BIG, West 8 and Atelier Ten have revealed their masterplan design for Pittsburgh's Lower Hill district, just outside the city's downtown region. Located on the former site of Pittsburgh's Civic Arena, which was demolished in 2012 and has since left a significant hole in the city's fabric, the design will bring 1,200 residences and over 1 million square feet of retail space to the area, while reconnecting the wider Hill District with the downtown core by reinstating the city's road grid, overlaid with a series of pedestrian footpaths, public plazas and green spaces.
