Hazelwood Green
Open Minds, Open Spaces
The Vision
Hazelwood Green is rebuilding Pittsburgh’s riverfront as a beacon of innovation, creativity, and wellbeing—in ways that align with Pittsburgh and the surrounding communities. Here, people thrive, ideas take flight, and a historic industrial brownfield site is transforming into a sustainable, equitable, and inclusive new model for urban development.
What's Here
Hazelwood Green is situated on 178 acres along the Monongahela River adjacent to the Hot Metal Bridge in Pittsburgh’s Greater Hazelwood neighborhood. This vibrant hub sits at the intersection of the nearby Southside Flats, Pittsburgh Technology Center, South Oakland, and Greenfield with community events and programming, an abundance of green spaces, and miles of publicly accessible bike trails. In addition to the redevelopment of historic industrial structures—a former LTV mill and roundhouse—the site will soon include research and workspaces for Carnegie Mellon University and the University of Pittsburgh.
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.
Robotics Innovation Center
Breaking ground in 2023, Carnegie Mellon University's Robotics Innovation Center further enhances Pittsburgh's leadership in next-generation robotics and artificial intelligence. The 150,000 SF facility will accelerate research, integration, education, and commercialization in these groundbreaking fields.
BioForge
Breaking ground in 2023: The University of Pittsburgh’s BioForge, a 185,000 SF state-of-the-art biomanufacturing facility, will spark novel cell and gene treatments and therapies from concept to market. Equipped with advanced high-tech manufacturing, wet lab, and incubation spaces—and anchored by cutting-edge biomanufacturer ElevateBio—it's a catalyst for medical breakthroughs and patient care innovations.
Steelers Field
In partnership with the Pittsburgh Steelers and Robert 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. Steelers Field will also support coaches and offer certification opportunities, ultimately encouraging stronger and healthier players, teams, and communities. The project will break ground in 2024 and open in 2025.
Lytle Street Apartment Building
The first residential building at Hazelwood Green, being developed in partnership with Trek Development, is a new 50-unit apartment building right across the street from the Plaza Park with views of the former mill building. Our unique partnership with Pittsburgh Scholar House - a nonprofit focused on helping financially constrained 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 building’s first floor along Lytle Street will include a cafe, community room, fitness room, library, playroom, ample bike storage, and outdoor space. Leasing information will be made available closer to opening.
Green Space
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.

Meet the Team
Hazelwood Green's multidimensional development approach merges respect for its historical roots and its unique neighborhood context with the vibrancy of present-day culture. Through thoughtfulness and collaboration, it aims to establish new and lasting urban place-making models to craft a sustainable and inclusive future.
Community
Hazelwood Green’s unique position in the context of Pittsburgh’s urban landscape knits the historic Hazelwood neighborhood with groundbreaking research and innovation, marking a new chapter of thoughtful, inclusive economic development.
Formerly the home of Jones & Laughlin Steel, Hazelwood Green’s roots are in land that once housed the steel mills that powered the nation and shaped the economies of Western Pennsylvania and the Hazelwood community. Today, that land has been environmentally transformed. The site’s vibrant Plaza, trail and green spaces are open to all, and a new future is unfolding -- one that is grounded in opportunity and a commitment to equitable, sustainable growth.
Hazelwood Green flows seamlessly into the surrounding neighborhood, where two decades of philanthropic investment are reviving the once-bustling Second Avenue main street, preserving historically significant buildings, strengthening local businesses, enhancing amenities and services, and fostering economic diversity.
