Set within the rolling hills of Chester County and tucked into one of Hartefeld's most private enclaves, 100 Pyles Mountain Lane is a rare offering where architecture, craftsmanship, and lifestyle come together seamlessly. Designed by the renowned Bernardon architects, this custom-built home was thoughtfully created to reflect the charm and authenticity of a 19th-century Pennsylvania farmhouse all while delivering the modern layout and amenities today's buyers expect. Positioned on 1.3 acres it's one of the largest and most private lots in the community. The property captures sweeping fairway views and a sense of tranquility. Inside, timeless details take center stage. Reclaimed random-width pine floors, rich millwork, paneled walls, and period-inspired mantels create warmth and character throughout. The expansive kitchen is both functional and refined, featuring Viking and SubZero appliances, while the adjacent living spaces are designed for both everyday living and effortless entertaining. A first-floor primary suite is set within its own private wing, complemented by a dedicated home office and beautifully curated gathering spaces that flow seamlessly to the outdoors. The walkout lower level with 10-foot ceilings, brick flooring, it's own kitchen, bath, and open living space offers incredible flexibility for guests, extended stays, or entertaining. Upstairs, three generously sized bedrooms and two full baths provide ample space for family and visitors alike. Outside, the lifestyle truly unfolds. A screened porch, expansive hardscaping, and an elevated fire pit create the perfect setting to take in sunset views over the fairway. A detached two-story barn has been thoughtfully reimagined as a sophisticated recreational space that is ideal for hosting, unwinding, or creating your own retreat. Enjoy peace of mind with a brand-new 50-year, triple-layer roof, updated HVAC, refinished floors, and fresh paint throughout-allowing you to simply move in and start enjoying your new home. Life in Hartefeld National Golf Club extends far beyond the home itself. This offering includes a one-year social membership, providing access to the clubhouse, dining, events, and rounds of golf, bringing a true country club lifestyle right to your doorstep. This is more than a home - it's a setting, a lifestyle, and a level of design rarely available in Hartefeld. This is Chester County living at it's finest.
