When are 부엌 and 주방 used?

주방 is more common these days when referring to an apartment kitchen or a restaurant kitchen. Korean textbooks I used starting out (such as this one and this one) translated kitchen as 부엌, possibly to encourage the native Korean word’s use over its Sino-Korean synonym 주방. But 주방 is more common, except in the case of a traditional-style Korean 주택 where the kitchen is separated from the main living space.
