Garden shelter made for Carol's outside being reassembled (4,5)
I believe the answer is:
cold frame
'garden shelter' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'made for carol's outside being reassembled' is the wordplay.
'outside' suggests removing the centre.
'being reassembled' indicates an anagram.
'carol' with its middle taken out is 'cl'.
'made'+'for'+'cl'='madeforcl'
'madeforcl' with letters rearranged gives 'COLD FRAME'.
Can you help me to learn more?
(Another definition for cold frame that I've seen is " Nursery provision".)
