The Systel Building in downtown Fayetteville, with its looming aluminum-and-glass facade, has been undergoing extensive renovations since August 2018. Now, it has a new anchor tenant. Raleigh-headquartered Dogwood State Bank has moved into the first floor of the downtown fixture, which ranks as the city center’s tallest. Listed at 168 feet high, the 11-story building dates to 1973 when it was completed at a cost of $3 million, online sources say.
