'more than one dwelling' is the definition.
I can't judge whether this defines the answer.

'is screened badly' is the wordplay.
'badly' indicates an anagram.
'is'+'screened'='isscreened'
'isscreened' anagrammed gives 'RESIDENCES'.

Can you help me to learn more?

(Another definition for residences that I've seen is " homes break up".)

I've seen this clue in The Irish Independent.
