Question: How many feet tall is the KCTV-Tower? Passage:The Nelson-Atkins Museum opened its Euro-Style Bloch addition in 2007, and the Safdie-designed Kauffman Center for the Performing Arts opened in 2011. The Power and Light Building is influenced by the Art Deco style and sports a glowing sky beacon. The new world headquarters of H&R Block is a 20-story all-glass oval bathed in a soft green light. The four industrial artworks atop the support towers of the Kansas City Convention Center (Bartle Hall) were once the subject of ridicule, but now define the night skyline near the new Sprint Center along with One Kansas City Place (Missouri's tallest office tower), the KCTV-Tower (Missouri's tallest freestanding structure) and the Liberty Memorial, a World War I memorial and museum that flaunts simulated flames and smoke billowing into the night skyline. It was designated as the National World War I Museum and Memorial in 2004 by the United States Congress. Kansas City is home to significant national and international architecture firms including ACI Boland, BNIM, 360 Architecture, HNTB, Populous. Frank Lloyd Wright designed two private residences and Community Christian Church there.
