築(ちく)

ちく

prefix

(building) age; years since construction

1. (building) age; years since construction

Used before a number of years to express how long ago a building was built. Almost exclusively seen in real estate listings: 築(ちく)10年(ねん) = "built 10 years ago."

このアパートは築(ちく)10年(ねん)だ。

This apartment is 10 years old.

築(ちく)浅(あさ)の物件(ぶっけん)を探(さが)している。

I'm looking for a recently-built property.

築(ちく)50年(ねん)の古民家(こみんか)をリノベーションして住(す)んでいる。

We renovated a 50-year-old traditional house and now live in it.

Derived from the verb 築(きず)く (to build, to construct), but read ちく in this prefix usage. Appears in real estate listings and casual descriptions of a building's age. The fixed pattern is 築(ちく) + number + 年(ねん).

Common patterns

築(ちく)〜年(ねん): built ~ years ago
築(ちく)浅(あさ): recently built (literally "newly built")
築(ちく)古(ふる): old building (less common but used in listings)
築(ちく)年数(ねんすう): years since construction (the count itself)

Similar words

新築(しんちく): newly built — a building that has never been occupied
中古(ちゅうこ): secondhand, used — for a previously-occupied property
古民家(こみんか): traditional old house — typically 50+ years old, often with historic value
