Built with a significant emphasis on quality and sustainability, the European-influenced "San Souci" is offered for the first time. Convenient to Newtown, Yardley and New Hope, this home is a world away from typical newer construction, this privately situated, custom residence is on 5.9 acres high above the historic Delaware River canal, perfectly located for walking and bicycling as well as for easy access to Princeton, Philadelphia, and train service to New York and beyond. Step inside this LEED-certified home and feel how open and light-filled the entire main living level is. Custom Andersen windows and doors galore frame views and let the sunshine in on timeless marble floors. A Canadian-built soapstone wood-burning fireplace can warm the living space for hours, supplemented by the home's efficient geothermal and solar systems with hot-water radiant tubing in place beneath most of the home's floors. The open plan is flexible and smartly designed with spaces for dining, including a charming hidden breakfast nook, seating areas, a private home office, a four-season sunroom with fireplace and a stunning kitchen. Designed for the serious cook, the kitchen has storage galore with a walk-in pantry closet and custom Amish-made cabinetry, professional-grade Thermador appliances (two full-size wall ovens, warming drawer, 48" gas cooktop with powerful ventilation hood, refrigerator/freezer, dishwasher), wine chiller, built-in microwave/convection and a large island topped in a single sheet of granite, all lined in fun LED rope lighting. Whether for daily needs or special occasions, this kitchen will perform quite capably, and the cook will appreciate the views. This home has a remarkable amount of indoor-outdoor flow, including access to a deck with built-in seating and BBQ space just off the kitchen, a large corner veranda off the dining area and a patio with built-in firepit and seating off the sunroom.
