GOLD COAST COUNTRY ESTATE     A long, private driveway leads to the gravel courtyard of this stately ivy-covered manor home nestled amidst 2.4 bucolic acres on the original Louis Comfort Tiffany estate. Once owned by Tiffany's granddaughter, this incredible residence has been beautifully renovated with modern amenities.     The soaring two-story foyer is clad in crisp white raised-panel millwork and leads to a gracious formal living room and dining room, each with a fireplace and glorious views of the manicured property. The chef's kitchen features bespoke fitted cabinetry with butcher block perimeter counters, a large center island with seating topped with honed Danby marble, a fireplace, designer tile, high-end fixtures and fittings, professional-grade appliances, and a lovely breakfast area surrounded by wall-to-wall windows overlooking the patio and lush lawn.
