About This Home

686 Knob Hill Court

Welcome to one of Argyle's most distinguished estate properties. Positioned at the end of a secluded cul-de-sac within the prestigious Estates of Pilot Knob, this custom residence offers an exceptional blend of space, craftsmanship, and convenience across 2.5 wooded acres. Surrounded by mature trees and manicured grounds, this 5,683-square-foot home provides a peaceful setting while remaining minutes from shopping, dining, major thoroughfares, Argyle ISD, and premier private schools. Designed for comfortable living and memorable gatherings, the versatile floorplan features 5 bedrooms, 5.5 baths with a 4 car garage, two staircases, and flexible living areas. Two bedrooms are located on the main level, including the expansive primary suite, creating an ideal arrangement for multi-generational living, guests, or changing household needs. Inside, extensive millwork, hardwood floors, built-in cabinetry, and expansive windows create an atmosphere that is both welcoming and refined. The executive study offers a dedicated workspace, while the family room is highlighted by vaulted ceilings, exposed beams, and views of the outdoor living areas. The kitchen combines function and style with a generous center island, double ovens, gas cooktop, custom cabinetry, and seamless flow to the surrounding gathering spaces. Additional amenities include a media room, game room, fitness room, and bonus flex spaces. Outside, a resort-style pool and spa, spacious patios, and a heavily treed backdrop create an ideal setting for entertaining, relaxing, and enjoying the property's natural beauty. The circular drive and side-entry three-car garage enhance the home's curb appeal. Rarely does an estate of this caliber become available. Combining acreage, acclaimed schools, sought-after amenities, and an exceptional location, this property offers a lifestyle increasingly difficult to find in North Texas.
