Marched around a building (4)
I believe the answer is:
arch
'a building' is the definition.
'marched around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'ARCH' is hidden in the letters of 'marched'.
(Other definitions for arch that I've seen before include "Roguish, cunning" , "Wellington's, perhaps" , "Mischievous - curve" , "Playfully superior" , "Clever" .)
