Parapet Walls:
Add to one or more walls. Differ from mansards and facades because parapet walls have no projection. The wall panels below the roofline continue past the eave line to a given elevation. Parapet walls are the economic answer to hiding the gable or rake end of a building.

Transverse Partitions:
A transverse partition runs parallel to the endwall, across the width of the building. They can be used to separate the interior space of a building or serve as an exterior wall when open bays are needed.

Longitudinal partitions serve the same purpose but run the
length of the building.
