Shame about empty gardens in Berkshire home (6)
I believe the answer is:
pigsty
'berkshire home' is the definition.
(a Berkshire is a type of pig)
'shame about empty gardens' is the wordplay.
'shame' becomes 'pity' ('pity' can be a synonym of 'shame').
'about' means one lot of letters goes inside another.
'empty' means to remove the middle letters.
'gardens' with its middle taken out is 'gs'.
'pity' placed around 'gs' is 'PIGSTY'.
'in' acts as a link.
(Other definitions for pigsty that I've seen before include "Without boots" , "Porcine pen" , "dump" , "Dirty place; animal pen" , "Very dirty house" .)
