Crossword Genius

A lawyer unchaste characters house (5)

Ross

I believe the answer is:

dacha

I'm a little stuck... Click here to teach me more about this clue!

'house' is the definition.
(I know that dacha is a type of house)

'a lawyer unchaste characters' is the wordplay.
'a lawyer' becomes 'da' (abbreviation for District Attorney).
'unchaste characters' becomes 'cha' (I can't explain this - if you can you should give a lot more credence to this answer).
'da'+'cha'='DACHA'

Can you help me to learn more?

(Other definitions for dacha that I've seen before include "Russian holiday cottage" , "Russian's second home in the country" , "Second home in the country for Muscovites?" , "Russian retreat" , "Russian villa" .)

I've seen this clue in The Daily Express.
