Today's marketplace brings us two East End trend-setters: one of the first houses in Montauk to incorporate a "green roof" and the first recorded property on a circa 1840 map of Sag Harbor. The sleek Montauk pad is priced at $2.7 million and offers distant views of Lake Montauk, a swanky rooftop deck, and lots of typical modernist fixtures. The historic Sag Harbor cottage, which is offered for under $695,000, touts a location near the Ross School, 12" wide plank floors, and more exposed beams than you'll know what to do with. Mm, it's good to be first.
