What's Here
At Hazelwood Green, every part of the site works together to support how people move through their day. Spanning 178 acres along the Monongahela River, restored historic structures and new development come together to form a connected district shaped by innovation, community, and access to nature.
From research and advanced manufacturing to housing, parks, and public programming, each destination plays a role in creating a place that feels open, active, and ready for what’s next. Positioned between downtown, the South Side, and Oakland’s university center, Hazelwood Green is part of a broader ecosystem where research, culture, and industry come together to support new ideas, growing companies, and lasting opportunity.
Roundhouse
Built in 1887, a 10-bay roundhouse and turntable has been transformed into an innovation hub led by OneValley, a Silicon Valley–based platform connecting and supporting entrepreneurs, startups, and organizations around the world. The workspaces feature high ceilings, ample natural light, and green space connecting the building with the project beyond. This structure links Hazelwood Green's industrial past with Pittsburgh’s start-up ecosystem.

HG Community Field
In partnership with the Pittsburgh Steelers and Richard K Mellon Foundation, Tishman Speyer will be bringing a multi-sport facility to support the region’s youth through active recreation, skills-building, and wellness to Hazelwood Green. The facility will be utilized year-round for Steelers-sponsored programming, sports, and community organization activities – all of which emphasize health, resilience, and leadership development. Hazelwood Stadium will also support coaches and offer certification opportunities, ultimately encouraging stronger and healthier players, teams, and communities.
Woodlawn Lofts
The first residential development at Hazelwood Green, being developed in partnership with Trek Development and Module, is a new 125-unit apartment building right across the street from the Woodlawn Park with views of the former mill building. A unique partnership with Pittsburgh Scholar House - a nonprofit focused on helping single parents working their way through college - will allow select residents to access an array of services in the building. Designed by Perfido Weiskopf Wagstaff + Goettel, the buildings along Lytle and Blair Streets will include cafes, community rooms, fitness rooms, a library, playroom, ample bike storage, and outdoor space. Leasing information will be made available closer to opening.
Woodlawn Park
The two-acre park at Hazelwood Green offers a mix of natural and recreational spaces, including a tiered water feature, rain gardens, pollinator gardens, lawns, trees, native vegetation, and hardscaped surfaces that accommodate a range of public events, with more recreational spaces rolling out over the next few years. Hazelwood Trail spans the entire site, connecting with the Three Rivers Heritage Trail at Hot Metal Bridge toward Second Avenue with plans to connect through Duck Hollow to the Carrie Furnace trail in the future. On-site programming is executed by Hazelwood Local, an initiative managed by urban design and placemaking firm Street Plans, and is open to all.
Mill 19
Mill 19 is a three-building research and development hub for advanced manufacturing born from the remains of the LTV Coke Works steel mill. The former mill’s metal walls and roof have been stripped away to reveal its underlying steel superstructure and three new LEED-Gold buildings have been constructed within it. Some of the most innovative institutions and companies in Pittsburgh call Mill 19 home, including the Advanced Robotics for Manufacturing Institute and Manufacturing Futures Initiative (affiliates of Carnegie Mellon University), autonomous vehicle company Motional, Catalyst Connection, and YKK AP.
