Bust I leer at in studio (7)
I believe the answer is:
atelier
'studio' is the definition.
(atelier is a kind of studio)
'bust i leer at' is the wordplay.
'bust' indicates anagramming the letters.
'i'+'leer'+'at'='ileerat'
'ileerat' anagrammed gives 'ATELIER'.
'in' is the link.
(Other definitions for atelier that I've seen before include "Tie earl up in the artist's place" , "Artist's workshop, studio" , "Designer's workshop" , "I relate to workshop used by artist" , "Artist's studio (French)" .)
