Summer-house (6)
I believe the answer is:
gazebo
'summer-house' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for gazebo that I've seen before include "Garden shelter" , "Small summerhouse for shade" , "Summer house with a wide view" , "Kind of garden summerhouse with wide view" , "Small summerhouse or open hut" .)
