4(b). Structural model: a wood-frame corner at 1:8

Note. A CORNER, NOT A BUILDING, BUT AT THE LARGEST SCALE HERE. One and a half inches to the foot means a full-height wall stud comes out about a foot long, so although the extent is small the parts are large and the joints are visible. The requirement wants a structural layout first, naming the parts of the floor and wall frames, and then the physical model built from it in cardboard, foam board or wood. Naming intermediate girder, joist, bridging, subfloor, sill, sole plate, stud and rafter is part of the work rather than a preamble to it.
