Welcome to Square Pond Farm! Nestled in the scenic countryside of Carroll County, Maryland, this breathtaking 48-acre estate offers a harmonious blend of historic charm and modern luxury. The property boasts approximately 10 acres of pasture, 32 wooded acres, and a beautifully curated 6-acre homesite, all bordering the pristine lands of Prettyboy Reservoir—providing direct access to horseback riding and hiking trails. At the heart of the farm stands a stunning 27-year-old modern farmhouse, thoughtfully designed on the original homestead site of a century-old farming family. This home seamlessly blends old-world character with contemporary conveniences, featuring soaring 9' and 10’ ceilings, rich wood floors, and a standing seam metal roof. Expansive windows and transomed doors flood the living spaces with natural light, while a wrap-around covered porch invites you to relax and take in the serene views. Inside, the gourmet kitchen is a chef’s dream, complete with soapstone countertops, 42” maple cabinetry, a Kitchen Aid commercial-style fridge, double convection ovens, a separate cooling fridge, and an under-counter icemaker. Additional highlights include a spacious living room with a converted gas fireplace, a grand 20’ entry foyer, and two master suites—one on the main level and another upstairs. This estate is built for both comfort and efficiency, featuring zoned heating and cooling, a whole-house propane generator, updated HVAC systems, and a unique integrated corn furnace. The property is fully equipped for farming, equestrian, or hobbyist pursuits with a 30’ x 26’ bank barn, tack room, green/grow house, workshop, equipment shed, and a two-car detached garage. Outdoor amenities include an ornamental pond with a waterfall and pier, a large spring-fed pond, a firepit area, and a beautifully tiered stone garden with exceptional plantings, walkways and waterfalls. Whether you're seeking a private retreat, an equestrian haven, or a sustainable homestead, Square Pond Farm is a rare gem that offers it all. Don’t miss the opportunity to own this extraordinary slice of Maryland countryside!
