421 N Boundary Rd Mill Spring, NC 28756

Discover the ideal balance of luxury, privacy, and mountain living at 421 North Boundary Road, a stunning 5,164-square-foot residence with five spacious bedrooms including dual luxury primary suites—an ideal setup for multigenerational living, guests, or those seeking flexibility for dual-suite lifestyles and aging in place. Set on 6.21 acres of wooded, usable land, this home is surrounded by mature hardwoods, private walking trails, and professionally designed landscaping by Van Powell, creating a mountain sanctuary. Enjoy direct access to the Lake Adger Trail System with over 15 miles of protected equestrian and hiking trails, and a deeded boat slip that provides convenient access to the lake without the maintenance of a waterfront home. Indoor and outdoor living blend seamlessly with screened porches, stone patios, covered verandas and open decks, all connected by charming garden trails that wind past stone walls, perennial plantings, and a tranquil goldfish pond with cascading waterfall. The heated indoor pool addition (2013) offers year-round enjoyment in a fully climate-controlled environment adjacent to garden and deck areas. The property has been meticulously maintained with a pre-listing inspection available, two encapsulated crawl spaces, UV-tinted Low-E windows, central vacuum, HEPA air filter, humidifier, whole-yard sprinkler system, three regularly serviced HVAC zones, automatic propane generator for essential spaces, a 508-foot deep well with new pump (2024), and a five-bedroom septic system with three holding tanks. Designed for comfort and elegance, the main level includes two primary suites: the original 1,000-square-foot cottage built in 2002, now a private suite with open living room and kitchen, stacked-stone gas fireplace and updated systems, and the main house (added in 2006), which features a grand two-story entry, arched doorways, thick crown molding, Santos Mahogany hardwoods, custom granite kitchen, double-sided fireplace, and a spa-inspired primary bath with sun tunnel and heated floors. The daylight walkout lower level is fully finished with a large studio/rec room, full bath and DryCore subflooring, creating flexible space for hobbies, recreation or a home office. Additional amenities include a fully heated and cooled utility barn/workshop/greenhouse combo with power, cold-water sink and equipment carport, and a three-car garage with two bays at the main level and one at the barn, all with ample storage including pull-down attic access. In the Lake Adger community, this home benefits from 3,250 acres of conservation land, 14.5 miles of shoreline, underground utilities, paved roads, high-speed internet, and community architectural standards that preserve beauty and value. The peaceful, non-commercial lake prohibits jet skis and water skiing, but is ideal for boating, kayaking and fishing. Ideally near Tryon, Saluda, Lake Lure, Hendersonville and Asheville, with close access to Green River adventures, vineyards, hiking, ziplining, and the Tryon International Equestrian Center, this retreat offers convenience and seclusion. 421 North Boundary Raod is more than a home—it’s a private retreat designed for a life of comfort, connection and natural beauty in western North Carolina.
