🏠 房 = house/room + 子 = noun suffix; literally 'house-thing'
房 (fáng) on its own means room or house; 子 (zi) is a common neutral-tone suffix that turns single characters into everyday nouns, like in 桌子 (table) or 椅子 (chair).
子 — pictograph of a baby/child with arms out
子 began as a pictograph of a swaddled infant with a large head and outstretched arms, originally meaning 'baby' or 'child.' From there it broadened to 'son,' 'offspring,' and a respectful suffix for masters like 孔子 (Confucius). It also became one of the twelve earthly branches.
