Urban Design Overview

Definitions of Urban Design

  • Intermediary discipline between planning and architecture

  • Art of shaping cities and towns, connecting people and places

  • Framework organizing streets, squares, and blocks

  • Integrates architecture, landscape, and city planning for functionality and attractiveness

  • Aims to create sustainable spaces improving quality of life

Key Aspects of Urban Design

  • Encompasses elements such as public space, infrastructure, transportation, landscapes

  • Requires public participation for project success

  • Collaboration with clients, landscape architects, civil engineers

Historical Background

  • Term 'urban design' popularized in late 1950s in North America

  • Practice dates back throughout history

Objectives of Urban Design

  • Character: Unique identity through improved townscape

  • Continuity and Enclosure: Distinct public/private spaces

  • Quality of Public Realm: Attractive, functional outdoor areas for all

  • Ease of Movement: Ensure accessibility and connect places

  • Legibility: Recognizable routes and landmarks

  • Adaptability: Responsive designs to changes in society

  • Diversity: Varied developments meeting local needs

  • Sustainability: Ecologically friendly urban environments

Terminology

  • Urban Form: Physical layout and extent of the city

  • Urban Fabric: Physical aspects emphasizing building types and spaces

Theories of Urban Design

/

Three Main Approaches:

  1. Figure-Ground Theory

    • Focuses on land coverage relationship of buildings to open spaces

    • Analyzes textures and patterns of urban fabric

    • Illustrated by Nolli's 1748 map of Rome

  2. Linkage Theory

    • Centers on connections formed by streets, paths, and open spaces

    • Considers circulation dynamics as generators of urban form

    • Identifies three spatial linkage types: compositional, mega, and group forms

  3. Place Theory

    • Integrates human needs and context in design

    • Recognizes the impact of historic and cultural values

    • Influenced by designers like Ralph Erskine, Leon Krier, and Kevin Lynch

Conclusion

  • Best urban designs integrate all three theories, addressing structure, linkage, and human needs in response to various environmental elements.
