Promising site: Hill House Publishing Company – A Celebration of Victorian House Design. No affiliation, haven’t fully checked it out. I did order one of the free posters.
Do you have a fondness and fascination for old houses? If so, this site is for you!
Check out this website – these are American, but still of that era. Very SL suitable.
