Workshop or artist's studio (7)
I believe the answer is:
atelier
This clue is a double definition.
'workshop' is the first definition.
(I've seen this before)
'artist's studio' is the second definition.
(I've seen this in another clue)
(Other definitions for atelier that I've seen before include "Tie earl up in the artist's place" , "room for artist" , "Artist's workshop, studio" , "I relate to workshop used by artist" , "Artist's studio (French)" .)
