Urban design is the art of designing cities and focuses on relationships between buildings and public spaces. It considers the arrangement, appearance, and function of cities. Some key objectives of urban design include establishing character, continuity and enclosure, quality public spaces, ease of movement, legibility, adaptability, and diversity. Urban design is concerned with the user experience and how people connect to their surroundings, whereas urban planning focuses more on technical, political, and policy aspects like infrastructure and regulations. Gestalt psychology principles help designers create coherent designs and perceptions based on concepts like closure, proximity, similarity, figure/ground relationships, simplicity, symmetry, and continuity.
