Tall buildings, often referred to as skyscrapers, are structures that reach significant heights, typically over 150 meters (492 feet). They are designed to maximize space in urban areas where land is limited. These buildings often house offices, apartments, hotels, and retail spaces, contributing to the skyline of cities like New York City and Dubai. The construction of tall buildings involves advanced engineering techniques and materials, such as steel and reinforced concrete. Architects and engineers work together to ensure stability and safety, considering factors like wind resistance and seismic activity. Iconic examples include the Burj Khalifa and the Empire State Building.
