Gatekeeper's cottage (5)
I believe the answer is:
lodge
'gatekeeper's cottage' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lodge that I've seen before include "Provide accommodation for" , "Deposit as to bank account" , "Masonic association" , "small house alongside park" , "Stay temporarily, with bed and board" .)
