Room to get taxi home (5)
I believe the answer is:
cabin
'room' is the definition.
(cabin is a kind of room)
'get taxi home' is the wordplay.
'get' says to put letters next to each other.
'taxi' becomes 'cab' ('cab' can be a synonym of 'taxi').
'home' becomes 'in' ('he's home' can mean 'he's in').
'cab' next to 'in' is 'CABIN'.
'to' acts as a link.
(Other definitions for cabin that I've seen before include "Building" , "Shipboard room" , "modest accommodation" , "Wooden shack" , "Wooden hut" .)
