Single Family Residence for sale in Siena
Overview
Property Description
This 3,920-square-foot custom home blends everyday function with standout style from the moment you walk in. Soaring two-story ceilings crown the great room, where a 60-inch electric fireplace rises against a dramatic floor-to-ceiling tile feature wall. Rich wood flooring runs throughout, eight-foot interior doors elevate the entire first floor, and a French-door study with a board-and-batten accent wall makes the perfect work-from-home retreat. The chef's kitchen stuns with European-style cabinetry, a six-burner gas cooktop, double-wall ovens, and a built-in microwave. An oversized island is anchored by a professional-grade pull-down faucet plus a second prep sink, while a walk-in pantry with custom shelving keeps everything in its place. Custom built-in shelving and display niches in the kitchen and entry add character, and a wine cooler and brand-new Electrolux French-door refrigerator come ready to go. Retreat to the primary suite, set off by its own board-and-batten accent wall and a spa-inspired bath featuring a freestanding tub, frameless glass walk-in shower with built-in niche, and dual-sink quartz vanity. The oversized walk-in closet is fully outfitted with custom built-in shelving and dual hanging. With five bedrooms and four full baths, there's room for everyone. Upstairs, a game room/loft flex space with a built-in desk nook offers endless flexibility, and a private mother-in-law suite with a walk-in shower is ideal for guests or multigenerational living. Secondary baths feature tile-surround tub/shower combos. Outdoor living shines with a covered back patio and full outdoor kitchen—built-in cooking station, sink, and refrigerator—ready for year-round entertaining. Peace of mind comes standard: a whole-home Generac generator, tankless gas water heater, and full irrigation system. The stone-and-stucco elevation with a standing-seam metal roof porch accent completes a home that's as durable as it is beautiful.
