The framing method described as 'wall framing being constructed one floor at a time' is known as what?

• A. Platform
• B. Balloon
• C. Post-and-beam
• D. Timber frame

Answer: (A)

Platform framing is built by constructing each floor as a separate, horizontal platform. Wall framing for a given story is raised on that platform, and then the next floor is added above it. This means the wall studs run only the height of one story before the next floor is installed, which matches constructing one floor at a time. It’s the standard method in modern residential construction because it makes it easier to run wiring, plumbing, and install sheathing between floors. Balloon framing, by contrast, uses studs that run continuously from the foundation to the roof, not limited to a single floor. Post-and-beam and timber-frame styles use large timber members and different joinery rather than the light-frame platform approach.
