The Art of Reading Buildings Practice Test

Platform construction uses each floor as its own complete unit built on a separate platform, then stacked to form the next level. This means the floor framing and walls for a given level are assembled independently, creating clear horizontal fire separations and a straightforward, level-by-level framing process. It contrasts with other methods where framing members run continuously through multiple floors (balloon framing), or rely on large vertical posts and beams (post-and-beam) or traditional large timber joinery (timber frame). The description you have matches platform construction, where each floor is effectively a separate platform.
