Part of the productive ~階建(かいだ)て pattern used to describe the number of stories in a building. The pattern is: number + (かい) + ()て.

COMMON PATTERN EXAMPLES:

  • 二階建(にかいだ)て: two-story
  • 三階建(さんがいだ)て: three-story
  • 五階建(ごかいだ)て: five-story
  • 十階建(じゅっかいだ)て: ten-story

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.

SIMILAR WORDS:

  • 三階(さんがい): third floor — refers to a specific floor rather than the building's total number of stories
  • 平屋(ひらや): single-story house — a specific architectural term rather than a numbered description
