The piazza is, however, a new problem, but not a very difficult one after the processes already described. A simple way, suited for rustic structures or rough cabins, is to set the piazza posts in the ground to a depth of two or three feet, sawing the tops off at the height of the piazza roof, and simply nailing a system of floor-timbers for the piazza floor to these posts and the side of the house and flooring it with boards, while the roof of the piazza is supported on the tops of the posts. This is not a good way, however, for a carefully built house.
A strip of joist or plank can be spiked to the side of the house at the proper height, and to this can be nailed a system of floor-timbers for the piazza floor (see page 287), the outer corners and middle resting upon stones or posts in the same way as the rest of the building. This is then floored crossways, the whole having a slight slant outwards to shed the water. Upon this platform are raised the piazza posts, and at the top of these is nailed a roof system, which is covered with boards in the same way as the floor beneath. Enough slant should be given the roof to enable it to shed the water freely.
The other details do not differ from those already described.
Before beginning work read carefully Marking, Rule, Square, Saw, Plane, Nailing, Screws, Hinges, Painting, in [Part V]., and look up any other references.
An excellent form for a small structure is that shown in Fig. 393. This has a hip-roof, which is the only essential difference between it and the types already shown.
