The Main Line's 10 most expensive homes for sale

From a Gilded Age estate to a mansion with an indoor basketball court

View as Map

Editor’s note: This article was last published in June 2018 and has since been updated with the most recent information.

Here at Curbed Philly, we keep a very close eye on the real estate market within Philadelphia city limits. And sure, there are some big blockbuster listings that are truly something else. But if you're in the market for mega-mansions with 8-digit price tags, the Main Line is where to look.

This area consists of about 20 towns northwest of Philadelphia that were built along the main line of the Pennsylvania railroad during the 19th century. Today, the affluent communities are known for their schools for being some of the wealthiest zip codes in the nation.

Here, we've scoured the most current real estate listings in Main Line zip codes to find the 10 most expensive homes for sale, from a Gladwyne mansion with ties to the Campbell Soup family to the priciest property sitting on 32 acres.

Since the last update of this map in January 2018, there have been some big-time price cuts, new additions, and some mansions that have been knocked off the list.

The homes are listed in order from most to least expensive.

1. 100 Maple Hill Rd

100 Maple Hill Rd
Gladwyne, PA 19035

$19,900,000

Stats: 6 bedrooms, 7 full baths, 3 half baths, 16,528 square feet 

The skinny: Despite shaving millions off its original asking price, this Gladwyne mansion is still the most expensive home for sale on the Main Line. The nearly $20 million price tag buys you a fairly new home—it was only built in 2009—on 32 acres. Inside the mansion there's an indoor pool, movie theater, a professional-grade gym, and a wine cellar with tasting room. The grounds are just as impressive, with a tennis court on top of a plateau and a separate guest house.

2. Gladwyne Estate

Copy Link

$17,000,000

Stats: 7 bedrooms, 8 full baths, 4.5 half baths, more than 15,000 square feet

The skinny: Though not publicly listed on MLS, this Gladwyne estate is looking for its next owner to move into the custom built home, where many of the finishes have been locally sourced. There are grand details throughout, starting with the foyer featuring a double staircase, to the full court indoor basketball court, spa, and indoor pool (which then opens to the outdoors) to the tennis court. Oh, and did we mention there are two gourmet kitchens? It’s not the kind of place to have an open house, though. Because it’s privately listed, the only way to check it out is via private tours (and you’ll need an invite).

3. 1543 Monk Road

1543 Monk Rd
Gladwyne, PA 19035

$16,500,000

Stats: 8 bedrooms, 7 full baths, 3 full baths, 14,467 square feet

The Skinny: The Linden Hall estate is bonkers. The 50-acre estate dates back to 1928, and was home to the Dorrance family (of the Campbell Soup company) for two decades. Clearly, they lived the good life, with two pools, a tennis court, and gorgeous gardens. In total, the estate has multiple buildings, including the French Normandy-style mansion, a "caretaker's" building, a 10-car garage, stables, and a pool house. The mega-mansion has been on and off the market since 2013, and most recently chopped $3 million off its asking price.

4. 770 Godfrey Road

770 Godfrey Rd
Villanova, PA 19085

$14,900,000

Stats: 8 bedrooms, 9 full baths, 4 half baths, square footage n/a

The Skinny: After it was last listed in January, the Abermarle Estate in Villanova has dropped another cool $2 million off its asking price. Now, the nearly $15 million property costs a lot less than its original asking price of $25 million in 2012. The Albermarle in Villanova, about 45 minutes outside of Philly, sits on 16.93 acres and was once part of the Ardrossan, the Montgomery Scott family’s enormous estate. There’s also a restored clock tower with an office and a stone barn on the grounds.

5. 1530 Monk Road

1530 Monk Rd
Gladwyne, PA 19035

$9,990,000

Stats: 6 bedrooms, 9 baths, 14,738 square feet

The Skinny: This custom-built mansion in Gladwyne, which calls itself Westbourne Woods, just shaved off almost $3 million from its January asking price. The Colonial-style mansion sits on eight acres—there’s another 6.5 acres available for purchase. It’s extravagant, and highlighted by its private amenities: An indoor lap pool, a baseball batting cage, a gym, wine cellar, and movie theater.

720 N Spring Mill Rd
Villanova, PA 19085

$6,999,000

The Stats: 8 bedrooms, 9 full baths, 2 half baths, square footage n/a

The Skinny: This 1930s estate sits on five acres in Villanova and considers itself one of the last-remaining Gilded Age mansions on the Main Line. Along with impeccably landscaped grounds with an in-ground pool, each bedroom has its own fireplace.

929 Rock Creek Rd
Bryn Mawr, PA 19010

$5,985,000

The Stats: 6 bedrooms, 9 full baths, 3 half baths, 15,000 square feet

The Skinny: This stone-cold stunner sits on 1.83 acres in Bryn Mawr, managing to fit a salt-water pool, a pool house, and a carriage house outfitted with an apartment onto its grounds. The mansion is quite moody in a regal way, and each bedroom has its own bathroom suite made of marble. Bonus: There’s an in-house elevator. The home recently dropped nearly $1 million off its asking price.

$5,495,000

1820 Aloha Ln
Gladwyne, PA 19035

$5,350,000

The Stats: 7 bedrooms, 9 full bathrooms, one half bathroom, 12,401 square feet

The Skinny: Tucked back in Gladwyne on 2.6 acres of land is this countryside stunner. With a stone exterior, wraparound porch, infinity pool, and spa, this home feels like it was built for summer. It’s got gardens and lush green space galore, and inside, rooms like the kitchen (with a ton of counter space) and a wood den are evidence that the place is all about elegance. It’s also new to the market—it was just listed yesterday.

264 Abrahams Ln
Villanova, PA 19085

$4,500,000

The Stats: 7 bedrooms, 9 full bathrooms, 3 half baths, 13,500 square feet

The Skinny: You’re looking at the youngest property on this list. Built in 2017, this mansion overlooks Ardrossan Farms and sits on about two acres. The rooms are meant to impress: The family room has cathedral ceilings with exposed timbers and a floor-to-ceiling fireplace, and the kitchen has more cabinets than we can count. The estate recently dropped $500,000 from its asking price and threw in a 2018 Ferrari for buyers who purchase the home by the end of July.
