Building a place for demolition (6)
I believe the answer is:
palace
'building' is the definition.
(I have seen 'Large building' mean 'palace' so perhaps 'building' could also mean 'palace')
'a place for demolition' is the wordplay.
'for demolition' indicates an anagram (I've seen this in other clues).
'a'+'place'='aplace'
'aplace' anagrammed gives 'PALACE'.
(Other definitions for palace that I've seen before include "Large building" , "Royal dwelling" , "Official residence of a sovereign" , "Head of state's residence" , "very nice house" .)
