Open porch (7)
I believe the answer is:
veranda
'open porch' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for veranda that I've seen before include "balcony" , "Porch - portico" , "Stoop" , "Covered porch on building" , "Roofed gallery beside a house" .)
