Tedious working alfresco (7)

I believe the answer is:

outside

'alfresco' is the definition.
('outside' can be a synonym of 'alfresco')

'tedious working' is the wordplay.
'working' indicates an anagram.
'tedious' is an anagram of 'OUTSIDE'.

(Other definitions for outside that I've seen before include "External surface" , "Tedious (anag)" , "Where smokers now often must go" , "Without" , "having emerged from the tunnel?" .)

I've seen this clue in The Telegraph.
