Tektronix was bursting at the seams in the Hawthorne plant. They were running three full shifts, there was inadequate parking for employees, and they simply needed a larger facility. The choice was made to move west, but not far enough to be out of the Bell Telephone System. Their choice for the location of the new Sunset plant was near the intersection of Highway 26 and Barnes Road. The first groups moved into the new facility early in 1951 but it was obvious by then that they needed even more room so work progressed on expansion and adding new buildings.
This 1953 photo shows the U-shaped expansion of the original building 81 and the new building 86 to the north.
This September of 1954 photo shows expansion of building 86 and increased build-up of the surrounding area. The building in the upper left corner is now the Beaverton site of the Department of Motor Vehicles.
This photo shows the expansion of both buildings and the expansion of the parking lot to the east. Quonset huts have been added inside the U and the front of building 81 expanded and the top floor of building 86 is increased to the East. The Quonset hut was two stories and contained a lot of storage.

Even though Tektronix had been expanding to the new Beaverton Campus in the late 1950s, the Sunset plant was fully occupied including even modular trailers until the move to Wilsonville in 1975.
