NYC - TriBeCa: AT&T Long Lines Building The AT&T Long Lines Building, at 33 Thomas Street, was built in 1974 to the design of John Carl Warnecke & Associates. The 551-foot, 29-story tall almost "windowless" tower--an extreme example of the Brutalist architectural style--was designed to provide security and protection of the expensive equipment houses inside. Another bi-product of the technical nature of its occupant, each floor is built 18 feet high, nearly double the normal office building. The exterior walls are pink-colored Swedish granite-faced precast concrete panels, and the building has six large protrusions which rise to the top. / VFL.Ru
