BALTIMORE (AP) — Baltimore is considering banning new construction that uses Formstone, the fake stone that covers block after block of rowhomes across the city.

The faux stone facades carved out of colored concrete would be banned for new construction if an overhaul of the city’s zoning code is passed as introduced in October.

Waters told The Baltimore Sun the proposal is ludicrous. The off-beat film director says he thought the fake facades were ready for a comeback, describing them as positively postmodern.
