INTRODUCTION The CBD or Central Business District is the focal point of a city. It is the commercial, office, retail, and cultural center of the city and usually is the center point for transportation networks. . It maintains a special cultural status as historic centre of the city as well as serving as a community centre for the surrounding region. It also maintains a pedestrian oriented character. The CBD developed as the market square in ancient cities. On market days, farmers, merchants and consumers would gather in the center of the city to exchange, buy, and sell goods. This ancient market is the forerunner to the CBD. As cities grew and developed, CBDs became fixed location where retail and commerce took place. The CBD is often near a major transportation route that provided the site for the city's location, such as a river, railroad, or highway. HISTORIC BACKGROUND || CENTRAL BUISNESS DISTRICT LIBRARY STUDY
  10. 10. 10 OBJECTIVES • The entire complex shall be designed with proper orientation and maximum wind movement. Building may be oriented along NW – SE orientation. • Development of open spaces, nodes and transition spaces between main building and approach areas. • Ensuring proper connection between public areas, semi public areas and services. • While formal and informal areas shall be well connected, a sense of segregation should be ensured as well. • To create streets which are safe and attractive to pedestrians. • To provide activity and interest along the street. SITE PLANNING The allocation of spaces for these and possibly others users should be guided by certain planning principles in order to attain the highest feasible productivity of the land over an extended period of time 1. Safeguard surrounding areas against the blind 2. Expose retail facilities to maximum foot traffic 3. Separate various mechanized traffic type from one another 4. Create a maximum of comfort for the shoppers and merchants 5. Achieve order, unity and beauty. N The shop units and the plazas should be north facing to avoid the glare Pedestrian friendly complex Barrier free environment || CENTRAL BUISNESS DISTRICT LIBRARY STUDY

  12. 12. 12 POSSIBLE SECTIONS No sense of enclosure Good sense of enclosure (45angle) Proper sense of enclosure No sense of enclosure (15angle) || CENTRAL BUISNESS DISTRICT LIBRARY STUDY When building height is equal to the street height, a sense of enclosure is generated. In this case, building façade is more detailed When building height is equal to the one third of street width, the skyline dominates over the building When building height is equal to one fourth times of street width, the sense of enclosure is completely lost. POSSIBLE LAYOUTS This layout comprises of a separate area for pedestrian in the form of pedestrian mall This layout differs from the first option by the introduction of activity areas like museum or library. OPTION 1 OPTION 2 OPTION 3 central parking with peripheral buildings and service roads. All blocks enclose a common open space. It leads to the creation of variety of spaces approach with one court & two magnets placed in diagonal manner. It is the simplest of all layouts. The centre is approached through linear connectivity. OPTION 4
  13. 13. 13 Parking requirement/E.C.S 1)0° - parallel to road. Entry and exit to parking bay difficult. Suitable for narrow roads. 2) 30°- angle to access road. Easy entry to parking bay and exit. Uses a large area. 3) 45°- angle to access road. Good entry to parking bay and exit. Relatively small parking space. 4) 60°- angle to access road. Relatively good entry and exit to parking bay; small parking space. Arrangement often used. 5) Right angles to road (parking spaces 2.50 m wide). Sharp turn needed for entry and exit. 6) Right angles to road (parking spaces 2.30 m wide). Small area needed for parking space. Ideal for compact parking layouts, used frequently.

  40. 40. 40 STRENGTH • Nehru place is located on the Outer Ring Road so it can be easily accessible by the other parts of the Delhi. • Being an IT Hub, the market caters more to the people of age group 25-35 years because of there shops or job or shopping, etc. • Nehru Place is designed in such a way that large open spaces are there between the towers, in form of courtyards and parking. Due to long courtyard connectivity fresh air enter these corridors with a thrust. • Parking are designed near to the Towers which makes it easy for the crowd and the employees and also to the transporters. • Office blocks are on the second floor which are totally segregated from the loud and the crowd. WEAKNESS Since it was not planned to accommodate these numbers, the result is congestion, lack of sanitation, and a degenerating infrastructure in and around the areas surrounding Nehru Place. The market is not so User Friendly, i.e. can’t be easily accessed by handicaps and senior citizens find it difficult to climb the stairs Lack of cultural and recreational spaces Make highly extensive shopping plaza. Heavy and rigid concrete boxes and linear Planning. The centre has not been able to attract local shoppers, since it is not located on an existing commercial spine The centre stays dead in the night, save some homeless laborers who find the shelter of the corridors adequate to pitch in at night.
