The west attic is upstairs above the rooms on the west side of the building. The stairs to the west attic are in the main classroom, and are steep & difficult to climb. It is off-limits to non-members… and members need to have a pretty good reason for going up there: the floors are uneven, the roof is not a constant height, and there aren't very good lights up there.
It's not considered usable space by the fire-marshal, so it is used for administrative storage by the Officers & Board of Directors. By agreement with the Board of Directors, MakerFaire also stores materials in the west attic.
