A building that commits to exactly one roommate, forever, in writing.

means A building divided into two separate living units, or an apartment with two floors connected by an interior staircase.

from From Latin 'duplex' meaning 'twofold' or 'double,' built from 'duo' (two) plus a root related to 'plicare' (to fold) — so literally 'folded twice' or 'two-fold.' The same root gives us 'duplicate' and 'complex,' all carrying that sense of layers or parts folded together.
