A turnkey biotech hub arrives in Center City — and signals a broader momentum for Philadelphia’s life-science ecosystem
Philadelphia, PA — November 19, 2025 — Breakthrough Properties today announced a partnership with Eli Lilly and Company (“Lilly”) to establish Lilly Gateway Labs at Breakthrough at 2300 Market Street, offering a fully equipped, plug-and-play biotech workspace in the heart of Philadelphia’s life-science landscape.
The hub gives emerging biotech companies access to move-in-ready labs, fully furnished workspaces, and high-end amenities. Backed by the combined strengths of Lilly and Breakthrough, users will gain strategic engagement from Lilly scientists and executives as well as Breakthrough’s Scientific Advisory Board. Flexible lease terms, predictable service pricing and turnkey operations place the focus squarely on science — from day one.
Spanning 44,000 square feet across the first and second floors of the building, the facility includes cold storage, centrifuges, autoclave and other premium equipment. On-site staff provide concierge service, lab operations support and dock management; additional amenities at 2300 Market include an Alchemy Coffee café, conferencing space, a fitness centre and community programming.
Breakthrough Properties — a joint venture of Tishman Speyer and Bellco Capital — developed 2300 Market to be “the most comprehensive R&D ecosystem in the Philadelphia market.” Legend Biotech selected the eight-story, 225,000 square-foot building for its new cell-therapy research facility, anchoring the site as a multi-tenant innovation hub.
“Our partnership with Lilly Gateway Labs at 2300 Market will facilitate and accelerate the emergence of the next generation of great Philadelphia life science companies,” said Breakthrough Properties Chief Investment Officer Daniel D’Orazi. “By providing innovative scientists with comprehensive lab space, flexible growth opportunities and ready access to top minds and funding sources, Lilly Gateway Labs at Breakthrough will help reinforce Philadelphia as a hub for life changing discoveries.”
Designed by architecture firm KieranTimberlake, the building’s remaining space offers a lab-ready shell with robust infrastructure and highly flexible zones for a range of scientific uses. Located adjacent to the University of Pennsylvania, Drexel University and University City’s life-science cluster—and within a five-minute walk of 30th Street Station—the site combines academic connectivity with urban-core lifestyle.
A wider strategic backdrop
This announcement comes as Breakthrough Properties also revealed a major capital move: the firm has raised $430 million in its first closing of Growth Portfolio II, aimed at further scaling its life-science real-estate footprint across the U.S. and Europe. PR Newswire The raise reflects growing investor confidence in life-science real estate, and underscores how Breakthrough is ramping up to meet demand across major innovation clusters.
For Philadelphia, the Lilly–Breakthrough partnership and the wider capital raise add another signal that national life-science players see long-term value in the region’s talent density and rising infrastructure. While real-estate alone doesn’t create ecosystems, the coupling of major capital commitments with turnkey lab infrastructure often marks an inflection point: when higher-growth companies feel confident enough to locate — and when established biopharma sees the region as a growth node.
In my earlier piece on “leadership gravity,” I noted that when infrastructure and talent access begin to converge, regions begin to pull in the kind of companies and teams that tip the scale. The arrival of Lilly Gateway Labs at Breakthrough appears to be just that kind of moment for Philadelphia.
Looking ahead
Whether these moves will translate into faster company formation, increased hiring velocity, or stronger translational output remains to be seen. But the early indicators are positive: a major biopharma player and one of the leading real-estate platforms in life science committing to Center City; a sizeable capital raise backing further growth; and a location that offers operational readiness, academic adjacency and urban appeal.
As Philadelphia competes for national life-science attention, investments like these suggest the city is no longer simply keeping pace — it may be positioning to lead the next wave of life-science growth.
