Urban design

From Wikipedia, the free encyclopedia

Urban design concerns the arrangement, appearance and functionality of towns and cities. It is regarded variously as a disciplinary subset of urban planning, or of landscape architecture, or architecture.

Urban design theory deals primarily with the management of public space (i.e. the 'public environment', 'public realm' or 'public domain'), and the way these places are experienced and used. Public space includes the totality of spaces used freely on a day-to-day basis by the general public, such as streets, parks and public infrastructure. Some aspects of privately owned spaces, such as facades, also contribute to public space and are therefore also considered in Urban design theory. Important writers on, and advocates for, Urban design theory include Gordon Cullen, Jane Jacobs, William H. Whyte and Jan Gehl.

While the two fields are closely related, 'urban design' differs from 'urban planning' in its focus on physical improvement of the public environment, whereas the latter tends, in practice, to focus on the management of private development through planning schemes and other statutory development controls.

[edit] Urban Design Principles

Public spaces are frequently subject to overlapping management responsibilities of multiple public agencies or authorities and the interests of nearby property owners, as well as the requirements of multiple and sometimes competing users. The design, construction and management of public spaces therefore typically demands consultation and negotiation at a variety of levels, and urban designers rarely have the degree of artistic liberty or control sometimes offered in design professions such as architecture. It also typically requires interdisciplinary input with balanced representation of multiple fields including engineering, ecology, local history, and transport planning.

The scale and degree of detail considered varies depending on context and needs. It ranges from the layout of entire cities, as with l'Enfant's plan for Washington DC and Griffin and Mahony's plan for Canberra (although such opportunities are obviously rare), through 'managing the sense of a region' as described by Kevin Lynch, to the design of street furniture.

Urban design may encompass the preparation of design guidelines or even legislation to control development, advertising, etc. and in this sense overlaps with urban planning. It may encompass the design of particular spaces and structures and in this sense overlaps with architecture, landscape architecture and industrial design. It may also deal with ‘place management’ to guide and assist the use and maintenance of urban areas.

Much urban design work is undertaken by urban planners, landscape architects and architects but there are professionals who identify themselves specifically as urban designers and there are some university programs that offer degrees in urban design.

Urban design considers:

• Structure – How a place is put together and how its parts relate to each other

• Accessibility – Providing for ease, safety and choice when moving to and through places

• Legibility and wayfinding – Helping people to find their way around and understand how a place works

• Animation – Designing places to stimulate public activity

• Function and fit – Shaping places to support their varied intended uses

• Complementary mixed uses – Locating activities to allow constructive interaction between them

• Character and meaning – Recognizing and valuing the differences between one place and another

• Order and incident – Balancing consistency and variety in the urban environment in the interests of appreciating both

• Continuity and change – Locating people in time and place, including respect for heritage and support for contemporary culture

• Civil society – Making places where people are free to encounter each other as civic equals

[edit] History

Although contemporary professional use of the term dates from the mid-20th century, 'urban design' has been practiced throughout the history of human cities. Ancient examples of carefully planned and designed cities exist in Asia, India, Africa, Europe and the Americas, and are particularly well-known within Classical Chinese, Roman and Greek cultures. European Medieval cities are often regarded as examplars of undesigned or 'organic' city development, but there are clear examples of considered urban design in the Middle Ages (e.g. see David Friedman, Florentine New Towns: Urban Design in the Late Middle Ages, MIT 1988.)

A revival of urban design in Europe is associated with the Renaissance and, especially, the Age of Enlightenment. Spanish colonial cities were often planned, and in the Baroque period the design approaches developed in French formal gardens such as Versailles were extended into urban development and redevelopment. In this period, when modern professional specialisations did not exist, urban design was undertaken by people with skills in areas as diverse as sculpture, architecture, garden design, surveying, astronomy, and military engineering. In the 18th and 19th centuries, urban design was perhaps most closely linked with surveyors and architects.

Modern urban design can be considered as part of the wider discipline of Urban planning. Indeed, Urban planning began as a movement primarily occupied with matters of urban design. Works such as Camillo Sitte’s City Planning According to Artistic Principles (1889), and Robinson’s The Improvement of Cities and Towns (1901) and Modern Civic Art (1903), all primarily concern urban design as did the wider City Beautiful movement in general.

'Urban design' was first used as a distinctive term when Harvard University hosted a series of Urban Design Conferences from 1956 . These conferences provided a platform for the launching of Harvard's Urban Design program in 1959-60. The writings of Jane Jacobs, Kevin Lynch, Gordon Cullen and Christopher Alexander became authoritative works for the school of Urban Design.

