Welcome to Shelly Mill, an extraordinary Bucks County estate where more than 250 years of American history, exceptional craftsmanship, and modern luxury come together to create a private, resort-like lifestyle unlike anything else on the market. Privately positioned behind gates on nearly 9.5 magnificent acres, 3111 Burnt House Hill Road traces its origins to 1771, when it served as the Ely family gristmill and played a role in the region's early grain-processing history. Following a major renovation in 1998 and thoughtful updates since, the original three-story stone mill has been transformed into an extraordinary residence while preserving the architectural elements that make it truly irreplaceable. At the heart of the nearly 9,500-square-foot home is its completely preserved 18-foot-diameter millhouse waterwheel, dramatically integrated into the main-floor interior as both a piece of history and a work of art. Throughout the residence, original mill details remain on remarkable display, including grand interior doors, massive interlocking exposed timber beams, soaring ceilings, reclaimed leaded and stained-glass windows, and thousands of decorative turn-of-the-century Boston Grueby tiles adorning floors and walls. A spectacular 35-foot river-stone fireplace anchors the main living spaces, while skylights, expansive windows, and French doors fill the interiors with natural light. The open floor plan creates an effortless connection between living, dining, and entertaining spaces while maintaining the warmth and character of the original mill. The gourmet kitchen brings modern functionality into this historic setting with upgraded countertops, a generous island, casual dining space, walk-in pantry, and convenient kitchenette. A separate formal dining room and an entertainment room with a bar provide additional spaces for hosting on both an intimate and grand scale. With six bedrooms, four full bathrooms, and four half bathrooms, including three bedrooms on the main level, the home offers exceptional flexibility for guests, home offices, and multigenerational living. An elevator and additional stairway provide convenient access throughout the residence, while custom fixtures, built-ins, and carefully preserved architectural details make every room feel distinct. The grounds are equally extraordinary. A saltwater pool, expansive bluestone terraces, mature kitchen gardens, sweeping lawns, a barn, chicken coop and established trees create a completely private, resort-like setting designed for entertaining and enjoying the natural beauty of Bucks County. A detached four-car garage offers oversized vehicle and storage capabilities, ample additional parking, and a connecting studio space ideal for a home office, art studio, recreation room, or guest quarters, complemented by a neighboring half bathroom. Perfectly situated in the heart of Bucks County, Shelly Mill provides remarkable privacy while remaining convenient to Doylestown, New Hope, and Peddler's Village. There are beautiful homes, historic homes, and luxury estates, but there is nothing else quite like Shelly Mill. From its 1771 origins and preserved working history to its monumental waterwheel, extraordinary Arts & Crafts details, and nearly 9.5 acres of private grounds, this is an estate that could never be recreated today. More than a home, Shelly Mill is a living piece of Bucks County history, and an opportunity unlikely to come to market again.
