In Brojects parlance, a main build is a larger, more prominently featured building project. The titles of individual episodes are derived from the name of the main build featured within them. The term is used to differentiate these builds from the side build, a smaller, relatively minor building project featured in the same episode. Oftentimes, the main builds and side builds are related to one another in some form. The term was coined by members of the Season 1 production crew in order to differentiate between the sometimes numerous builds featured in any given episode.
