New Layers.Identical in shape and dimensions to its stone counterpart, the new glass box rests atop the original structure. A second glass volume extends down the back of the building and includes brand-new retail access from the street level. Designed to accommodate a wide range of uses, the addition includes tenant terraces and a roof deck that further connects people with the city. It was a challenging but fun job, Selig says. Erik and his team are superior. We came together to do a great building and we did just that.Perkins&Will also quantified how much carbon is already embodied in the original building and repurposed original materials wherever possible to lower its footprint. A life-cycle analysis, conducted at the end of construction, found that preserving existing building materials saved approximately 50% of the building’s global warming contribution compared with projects of similar size and complexity.Respecting History.On top of constructing the addition, Selig updated the original footprint so that it could survive another century. The 1913 building had been renovated only once in its lifetime, in 1950, but otherwise left untouched. In 2008, it became vacant for nearly a decade before its modernization. To honor its history, stone and brass finishes from the original renovation were salvaged and repurposed. Two new elevators were added, and the existing ones were refurbished and widened.Text description provided by the architects.Built in 1913,Seattle’s Federal Reserve Bank building acts as a window to the past in a city typically defined by its progressive, forward-thinking culture. When property developer Martin Selig bought the property at a government auction in 2014, he aimed to update it for contemporary use while preserving those historical links. The Seattle studio of Perkins&Will was commissioned to revitalize the iconic stone box with a modern addition and new amenities, a particularly difficult mission given the property’s landmark status.Seattle’s Forward-Thinking Culture.Seattlemay be considered a newer city, but its population is adamant about preserving its existing history. There’s this sort of brinkmanship negotiation between well-meaning preservationists and the more ambitious developers to find some common ground,” Mott says. “On this project, however, we wanted to figure out a way to preserve what’s important while weaving in modern resilience and sustainability solutions.” For example, the bank’s exterior limestone cladding was removed, treated, and re-installed to ensure the building was up to today’s earthquake codes. “It’s the original material and looks the same,” he explains. “But it’s safer.The design for the project had to be sensitive to specific requirements on both the federal and state levels, which don’t always align with each other. Perkins&Will worked to find the right balance between old and new. The renovation included a glass addition that appears to float over the existing historic building. The cantilevered relief between the two is really eye-catching,” says Erik Mott, Design Co-Director of Perkins&Will’sSeattlestudio. “But the whole building has a real presence to it.
