Roundhouse at Hazelwood Green

Allegheny County, Pennsylvania

Once a home for machines, the 19th Century roundhouse at Hazelwood Green welcomes 21st Century researchers and entrepreneurs.

Project Description

The Roundhouse at Hazelwood Green involves the adaptive reuse of a formerly shuttered 10-bay roundhouse built in the late 1880s, on the 178-acre J&L Steel mill site.

Now a co-working space for the technology accelerator OneValley, the Roundhouse is the home of groundbreaking innovations and the first project tracked against Pittsburgh’s new resiliency standards. Working with design lead GBBN, Buro Happold provided MEP engineering, IT/AV/security engineering, and energy modelling services to the project. To preserve this important piece of Pittsburgh’s past, the design uses a light touch approach that celebrates the existing structure while adapting it to a human scale. The team employed high performance strategies throughout the project, including incorporating energy efficient systems for heating and cooling, Variable Refrigerant Flow (VRF) systems, high efficiency LED lighting, flexibility of spaces within the building, and all electric design to meet the site’s future goals of carbon neutrality.
