High-rises are tall buildings that typically have multiple floors, often exceeding six stories. They are commonly used for residential, commercial, or mixed-use purposes. High-rises are designed to maximize space in urban areas where land is limited, allowing for more people or businesses to occupy a smaller footprint. These buildings often feature elevators to transport people between floors and may include amenities such as gyms, pools, and rooftop gardens. High-rises are constructed using materials like steel and concrete, which provide the necessary strength and stability to support their height. Examples of famous high-rises include the Burj Khalifa and the Empire State Building.
