Small wooden shelter or house (5)
I believe the answer is:
cabin
I believe this clue is a double definition.
'small wooden shelter' is the first definition.
(I've seen this before)
'house' is the second definition.
(I know that cabin is a type of house)
(Other definitions for cabin that I've seen before include "One's own room aboard" , "Chalet" , "Wooden shack" , "Marine digs" , "Private room aboard" .)
