Mainly Military/MBG used to have some reasonable looking resin ones including a manor house that looked quite good.
When they retired I think Caliver picked up the moulds.
Other options, Hovels had some resin pieces, 4Ground have some MDF half-timbered pieces.
If you're ever in Scarborough I have a few that you could see.
Otherwise I could try and get out the old box-brownie and load up with 35mm
