The Qatar National Convention Center was designed by the renowned Japanese architect Arata Isozaki with RHWL Architects. The facade resembles two intertwined Sidra trees reaching up to support the exterior canopy. In the desert, the tree is a beacon of learning and comfort, as well as a haven for poets and scholars, and the Sidra tree is a symbol particularly for perseverance and determination. The largest convention center in the Middle East, the QNCC features a 4,000-seat conference hall, a 2,300-seat theater, three auditoria, and 52 flexible meeting rooms. It also has nine halls that total 40,000 square meters of exhibition space, and can seat 10,000 for a conference or banquet. It was built to LEED Gold certification standards, and is designed to operate efficiently with water conservation and energy-efficient fixtures.
