Sculpted Rodins, including 'Duck Under a Roof' (7)
I believe the answer is:
indoors
'under a roof' is the definition.
(I've seen this before)
'sculpted rodins including duck' is the wordplay.
'sculpted' indicates an anagram (I've seen this in other clues).
'including' is an insertion indicator.
'duck' becomes 'o'.
'rodins' anagrammed gives 'indors'.
'indors' placed around 'o' is 'INDOORS'.
(Other definitions for indoors that I've seen before include "home" , "Within the four walls" , "Covered" , "Within house" , "safe from the weather" .)
