A 12.75-acre estate in Philadelphia’s priciest suburb has come to market for the first time asking $8.5 million. 

Located on Country Club Road in Gladwyne, one of a string of Philly suburbs known as the Main Line, the estate is home to a 9,166-square-foot mansion built in 1993. As of March, Gladwyne was the priciest ZIP code in Pennsylvania, with a median home price of $3.7 million, according to The Wall Street Journal. 

“It’s one of the most prestigious, sought-after locations within the entire Main Line,” said Lisa Yakulis of Kurfiss Sotheby’s International Realty, who listed the home last week. “It’s fairly densely populated, so to have a property of this scale with open private views is very unusual.”

The property belongs to heirs of the Smith family, which made its fortune in the oil business in the late 19th century with the founding of the Kewanee Oil Company. Today, the family is better known for the W.W. Smith Charitable Trust, a philanthropic foundation that supports local education and medical nonprofits. The seller was not immediately available for comment.

The property includes the six-bedroom manor-style home, a detached guest cottage, a pair of two-car garages and an additional building with a powder room that could become a pool house, Yakulis said.

The outdoor area includes a pool surrounded by rocks with an attached suite of amenities on the lower level of the main home, as well as multiple terraces and expansive gardens, according to the listing.

Despite its age, the inside of the home features a bright open floor plan that withstands the test of time, Yakulis said. The decor features oak floors, six fireplaces, a statement staircase, extensive paneling and a double-height great room anchored by a stone fireplace. In addition to the six bedrooms, there are staff quarters or an au pair room, as well as an entertainment room with a full bar, a wood-paneled library and a second kitchen.

Given the size of the property, there is an opportunity to subdivide it into several lots, and plans have been drawn up diagramming a three-lot option, according to the listing. 
The property has been in the Smith family since the early 1990s and was transferred to a trust in the name of several heirs in 2014, according to Montgomery County property records. The listing was first reported by the Philadelphia Business Journal.
