Extremely disorderly and disagreeable house (7)
I believe the answer is:
dynasty
'house' is the definition.
(I've seen this before)
'extremely disorderly and disagreeable' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'and' is a charade indicator (letters next to each other).
'disagreeable' becomes 'nasty' (similar in meaning).
'disorderly' with its centre removed is 'dy'.
'dy'+'nasty'='DYNASTY'
(Other definitions for dynasty that I've seen before include "Series of hereditary rulers" , "TV series" , "Power line" , "Succession of relatives" , "royal family" .)
