Country lane — palatial houses (5)
I believe the answer is:
nepal
'country' is the definition.
(I know that Nepal is a Asian country)
'lane palatial houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'NEPAL' can be found hidden inside 'lane palatial'.
(Other definitions for nepal that I've seen before include "Himalayan republic" , "mountain state" , "Small country high in the Himalayas" , "place in the mountains ..." , "hilly part of Asia" .)
