What framing technique was common prior to the introduction of platform framing in the 20th century?

Balloon framing was indeed a widely used construction method before the adoption of platform framing in the early 20th century. This technique involves the use of long, continuous vertical wall studs that extend from the foundation all the way to the roof. It creates a framework where the walls are constructed before the floors, allowing for quick assembly and efficient use of lumber.

One of the main advantages of balloon framing is its ability to create taller structures more easily, as the long studs provide an unobstructed vertical space. However, this technique can also raise fire safety concerns, as the continuous vertical space creates potential passageways for fire to spread up the walls of a building.

In contrast, platform framing, which became predominant in the 20th century, involves constructing one floor at a time with separate, distinct wall frames for each level. This method adds a level of fire safety, as each floor acts as a barrier to the upward spread of fire. The move to platform framing also improved construction techniques overall, leading to better insulation properties and the ability to integrate modern building materials more effectively.

The other techniques mentioned—post and beam framing and timber framing—were also popular historical methods but did not have the same widespread application in multifamily structures prior to the introduction of
