Lofts, garrets (6)
I believe the answer is:
attics
I believe this clue is a double definition.
'lofts' is the first definition.
('attic' can be a synonym of 'loft')
'garrets' is the second definition.
('attic' can be a synonym of 'garret')
(Other definitions for attics that I've seen before include "Lofts, garrets" , "Static in top rooms" , "Space just below the roof" .)
