A tall building, often referred to as a skyscraper, is a structure that significantly exceeds the height of surrounding buildings. These buildings typically have multiple floors and are designed for various uses, including residential, commercial, and office spaces. The height of a tall building can vary, but it generally starts at around 150 feet (45 meters) or more. Tall buildings are constructed using materials like steel and concrete, which provide strength and stability. They often feature elevators to facilitate movement between floors and may include amenities such as parking, restaurants, and observation decks. Notable examples of tall buildings include the Burj Khalifa in Dubai and the Empire State Building in New York City.
