Packed White House? (5)
I believe the answer is:
igloo
'white house?' is the definition.
(an igloo is white in colour)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for igloo that I've seen before include "From domed hut" , "Dome-shaped Eskimo house" , "Innuit dwelling" , "cold accommodation" , "Inuit building" .)
