Welcome to the ultimate-private world of DeepDene, a Gilded Age country estate minutes from the center of Chestnut Hill. Built at the turn of the 20th century by James Gowen, an executive for Pennsylvania Railroad. Redesigned and expanded by Willing, Sims and Talbutt in 1930. DeepDene shares its unusual name with the notorious 104+carat brilliant DeBeers yellow diamond, generally believed to be the largest irradiated yellow diamond in the world. While it remains a mystery if the diamond was named for the estate or vice-versa, one thing is perfectly clear. This coveted property is much more than just a luxury home. Surrounded by its own 3.7 acre manicured parkland setting, DeepDene is found at the end of a private road, behind iron gates and a long winding driveway—just beyond the city limits.
