Two methods are used in standard wood house or “stick” framing-balloon or platform-and both have advantages and disadvantages. Balloon framing is sometimes used with two-story buildings. In balloon framing the studs extend as one, from the sill to the top plate of the second story. The second story floor joists are supported by a ribbon board set into he studs. This type of construction is the most difficult, but does provide unobstructed openings between the floors allowing for easy installation of utilities without nothing and cutting openings. Fire stops must, however be installed at the second story floor level between the studs.
Platform framing can be used for either simple or two-story and is the easier and most common method of construction. Fire stops are automatically created with this type of construction. Construction a single story is the easier, a two-story or split level is harder.
Platform framing is easier than balloon framing because you can construct and erect the second story walls on the second story floors.
Either construction can be done on a concrete slab or on a foundation. The slab acts as a floor, a foundation requires a floor to first be constructed. Then the walls are framed on the floor (or slab) and raised in place.
