- Earth Day (April 22) saw the opening of the first “green” spec house in Southampton Village. On the outside, the house looks much like any other elegant house, except for the unobtrusive solar panels on the roof. The walls are stucco, the roof is tiled with gray, blue-gray, and terra-cotta-colored slates. But those beautiful roof tiles? They're actually made of recycled soda bottles. You'd never know it to look at them. And that's just the beginning.
