A "high-rise" is a tall building, typically defined as having at least seven stories. These structures are commonly found in urban areas and are designed to maximize space in densely populated cities. High-rises often serve various purposes, including residential apartments, offices, hotels, and mixed-use developments. High-rise buildings are constructed using materials like concrete and steel, which provide the necessary strength and stability. They often feature elevators to facilitate movement between floors and may include amenities such as gyms, pools, and rooftop gardens. Examples of famous high-rises include the Burj Khalifa and the Empire State Building.
