From The NY Times
"It took three years to build, but the Emerald Art Glass House (named after the Zielinskis’ company, Emerald Art Glass) now hovers above the factory in the South Side neighborhood, overlooking the Monongahela River, railway line and bridges.
Eric Fisher, the couple’s architect, says proudly that the cantilevered extension is three times the length of the one at Frank Lloyd Wright’s Fallingwater. And that it recalls the tradition of the owner living over the shop."
It gives a lot of the back story of how it was built and the owners who built it. Also has a nice slideshow.
