Architect with very bad English country home (9)
I believe the answer is:
nashville
'country home' is the definition.
(home of country music)
'architect with very bad english' is the wordplay.
'architect' becomes 'nash' (I've seen this before).
'with' says to put letters next to each other.
'very' becomes 'v' (abbreviation).
'bad' becomes 'ill' (similar in meaning).
'english' becomes 'E' (abbreviation).
'nash'+'v'+'ill'+'e'='NASHVILLE'
(Other definitions for nashville that I've seen before include "City in Tennessee" , "Capital of Tennessee and home of country music" , "Tennessee state capital" , "US city" , "Where the Grand Ole Opry comes from" .)