Gordon Cullen's The Concise Townscape, first published in 1961, also had a great influence on many urban designers. Cullen examined the traditional artistic approach to city design of theorists such as Camillo Sitte, Barry Parker and Raymond Unwin. He created the concept of 'serial vision', defining the urban landscape as a series of related spaces.

Jane Jacobs' The Death and Life of Great American Cities: The Failure of Town Planning, published in 1961, was also a catalyst for interest in ideas of Urban design. She critiqued the Modernism of CIAM, and asserted that the publicly unowned spaces created by the 'city in the park' notion of Modernists was one of the main reasons for the rising crime rate. She argued instead for an 'eyes on the street' approach to town planning, and the resurrection of main public space precedents, such as streets and squares, in the design of cities.

Kevin Lynch's The Image of the City of 1961 was also seminal to the movement, particularly with regards to the concept of legibility, and the reduction of urban design theory to five basic elements - paths, districts, edges, nodes, landmarks. He also made popular the use of mental maps to understanding the city, rather than the two-dimensional physical master plans of the previous 50 years.

Other notable works include Rossi's Architecture of the City (1965), Venturi’s Learning from Las Vegas (1972), Colin Rowe's Collage City (1984), and Peter Calthorpe's The Next American Metropolis (1993). Rossi introduced the concepts of 'historicism' and 'collective memory' to urban design, and proposed a 'collage metaphor' to understand the collage of new and older forms within the same urban space. Calthorpe, on the other hand, developed a manifesto for sustainable urban living via medium density living, as well as a design manual for building new settlements in accordance with his concept of Transit Oriented Development (TOD). The popularity of these works resulted in terms such as 'historicism', 'sustainability', 'livability', 'aesthetic', 'high quality of urban components', etc. become everyday language in the field of Urban planning.....

[edit] Equality Issues in Urban Design

Disability

Until the 1970s, urban designers had taken little account of the needs of people with disabilities. At that time, disabled people began to form movements demanding recognition of their potential contribution if social obstacles were removed. Disabled people challenged the 'medical model' of disability which saw physical and mental problems as an individual 'tragedy' and people with disabilities as 'brave' for enduring them. They proposed instead a 'social model' which said that barriers to disabled people result from the design of the built environment and attitudes of able-bodied people. 'Access Groups' were established composed of people with disabilities who audited their local areas, checked planning applications and made representations for improvements. The new profession of 'access officer' was established around that time to produce guidelines based on the recommendations of access groups and to oversee adaptations to existing buildings as well as to check on the accessibility of new proposals. Many local authorities now employ access officers who are regulated by the Access Association. A new chapter of the Building Regulations (Part M) was introduced in 1992. Although it was beneficial to have legislation on this issue the requirements were fairly minimal but continue to be improved with ongoing amendments. The Disability Discrimination Act 1995 continues to raise awareness and enforce action on disability issues in the urban environment.

Gender

Little consideration was given to the issues of gender in the urban environment until the establishment of Women's Design Servicein 1987. A group of women architects and planners expressed concern that women’s issues were being largely ignored by planners, architects and urban designers. They explored a problem with the personal nature of design: designers tend to see themselves at the end of the pencil or mouse, and imagine themselves in the space they are designing. When the majority of clients, planners, landscape architects, architects, engineers and construction personnel are white, able-bodied men this tends to create an urban environment that reflects the needs and experiences of this particular group, excluding (deliberately or not) the needs of others. Illustrating this is Le Corbusier's famous call for buildings and urban environments to be designed to a human scale: the scale of his 'Modulor' was based on a six foot tall man.

Gender-aware urban design aims to cater to a human model that reflects both genders. Statistically women are smaller, have a shorter reach and are less physically strong than most men. The scale of stairs, door handles, chairs and many other designed elements tend to suit male ergonomics, while door closers match an able-bodied man's strength. Women have different physical functions; they require different toilet provision, areas for breast-feeding, accommodations for pregnancy, all of which have until recently been largely ignored by designers. Women's social position also has implications for urban design. Women still bear the major responsibility for caring for children and elderly relatives. They are still more likely to organise domestic responsibilities such as shopping and housework. Women have less access to use of a private car and are the greater users of buses. However public transport routes and timetables have been designed around the needs of commuters going into the centre at peak times and not around the needs of women delivering children to childcare, then visiting a relative, then going to work, then shopping, then collecting children again. Gender aware urban design seeks to acknowledge these issues in the way that our towns, cities, buildings, transport and open spaces are planned, designed and managed.

Ethnicity

Different cultures have different ideas about public space. For example, in Islam, a private space can be turned into a public space by the presence of a person of the opposite sex that could theoretically be a marriage partner.
