Frightful-looking refuges with no end of want (7)

I believe the answer is:

hideous

'frightful-looking' is the definition.

I cannot understand how the remainder of the clue works.

(Other definitions for hideous that I've seen before include "Extremely unpleasant" , "Ghastly" , "Horrible" , "Extremely ugly" , "revolting" .)

I've seen this clue in The Times.
