Through historic stone gates along the storied Blackburn Road, Gladmore Farm emerges as a rare offering in one of Sewickley Heights’ most coveted settings. Elevated and private, the 6.7-acre grounds pair the enduring grace of early 20th-century craftsmanship with the promise of an extraordinary future. The existing residence, thoughtfully reimagined, offers four ensuite bedrooms and a luminous, decorator-designed kitchen. A long, winding approach reveals a home hidden from view, enveloped in quiet seclusion. Here, the legacy of Gladmore Farm becomes the foundation for your vision—whether preserving its refined presence or creating an entirely new estate on this unparalleled high-elevation site. In this exclusive enclave, history and possibility meet in timeless harmony.
