A gorgeous modern stucco and wood exterior and pristine landscaping optimize curb appeal. Walls of glass and aluminum European tilt-and-turn windows invite in brilliant natural light and showcase bucolic vistas of farm fields and lush greenery. The private backyard oasis is as exceptional, featuring a sparkling 20x50 heated gunite saltwater pool with sundeck and infinity=edge spa surrounded by 2,300 square feet of stay-cool porcelain bluestone for lounging and entertaining. Striking 8-foot aluminum European patio doors open with one hand for seamless indoor-outdoor living.

The airy double-height living room is anchored by an elevated gas fireplace wrapped in stone and flanked by horizontal boards. Imported European custom cabinetry, a 10-foot center island clad in Calacatta Quartz, and a suite of professional appliances set the tone for the chef. This beautiful house also presents first and second-floor primary bedroom suites and a rear staircase that accesses a private space - perfect as a home office or studio.
