Puts up, as a building (6)
I believe the answer is:
erects
'puts up as a building' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for erects that I've seen before include "Put up, builds" , "Sets up or builds." , "Puts up, stand or building" , "Puts up, say building" , "Secret (anag.)" .)
