Pad appropriate to house us at home without Oscar (10)
I believe the answer is:
pincushion
'pad' is the definition.
(I have seen 'small pad' mean 'pincushion' so perhaps 'pad' could also mean 'pincushion')
'appropriate to house us at home without oscar' is the wordplay.
'appropriate' becomes 'pinch' (I've seen this before).
'to house' indicates putting letters inside.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'pinch' going around 'us' is 'pincush'.
'in' enclosing 'o' is 'ion'.
'pincush'+'ion'='PINCUSHION'
(Other definitions for pincushion that I've seen before include "small pad" , "Sewer's aid" .)
