"This is the model for the future of suburban town centers," developer Dean Adler told Action News last November, describing what he wants to build where the middle of Plymouth Meeting Mall stands today. "We take it down, and you know what we put in its place?" he asked. A youth sports complex, glass towers, restaurants, hotels.

None of that exists yet. The demolition Adler is describing, the one between Boscov's and Dick's Sporting Goods, isn't scheduled to start until 2027, with an opening projected for 2028. As of this summer's reporting, the sale of the mall's core to Adler's firm, LA Partners, still hadn't closed publicly, and the project still needs approvals nobody has voted on.

Meanwhile, three apartment buildings within a half mile of that same intersection are already leasing units, pouring foundations, or clearing zoning votes. If you've noticed a fenced-off office tower on Germantown Pike or wondered why the old DoubleTree suddenly went dark, that's not the town center. That's the part of this story that's actually moving.

What's already got an address

The most visible change is Monarq, the 175,000 square foot office tower at 500 W. Germantown Pike that sat mostly vacant for years while Keystone Development tried and failed to find office tenants, then tried and failed to convert it into a long-term care facility. Keystone finally got conditional use approval to turn it into apartments instead, about 150 units, with a fitness center, indoor pool, and coworking space. Construction started in 2025 with the first phase targeted for completion in early 2026, which puts it either open now or close to it.

A few minutes away, the former DoubleTree Suites at 640 Fountain Road closed its doors in late November 2025 after 253 rooms of business travelers stopped being enough to keep a hotel afloat two decades into the Route 476 interchange's transformation. Plymouth Township's Zoning Hearing Board voted 3-1 in February to let the six-story building become 213 apartments, a mix of 173 one-bedrooms and 40 two-bedrooms.

Then there's the third piece, still stuck in the queue. PREIT, which still owns the mall's Whole Foods side, wants to demolish the old IKEA office building on that end of the property and build somewhere between 275 and 300 more apartments, depending on which version of the plan you're reading. That approval hasn't come through yet.

Add those up and you get a local outlet's own math on this, not mine. MoreThanTheCurve, which has covered every zoning hearing on this property for years, estimated back in February that the pipeline adds up to somewhere in the neighborhood of 938 apartments coming online across Plymouth Meeting over the next five to ten years. That number includes Adler's 280 units inside the eventual town center, which means even the flashiest part of this story is one line item in a much larger residential build-out that's already underway without it.

The plan that keeps making headlines without breaking ground

None of this is a knock on what Adler is proposing. A 500,000 to 700,000 square foot youth sports complex with indoor and outdoor fields, a community pool, and an ice rink would be a genuinely new kind of destination for a county that mostly sends its travel teams to fieldhouses in Berks or Bucks. The mall has been losing relevance since Macy's closed in 2017, and Adler's track record includes taking, in his words, "obsolete but prime assets" and making them work again.

But track the coverage month by month and a pattern shows up. November 2025: the sale is announced, under contract. February 2026: still under contract, no closing confirmed. May and June: LA Partners is "under contract," the mall's own website still lists PREIT as the owner. July: still described as "if approved," with a construction start pushed to 2027. That's eight months of a deal that keeps getting reported as close but not closed, on a project that needs traffic and zoning approvals nobody has scheduled a public hearing for yet.

Compare that to Monarq, which went from a struggling office building to active construction in under two years once the conditional use was granted, or the DoubleTree, which went from closed hotel to an approved 213-unit apartment plan in about three months. The difference isn't ambition. It's that apartment conversions inside existing zoning move through Plymouth Township fast. A full demolition and rebuild that changes the identity of a 110-acre regional landmark does not, and shouldn't.

What's still open while all of this sorts itself out

Here's what hasn't changed: you can still take the kids to LEGOLAND Discovery Center, catch a movie at the AMC, grab groceries at Whole Foods, or watch a game at Miller's Ale House or Dave & Buster's. Boscov's, Burlington, Dick's Sporting Goods, and Edge Fitness are all still where they've been. Whatever LA Partners eventually builds in the interior between those two anchor stores, the rest of the property is running on its normal schedule.

There's a nice bit of history buried in why this site has always been in motion. When it opened in October 1966, Plymouth Meeting Mall was the third fully enclosed shopping mall built in the Philadelphia area, designed by Victor Gruen, the architect credited with inventing the modern American mall in the first place. Nineteen years later, IKEA opened its very first U.S. store on an outparcel here, in 1985, before outgrowing the space and relocating a few miles south to Conshohocken in 2003. This property has been reinventing itself since before most of its current shoppers were born. The current round is just the biggest one.

The freshest sign of that ordinary churn is a few minutes up Ridge Pike, not even on the mall property. Naya, a fast casual Lebanese chain out of the New York and New Jersey markets, is taking over the old Five Guys spot at 200 Ridge Pike in the Plymouth Square Shopping Center, near the Weis and the REI. New signage went up this summer. No opening date has been announced yet, but it'll be the chain's first location in Montgomery County and only its second in Pennsylvania. It's a small thing next to a $100 million redevelopment, but it's the kind of small thing that tells you the surrounding retail corridor is still healthy enough to attract a chain making its first move into the county.

What to actually watch for this fall

If you live near the mall and want a read on when things will start feeling different, don't wait for news about the town center. Watch Monarq's leasing signage, since a completed first phase means residents moving in on Germantown Pike this year. Watch for a public hearing notice on the former IKEA parcel, since that's the next approval PREIT needs before its own 275 to 300 units can move forward. And if you want to know when Adler's project is actually real and not just under contract, watch for a legal notice about a zoning hearing, since that's the step nothing has cleared yet.

The rendering of a two-level youth sports complex with an ice rink is a fun thing to imagine driving past. The apartment buildings already changing the skyline on Germantown Pike and Fountain Road are the part of this story you can actually see from the road today.

If you're weighing what any of this means for property values or timing a move in or around Plymouth Meeting, that's a longer conversation, and one worth having with someone who's been tracking these filings as closely as the zoning board has.
