A number of classic homes on West Paces Ferry near the Governor's mansion in Atlanta have been razed over the years and replaced with McMansions. Of course, the only way to preserve a historic, classic home is to set up a trust and donate it to a foundation with the stipulation that it can't be razed or excessively remodeled. But heirs usually want the money and don't care about preserving buildings.
It is always interesting how people want to control other people's property, which costs them nothing to do.
