Colonnaded entryway (7)
I believe the answer is:
portico
'colonnaded entryway' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for portico that I've seen before include "covered area" , "Covered porch, perhaps with columns" , "Roofed porch" , "Colonnade in front of a building" , "Covered porch with supporting columns" .)
