A mostly empty office park in Plymouth Meeting could be on its way out, with developer Sal Paone pitching a plan this week to swap cubicles for townhouses. The proposal would replace the Plymouth Ridge office park at 523–531 Plymouth Road with as many as 159 townhomes, putting one of the area’s larger recent residential conversions in front of township officials and neighbors.
The concept is scheduled for a presentation to Plymouth Township Council on Monday, followed by a conditional-use review at the township planning agency on Wednesday. Neither meeting is expected to deliver a final verdict, but both will give nearby homeowners and local officials an early, formal chance to react.
Sal Paone Builder is listed in the council’s June 1 workshop packet as the presenter for what the township labels the “Plymouth Wood Project,” an initial look at the townhouse layout shown in the township’s workshop packet. The item appears under “Presentation Items,” which signals council will listen and ask questions but not take final action at the workshop. It is an opening move in what could become a lengthy land-development review if the plan advances.
The site was rezoned last year to allow residential development, clearing the way for the townhouse concept, according to reporting by Montco.today. That coverage notes the proposal calls for demolishing four mostly vacant office buildings at the Plymouth Ridge Corporate Center, reusing a 37,000-square-foot structure for Mission Kids Child Advocacy Center and building two- and three-story townhomes across roughly 29 acres. The homes are aimed at move-up buyers and would include on-site parking, with the finer points to be hashed out in the formal land-development submission.
How the approval process works
The conditional-use application for 523–531 Plymouth Road is listed on the planning agency’s June 3 agenda, which will determine whether to recommend approval to council, according to the township’s meeting notice. The planning agenda lists “523‑531 Plymouth Rd, 159 Townhome Development for Conditional Approval.”
If the planning agency supports the application, council would then advertise a public hearing, take testimony at that hearing and later vote to approve or deny the conditional use. In other words, this week’s meetings are the start of the public process, not the finish line.
Neighbors' concerns and what to watch
During the 2025 rezoning debate, nearby residents raised alarms about density, traffic and potential strain on school capacity, according to MoreThanTheCurve. Traffic on Plymouth Road and Ridge Pike is a frequent sticking point in township conversations, and any land-development approval is expected to come with conditions tied to traffic and stormwater.
Expect detailed engineering reports and plenty of public comment to shape whether planners demand road upgrades, signal changes or off-site mitigation as part of any green light. The volume of cars and the way stormwater is handled could end up being as pivotal as the building designs themselves.
Next steps
Sal Paone is preparing full land-development plans; if the application clears both the planning agency and council reviews, Montco.today reported that construction could start as soon as late 2026 or early 2027, depending on permits and utility work. For now, the key dates to watch are this Wednesday’s planning agency meeting and any follow-up council notices, where officials and neighbors alike will be able to press for traffic studies, school-impact analysis and other potential conditions.
