"The 512" on the mailbox identifies one of the most admired of South Devon's extraordinary older homes. Situated on a level, gorgeously landscaped 1-acre lot, this gracious Georgian-style home built in 1842 certainly has a long history but its most recent is the story of a home filled with love, laughter, children and lots of family and friends. Neighbors walking or driving by over the past 30+ years of the Seller's ownership marveled at the transformation from a rather nondescript 3-story old house to its present-day grandeur including a dramatic stone, side-facing covered porch entry, cedar siding and authentic architectural moldings and windows. The renovating began in earnest with 2003's reconfiguration of the entire back of the house. Designed for our modern open lifestyle, the new "hub" of this beautiful home includes a lovely CUSTOM KITCHEN with all the requisite updates: island w/seating and pendant lighting, granite counters, tile backsplash and flooring, wood cabinets, stainless double sinks, Wolf double wall ovens and warming drawer, 5-burner Dacor gas cooktop, Sub Zero refrigerator and back stairs to the 2nd floor. Adjoining the kitchen is a terrific BUTLER'S PANTRY and separate BREAKFAST AREA which leads into the warm, inviting FAMILY ROOM addition featuring a stylish, lighted Dome and coffered ceiling, custom built-in cabinet/bookcases, raised-hearth FIREPLACE and radiant-heated brick floor. The large wall of windows in both the Family Room and Breakfast Area allow for lots of natural light easily muted by the motorized window shades and exterior awnings. The more formal LIVING ROOM with built-ins and DINING ROOM with stunning crystal chandelier each also has crown molding, HW inlay floors partially covered with carpet and double French doors opening to the large private FLAGSTONE TERRACE w/covered awning and step-down to a fenced side yard. The entire first floor flows easily from one room to another making for entertaining nirvana. The second floor holds the spacious MBR w/new carpet, motorized window shades and adjoining MASTER BATH with double corian counter sinks; three generously-sized BR's and full bath; two additional BR's, a former BR converted into a large closet and full bath complete the third floor. Saving the best for last is the incredible backyard oasis filled with beautiful lighted trees, bushes and perennials offering seasonal delight as well as privacy surrounding the heated IN-GROUND POOL AND SPA! A separate POOL HOUSE/FULL BATH for easy swimsuit changing and a lovely FLAGSTONE PATIO with pergola and a motorized canopy offers a peaceful, serene warm-weather refuge at your doorstep. Add'l features include: 1st Floor with 9' ceilings; and 2nd Floor with 8'6" ceilings; backyard fencing w/two gates; driveway has add'l parking on side yard and has motorized gate; irrigation system for front and back yards; whole house generator; 2-car detached garage; Sonos stereo system for interior and pool area; newer septic system, basement French drain/sump pump and oil boiler; plantation shutters on many windows.
