  36. 36. RIBBON DEVELOPMENT• Ribbon development means building houses along the routes of communications radiating from a human settlement.• Such development generated great concern in the UK during the 1920s and 30s, as well as in numerous other countries.• Following the Industrial revolution, ribbon development became prevalent along railway lines - predominantly in the UK, Russia, and United States.• A good example of this was the deliberate promotion of Metroland along Londons Metropolitan railway.• Similar evidence can be found from Long Island (where Frederick W Dunton bought much real estate to encourage New Yorkers to settle along the Long Island Railroad lines), Boston and across the American mid- west• Ribbon development can also be compared with a linear village which is a village that grew along a transportation route, not as part of a citys expansion.
  37. 37. EKISTICS • Ekistics is the study of human settlement, which examines not only built forms, but also the interface of time, movements and systems in the built environment. • Doxiadis saw ekistics as an intellectual approach to balance the convergence of the past, present, and future in human settlements as well as a system for creatively coping with the growth of population, rapid change and the pressures of large- scale, high-density housing.

EKISTICS Ekistics Lograthamic Scale (ELS) MAN ELS consists of 15 Ekistic Units ranging ROOM from Man to Ecumenopolis DWELLING Classified under 4 major types NEIGHBOURHOOD Minor shells, or elementary units (man, room, house) TOWN Micro-settlements, the units smaller than, CITY or as small as, the traditional town where METROPOLIS people used to and still do achieve interconnection by walking CONURBATION Meso-settlements, between the traditional MEGALAPOLIS town and the conurbation within which one can commute daily URBAN REGION Macro-settlements, whose largest possible ECUMENAPOLIS expression is the Ecumenopolis,

  41. 41. BROAD ACRE CITY specific in his designation of the various elements. In a model representing four square miles, he proposed a main arterial adjoined to rectangular field used for agricultural purposes (vineyards and orchards).meandering stream in the southern portion. Zoning - by activity and function, and single- family home was the predominant building type. Large thoroughfares were intersected by large street at half-mile intervals.
  42. 42. BROAD ACRE CITY LAYOUT
  43. 43. BROAD ACRE CITY “organic buildings - designed by architecture”, to reflect the individuality of the population. This would eliminate the imitations which he felt were reflected in the World Expositions in Chicago (1893) and New York (1939-40). He further advocated the use of more modern material such asglass and steel which keeps the elements (of weather) out, but allows the outdoors in, putting man less separate from nature and eliminating what he likens to a fortification. buildings -groups of smaller units in a beautifully landscaped setting. He advocated the concept of mobile hotels and houseboats which promoted the freedom of movement aforementioned – the freedom to stay or the freedom to go.
