DESCRIPTION

Urban design on Indean cities, calculating and analyzing urban growth and effects.

TRANSCRIPT

  • *

  • Urban design-All planning aspects with reference to all types of human activities in and around built environment and also natural environment.InterdisciplinaryBetween Architecture and town/urban planningUrban design is the process of giving form, shape, and character to groups of buildings, to whole neighborhoods, and the city. Involves the arrangement and design of buildings, public spaces, transport systems, services, and amenities.Involve design of cities, neighborhood, satellite cities, ecology, environmental design, conservation of heritage, connectivity, street pattern, etc.blends architecture, landscape architecture, and city planning together to make urban areas functional and attractive.

    *Definat ion

  • *Connections-people and places, movement and urban form, nature and the built fabric.

    Concepts-Public realm, Place making, urban space, plazas, squares,image making, public vistas, landmarks, focal pointsSafety-connectivity

    Scale-Regional level-city and townNeighborhood level- district and corridorBlock level- street and building

  • Urban design-Includes

    Connectivity

    Mixed uses-commercial, educational etc.

  • Landscape

  • Aims that

    - To make the city humaneTo relate urban forms to natural settingsTo weave new centers into the urban fabricTo complement the monumental with the mundaneTo complement urbane with the natureTo create key focal sites to make the city a harbor of diversity

    Principles of scale- of masses, of spaces, of activity areasUrban design-*Quality of Life Taken together these add up to a high quality of life well worth living, and create places that enrich, uplift, and inspire the human spirit.

  • Scale in Urban design*To make the city humaneTo relate urban forms to natural settings

  • *To complement the monumental with the mundane

    To complement urbane with the natureScale in Urban design

  • *To create key focal sitesScale in Urban design

  • *Masses Buildings are the most pronounced elements of urban design - they shape and articulate space by forming the street walls of the city.SpacesGreat public spaces are the living room of the city - the place where people come together to enjoy the city and each other.

    ActivitiesStreets, Markets, plazas and squares, to small, local neighborhood parks. Principles of scale- of masses, of spaces, of activity areasThey form the stage and backdrop to the drama of life.

  • *Conceptualizing factors: urban spaces, urban mass, circulation patterns, urban scale , the process of urban growth and change. The components of urban formUrban mass- built form, heritage structures, monuments, landmarksUrban Spaces- streets, plaza, squares, nodes, open spaces, parks, transportation etc.Circulation pattern- organic, ring, grid, rail, roads, connections, etc.Public RealmOpen to allGives characterCreates imageAllows interactionSafety ValuesPlace makingUrban growth- sprawl, area growth, density, texture, skyscape.Connections

  • *The arrangements of the physical form of the city is the objective of urban design.Thus the proper application of the elements of urban design may be thought of as principles:-the proper array of urban masses-the proper deployment of urban spaces-the functional deployment and mixture of urban activities and-the functional arrangement of patterns of movementThe physical city, is a system of activity areas, spaces, masses and circulation systems which are constantly undergoing change.

  • Brazilian capital Brasilia was planned and developed in 1956 with Lcio Costa as the principal urban planner and Oscar Niemeyer as the principal architect. Viewed from above, the main portion of the city resembles an airplane or a butterflyWashington, D.C., formally the District of Columbia, is the capital of the United States. On July 16, 1790, the Residence Act approved the creation of a capital district located along the Potomac River on the country's East CoastCanberra from space: Australia's capital is an entirely plannedcity outside of any stateLa Plata, Argentina, is designed based on a rationalist conception of urban centers. The city has the shape of a square with a central park and two main diagonal avenues, north-south and east-west, copied in a self-similar manner in small blocks of six by six blocks in length. Every six blocks, one finds a small park or squareNamed in honour of Adelaide of Saxe-Meiningen, queen consort to King William IV, Adelaide was founded in 1836 as the planned capital for a freely settled British province in Australia.

    Book- Urban space-includes a study of urban types-especially of sections-350 examples in plan of urban spaces in different cities of Europe.-defines concepts of urban space as open, comprising all types of spaces, between buildings in towns and localities, ranging from courtyard within individual building to wide open spaces(including landscape, water bodies, mountain slopes, group of buildings).Analysis followed by history-Le CorbusierReads the city as formed of urban spaces- like streets, open spaces, squares, form of these may be pure geometric , which may be twisted, divided, added, penetrated, overlapped.These streets, squares are lined by buildings, framed by facades.-includes faade details-the physical form is by relationships between streets and open spaces , the elevations sections which enclose them.

  • In the current study

    The reference to political field is to the state, Central government, its institutions, policies and planning strategies, their concepts and ideologies like Socialism, Capitalism, communalism, Fascism, Globalisation, Racism, etc. And Their effects on Urban development through effects on markets, housing typology, land use pattern, area density, urban sprawl, new building typology etc.

    QuestionsThe question is what the all encompassing Political ideologies and their decisions in the form of policies and strategies trigger effects on urban development , not whether certain Architecture is aligned to the right/ left/ particular party or leaders or power.

    The question is what are the reflections of Political ideologies on the growth of the cities?

    The idea is to discover possibilities of interactions between the two, but not to give firm definitions, or apt or utopian ideologies for development of Architecture and growth of cities.

  • Literature review- current studies

    Urban developmentActivist and Architect P.K.Das suggests that a city can truly be developed through larger public participation and the engagement of peoples organization in the development process. Democracy and democratic movements are the means to achieve this objective. Thus housing movements must integrate with it for enabling social changes and for achieving development justice.

    Mhatre P Relaxing Regulations to Support the Growth and Development of Industries Case for Bangalore, India argues that the role of the government in Bangalore has succeeded in generating economic growth but not as much economic development. Other regions in India have attempted to duplicate the Silicon Valley model without much success because they lack the necessary and required qualities that technology companies look for like the existing infrastructure, high quality academic institutions and skilled manpower.

    McCann. E in Framing Space and Time in The City: Urban Policy and The Politics Of Spatial and Temporal Scale Journal of Urban Affairs, Vol 25,No 2, pgs 159-178. argues that Urban Politics is frequently characterised by Political strategies that frame reality in terms of scale (spatial and temporal scale).

  • Literature review- issues identified (2013)

    Socialism and its effectsNeo- Liberalism and its effects1970s, 1980sSocialism prioritized notion of equality therefore Distribution, use of social funds, public participation, inclusion concepts etc. Social rights included The right to be informed, The right to participate in decision making, The right to minimal living condition with human dignity, property rights etc. Policies and strategies developed includedStrengthen the role of the state, Provision and compensation for housing for all Broaden Tax base, raise marginal tax ratesProvide basic services (water, drainage, sewerage, roads) to urban areas.Provide for loans, grants, subsidies for agriculture sectorEncourage small scale industries, business, co-operatives1990s focused on Liberalization.Liberalism is an economic ideology that tends to make a self- regulating market.

    Policies initiated to make Indian cities more competitive in global circuit triggered dynamism in urban context, bringing large scale Public Private investments in construction Industry and infrastructure development sector. These included construction of public amenities like roads, flyovers, bridges public spaces, metros etc.
