ModelofTokyoBayPlan1960donebyKenzoTangeand hisassistantsinhisstudio.Kenzo Tange 1960 plan for Tokyo was proposed at a time when many cities in the industrial world were experiencing the height of urban sprawl.With a unique insight into the emerging characteristics of the contemporary city and an optimistic faith in the power of design.Tange attempted to impose a newphysical order on Tokyo,which would accommodate the citys continued expansion and internal regeneration.5.ThepostwarplanningofTokyohadsplittheidealandrealapart.Planner,architect,industrialiststarted

that Pilotis areas constitute spatial links between public and private areas.They are the areas in which the flow of traffic meets with stable architectural space.Core systems,on the other hand,link urban arteries with the buildings.Both cores and piles were integrated into a single system.8.DESIGNdivided the design into four major parts9.1)The connection between Tokyo and the proposed linear expansionThe first step in creating the civic axis is the construction of a cycle transportation system in a height of 40 meters above existing Tokyo that only touches the ground at points of interchanges.This system connects to all major highways and railroads.The plan shows the beautiful integration of the new transportation system into the existing one.10.2)The traffic circulation along the civic axisThe traffic circulation system is detached from the ground and suggests a strong separation between traffic and pedestrians.It is designed to carry up to 5,000,000 people daily.The grid on which the street system is based on consists of squares with side length of one kilometer.The system allows for a step by step expansion from Tokyo to the other side of Tokyo bay.Public buildings are located between the two parallel highways while residential areas are attach from the outside.11.3)The two main shapes of business buildingsThe business buildings are also detached from the ground and sit on so called cores that are organized on a grid consisting of squares with side length of 200 meters.The height of the cores ranges among 150 and 200 meters and leaves approximately 40 meters open space below the buildings.While one of the building types(A)relies strictly on the grid the other(B)has the shape of a spine pointing to public open spaces.12.The residential buildings(C)are attached to the civic axis through a perpendicular street system.Like leaves of a tree the residential area seems to grow away from the civic axis.The buildings reside on huge platforms on the water and propose the old relationship between the population of Tokyo and the sea.The buildings appear random in size and position but alike in shape.4)The perpendicular organic growth of the residential area13.THE CITY OF THEFUTURECould Tokyo Bay Host a Floating Eco-City in 30 Years?In the 2015 2025 Lloyds City Risk Index,Tokyo was identified as the 2nd most at risk city only behind Taipei.Hurricanes,earthquakes and flooding were the primary issues raised that put the metropolis at risk.14.Fifure 1.Land use diagram of the proposed next districtFaceted breakwater bars on the

Bay has experienced radical modification since the 16th century.16.Urban farming exists at multiple scales in the district,and the largest infrastructural rings collect saline bay water to grow algae,which can provide a clean fuel sourceFifure 3.Aeria veiw of roposed Next Tokyo district17.Fifure 4.Comparison of Kenzo Tanges Plan for Tokyo Bay 1960 and the Next Totyo 2045 Plan18.Fifure 5.Open-air sky decks at the top of the Sky Mile TowerThe plan calls for a 1600-meter tower(1 mile is 1609 meters),which would be twice as high as the worlds current tallest building.Theres always been a gradual increase in height for cities and Malott believes this trend will continue.19.
