platform frame
Quick Summary
Platform framing is a method of building construction that uses many small, closely spaced members assembled by nailing. It is the standard for much of U.S. suburban housing.1
In this system, each floor is framed separately. Carpenters first build a floor, which includes wood joists and subflooring. This floor then serves as a platform for fabricating and lifting the stud wall frames for the next level. This contrasts with balloon framing, where studs run the full height of the building. Platform framing offers ease of construction and has seen a revival, particularly after World War II.1
