Crews were called around 6:30 a.m. Sunday to the LuLu Country Club on the 1600 block of Limekiln Pike in Glenside for reports of smoke coming from the basement.
Arriving firefighters were met with smoke and flames coming from the facility and quickly called in a second alarm.
"It's a heavy timber roof and a large open attic space so once we arrived the fire had already gotten into the attic space so it's very difficult at that point," said Chief Eric Clauson with the Fort Washington Fire Company.
More than 100 firefighters responded to the scene.
"Some of those hydrants are 2000, 2500 feet away so we needed extra companies to come assist us with getting those water supplies established," said Clauson.
Officials said the fire appears to have started in a locker room, but the investigation is ongoing.
The historic building, which opened in 1912, according to the club's website, has been renovated several times in recent years.
But after the blaze, it is considered a total loss.
Heartbroken members watched the building fall to pieces, many were on site to take in the second day of a golf tournament.
"It meant everything, it was my tree house, it's where I came to relax," said David Cagnetti, a club member. "I'm retired so I come here to play cards, eat, play golf."
"I think we're all trying to absorb what's happening here, and speculate as to what happened exactly, but that's what were here to find out this morning and go on from there," said former president Paul Muller.
Initial reports stated a person had been hospitalized, but Action News is now being told no one was hurt.
The fire marshal is still investigating.
