Huts demolished like this (4)
I believe the answer is:
thus
'like this' is the definition.
(I've seen this before)
'huts demolished' is the wordplay.
'demolished' is an anagram indicator.
'huts' with letters rearranged gives 'THUS'.
(Other definitions for thus that I've seen before include "As a result" , "In this way" , "In this manner" , "an original Christmas gift" , "'So, therefore (4)'" .)
