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