A row outside the Spanish workshop (7)
I believe the answer is:
atelier
'workshop' is the definition.
(I've seen this before)
'a row outside the spanish' is the wordplay.
'row' becomes 'tier' (a tier is a row of things).
'outside' means one lot of letters goes inside another (some letters go outside others).
'the spanish' becomes 'el' ('the' in Spanish).
'tier' placed around 'el' is 'telier'.
'a'+'telier'='ATELIER'
(Other definitions for atelier that I've seen before include "I relate to workshop used by artist" , "Designer's workshop" , "Artist's studio (French)" , "Tie earl up in the artist's place" , "Artist's workshop, studio" .)
