This is the Roundhouse at Hazelwood Green. The 19th Century roundhouse, once a home for machines, welcomes 21st Century researchers and entrepreneurs. Now as a technology accelerator, and co-working space for OneValley, this project is the first one tracked against Pittsburgh’s new resiliency standards. Before fast tracking the delivery

Of groundbreaking innovations, this 10-bay roundhouse originally serviced and turned train engines as part of the boarded up, 178 acre J&L Steel Mill.

While adapting to human scale, the design uses a light touch that celebrates the existing structure, preserving an important piece of Pittsburgh’s past. A cavernous two-story building, the abandoned roundhouse, dirtied by decades of industrial use, is partially built into the hillside. An addition of a mezzanine structure allocates more office space inside, aiding in the building’s shift to a human scale. The giant garage doors were replaced with windows, enabling occupants to appreciate the volume of this light-filled space and open views to the public space outside.

“A new public space uses native plants to integrate the site’s industrial remains - its turntable, the steel frame of an old shed - into the landscape of the Monongahela River.” GBBN
