Carrier succeeded rebuilding chalet (7)
I believe the answer is:
satchel
'carrier' is the definition.
(I've seen this before)
'succeeded rebuilding chalet' is the wordplay.
'succeeded' becomes 's' (genealogical abbreviation).
'rebuilding' indicates anagramming the letters.
'chalet' anagrammed gives 'atchel'.
's'+'atchel'='SATCHEL'
(Other definitions for satchel that I've seen before include "Get school item" , "Bag -- latches (anag)" , "Schoolbag for children's books" , "Bag with a flap and strap" , "Schoolchild's carrier" .)
