What type of construction typically features two-story wall studs?

Balloon framing is characterized by the use of continuous wall studs that extend from the foundation to the roof line, typically resulting in two-story wall studs. This method allows for a tall wall system where the floor joists are inserted between the studs, connecting the walls on different levels. The height of these wall studs permits fewer interruptions in the vertical structure, leading to more open spaces inside the building and potentially improving material efficiency.

While platform framing is more commonly used in modern construction and involves shorter, individual wall studs that do not extend beyond one story, it does not feature continuous two-story studs. Timber framing employs heavy timbers and often incorporates different joinery techniques, which also do not align with the concept of the continuous two-story wall studs seen in balloon framing. The option referring to both balloon and platform framing does not apply, as only balloon framing specifically involves this characteristic of wall stud height.
