About 136 Old Post Office Rd

Step into the enchanting beauty of Sweethome Ranch, a breathtaking private mountain estate spanning 40 fully fenced acres. Flanked on two sides by BLM land and National Forest, this rare retreat is just minutes from Downtown Boulder yet feels like a secluded paradise. Wander through vibrant meadows of wildflowers, towering Douglas Fir and Blue Spruce, and stunning Aspen groves, all nourished by perennial springs that weave through the property. The main house, a masterpiece of Pueblo-style architecture, features traditional adobe brick and plaster walls, magnificent log beams, and exquisite Saltillo tile flooring, with distinct elements sourced from New Mexico. At the heart of the home is a welcoming main living area that seamlessly blends a cozy family room, formal dining space, and a fireside living room, all surrounding the chef's kitchen. This culinary haven showcases custom blue beetle kill pine cabinetry, top-tier appliances, and a grand central island with butcher block counters. The primary suite is a sanctuary of comfort, boasting an ensuite bath with a walk-in shower, soaking tub, built-in storage, and a private sitting room. Down the hall, discover a charming library with built-in bookshelves, a guest bedroom, a versatile study that can serve as a non-conforming bedroom, and a spacious mudroom. Additional highlights include a wine cellar closet, oversized pantry, laundry room, and more. Designed for exceptional energy efficiency, the adobe construction is complemented by solar hot water in-floor heating and a robust 9.44 kW solar PV system. This estate also offers a detached two-car garage with an upper-level studio, a 1600 square foot barn featuring a loft and a full in-law apartment, loafing sheds, and usable level pasture areas. Sweethome Ranch is a rare find, exuding character, history, and a timeless sense of tranquility. Experience the magic of this extraordinary mountain retreat.
