Until the end of the 1800s, interior walls/partitions in residential buildings are predominantly constructed of brick-lined timber frames.
In transverse walls, beams in the storey partitions form the top and bottom wall plates in the timber frame.
Transverse timber-framed walls are partly load-bearing by virtue of the beams included in the wall structure.
