Just off the main living space, the newly enclosed Florida room with floor-to-ceiling windows creates the perfect spot for morning coffee, sunset views, or hosting friends year-round.The kitchen was designed for both cooking and gathering, featuring granite countertops, quarter-sawn oak cabinetry, a six-burner cooktop, hidden stainless vent hood, and newer appliances.
