooms. In large houses the attic stairs are often centrally located, providing an ideal situation for a layout with rooms opening from a small central hall. Where the stairway enters the attic at one end, however, there is seldom sufficient headroom available for a lateral hallway, and the floor plan must permit entry into a living or general purpose room first, with the bedroom at the rear. The floor plans of two converted attics are shown in Figure 9.61. Attic Windows. To provide light for the remodeled attic, it may be necessary to build more windows. Windows in gable ends are framed the same as windows in other flat walls (see under window installation earlier in this chapter), but dormer windows present special framing problems. Furthermore, some of the work must necessarily be done outside on the roof of the house. Details of typical dormer framing for the three chief types of dormers (Figure 9.62) are shown in Figures 9.63, 9.64, and 9.65.

The first step in building the walls of the attic room is to draw lines to mark the positions of the plates which will form the bases of the partitions. Underneath the sloping roof the lines should be drawn so as to mark the positions of walls 4 ft. or higher (Figure 9.60). The 2X4 plate is preferably fastened to the floor with lag screws as in Figure 9.67. Before it is fastened, the Courtesy U. s. Gypsum Remodel Research House Fig.
