Hard to put one's finger on it. It is using the verb "build" as a
noun in an untraditional way. Building is the noun derived from to

The OED's oldest example of "build" as a noun (= "a building") is
attributed to 1387. It shows it as obsolete but changes in English
usage are often "back to the future"
