In which type of building construction does wood run from the bottom to the top?

Balloon frame construction is characterized by the use of long vertical framing members that run continuously from the foundation to the roof. This technique allows for better structural integrity and reduces the number of horizontal members needed, resulting in fewer joints and a more stable frame. The walls in balloon framing are typically built with studs that extend the full height of the building, which is a significant aspect of this type of construction. This method was widely used in the United States during the late 19th century and early 20th century before platform framing became more prevalent.

In contrast, platform framing, which is more common today, involves constructing each floor as a separate platform, with the wall studs terminating at the floor systems. Steel frames utilize steel beams and columns, and pre-fabricated frames involve sections manufactured off-site and assembled on-site. Understanding the distinction is crucial when assessing building types and their structural characteristics in fire safety and construction practices.
