Mill 19 is a living emblem of Pittsburgh’s transformation from its industrial steel-making past to a future of sustainable advanced manufacturing. In a bold approach to adaptive reuse, the design viscerally interweaves new space for the city’s robotics industry within the industrial ruins of a decommissioned steel rolling mill. A post-industrial promenade welcomes the public through a linked series of compelling exterior experiences framed between the monumental 1,360 foot-long existing steel superstructure and three multi-tenant tech buildings sited within. The Mill 19 project accomplishes impressive levels of experiential, sustainable performance and public access within the financial constraints of a speculative core and shell commercial development.
