Usage

This compound functions as a noun that modifies other nouns with の, or is used as a prenominal modifier with の omitted. In real estate listings and architecture, this is one of the most basic building specifications. Note that 三階(さんがい) uses the reading がい (not かい) due to sequential voicing (rendaku) after さん.
