Little bit in your houses (4)
I believe the answer is:
tiny
'little' is the definition.
(similar in meaning)
'bit in your houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'TINY' is hidden in the letters of 'bit in your'.
(Other definitions for tiny that I've seen before include "Extremely small" , "Little" , "with sharp points?" , "Microscopic" , "- - Tim (Dickens)" .)
