The last building used for making cigarettes downtown was Building No. 12 across Second Street from the Building 256 complex, which Forsyth County bought when manufacturing ended there in 1990; finished in 1916, it was to be renovated for county offices after an announcement in 1999. Building 60 was built in 1923 and later renovated. Three buildings which were part of the "90 series" on Vine Street were later renovated; the one at 525 Vine was built in 1926, while Buildings 90-3 and 90-1A at 635 Vine, used for tobacco processing, were built in the early 1960s. Building 91, a machine shop built in 1937, was later renovated and became part of the research park. Bailey Power Plant, a coal-fired plant built in 1947, included Buildings 23-1, 23-2 and the Morris Building, and was used until 1997 and later became part of the research park. The company's headquarters were located in the Reynolds Building in Winston-Salem for more than 50 years. Built in 1929, the 21-story building was designed by the same architects (Shreve & Lamb) who later designed the Empire State Building in New York City. The first R.J. Reynolds buildings on present-day Reynolds Boulevard were the three-story leaf buildings, the 2-1 building built in 1937 and the 2-2 building in 1955. These were named to the National Register of Historic Places in October 2017, and in October 2019 C.A. Harrison Cos. LLC, developer of Plant 64, announced the buildings would be renovated for loft apartments. Built in 1961 at a cost of $32 million ($254 million in 2015 dollars), the Whitaker Park plant had 790,300 square feet of manufacturing space and was considered "the world's largest and most modern cigarette-manufacturing plant". It was announced in May 2010 that cigarette manufacturing would cease at Whitaker Park; by mid-2011, this had been done. Manufacturing formerly performed at the Whitaker Park plant was consolidated in the more-modern Tobaccoville plant. On January 7, 2015, Reynolds announced that Whitaker Park was being donated to Whitaker Park Development Authority Inc., started in April 2011 by Winston-Salem Business Inc., the Winston-Salem Alliance and Wake Forest University. As of October 2019, Hanesbrands had taken over space in the 601-11 building as a distribution center, and Cook Medical had plans to move into 850,000 square feet of the plant by 2022. In September 1977, R.J. Reynolds Industries moved the first of 1200 headquarters employees into the not-yet-completed, $40 million, 519,000-square-foot glass and steel World Headquarters Building being built across Reynolds Boulevard from the Whitaker Park plant.
