In 2018, Karlin purchased the research and development campus and buildings from GlaxoSmithKline and commenced Parmer RTP, a repositioning of the site and leasing of the buildings. McDonald York was selected as the general contractor to construct a suite of world-class amenities on the 550-acre campus including a brand new outdoor amphitheater, championship-level tennis courts, outdoor gathering areas, and a grand lawn with corn hole courts, putting greens, and volleyball courts. In addition, McDonald York constructed a parking deck adding over 700 spaces, surface parking, and numerous high-quality, state-of-the-art office and laboratory spaces throughout the 1.7M square-foot campus.
