Cooking area (7)
I believe the answer is:
kitchen
'cooking area' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for kitchen that I've seen before include "Where heat's to be stood" , "Site of 4 [GAS OVEN]" , "Room for food" , "Room - thicken (anag)" , "food prepared here" .)
