137 Bay Street represents one of the last opportunities of its kind-for the buyer who understands the difference between what is and what's coming. On nearly half an acre in the heart of Sag Harbor Village, with open views to Havens Beach and Sag Harbor Bay, the existing home offers an immediate presence. But the real value lies in what can be created here. Bay Street is in the midst of a clear evolution, with significant homes being reimagined and rebuilt. Properties with this scale, light, and proximity are increasingly rare-and becoming harder to replicate. For those who see where the market is going, the path is straightforward: expand, elevate, and fully realize a setting that already speaks for itself. Walk to the beach. Walk to the village. Build something that belongs.
