Whether it’s big box chain stores or anonymous manufacturing facilities, wide, flat-faced buildings are a common sight on the route into Rochester, Minnesota, from the north. About five miles from downtown, the IBM Manufacturing & Training Facility has a similar boxy massing to other buildings on the street but has a distinctive blue facade pattern. From the air, the vast scale of this building can start to be understood – in fact, when viewed from above, it resembles a computer chip. IBM Rochester is still the largest IBM facility under one roof, enclosing 3.6 million square-feet on 400 acres. In this city, IBM’s frequent moniker “Big Blue” applies to both the company and the building. Commissioned in 1956 and designed by Eero Saarinen & Associates, the opening of the building in 1958 marks a key moment in IBM’s design legacy and Minnesota’s computing industry.
