Positioned at the intersection of Liberty Avenue, Sixth Street and Market Street, 600 Liberty Avenue is poised to become a landmark in Pittsburgh’s downtown. Developed by PNC Realty Services, the renovation of the existing building takes full advantage of its prominent location to dramatically transform its image and increase its usability for an office, retail or event use. 600 Liberty Avenue is an underutilized four story masonry building located adjacent to Pittsburgh’s thriving Cultural District and PNC’s corporate headquarters. As a result of the building’s prime location, it has long been used as advertising space with two billboards affixed to the façade and roof. PNC sought to buy and renovate the building not only for the enhancement of PNC’s campus but for the Pittsburgh community as well. As envisoned by EDGE studio, the building will have a canted green roof, and new facades that will transform it to be a translucent glass form contrasted with rich naturally oxidized zinc panels by day and a glowing lantern by night. Designed with sustainable strategies as a priority, the building continues PNC’s legacy of supporting sustainable environments and lifestyles. At the street level, translucent storefront is used to create a direct connection to the interior of the gallery space. Above the street level, a channel glass projection wraps each façade with portions cut away to allow for views out from the interior. By cladding the front façade almost entirely in glass, the building has the ability to interact with pedestrian and vehicular traffic throughout the day and possibly even more at night. At night LED light fixtures will graze the channel glass turning the building into a ‘glowing beacon’ that can be seen from 6th Street Bridge, Market Square and along Liberty Avenue. During the evening, the steel structure which originally provided support for billboards, will be celebrated as it casts shadows and silhouettes onto the transparent glass and channel glass. EDGE also saw an opportunity to ‘extend’ Triangle Park to 600 Liberty Avenue, by allowing the natural colored zinc panels to dissolve to green zinc as they turn the corner to the west façade. The green zinc panels climb the façade to a sloped green roof which will be visible from Triangle Park.The existing building presented a number of challenges throughout the design process including available usable area and physical shape of the building, but most prominent were a number of code related issues. Because the building has a small footprint (approx. 900sf) adding an elevator and two exit stairs rendered the remaining area as unusable. The solution was to reduce the existing four story building to two stories with a single exit stair. EDGE accomplished this by modifying the existing second floor into a mezzanine overlooking the first floor and eliminating the fourth floor by hinging the roof toward PNC’s Triangle Park. Not only did these modifications generate a building that is code compliant but it created expansive volumes of interior space with floor to ceiling heights reaching 23’-0” in the main space.
