Town Line Road, a thoroughfare straddling the towns of Southampton and East Hampton, is the site of a trio of listings — priced at a total of $45 million — that all sold within a span of five months.

Corcoran Group broker Gary DePersia, who unloaded the pricey pickings, also sold two contiguous Val Florio-designed, Lifton-Green-built homes in Wainscott, listed for $14.9 million and $16.95 million, respectively, on the east side of the road.

“It’s the Hamptons’ new hot address with new construction being king on both sides of the road, and Wainscott challenging the supremacy of Sagaponack,” DePersia told Patch.

The area’s popularity, DePersia said, is largely thanks to room for growth on the road’s East Hampton side, where the town has been more generous and imposed fewer building restrictions than in nearby Sagaponack.

One recent sale in the area, a $13.95 million house developed by builder Michael Frank in Sagaponack, took full advantage of the relaxed rules in the construction of a compound with 11,000 square feet of living space. With new zoning rules likely on the horizon in the area, DePesia told Patch that he doubts such a structure will be duplicated. [East Hampton Patch] — Julie Strickland
