Ancient India is seen today by its rich architecture, be it a fusion of ethnicity as seen in Fathepur shikhri or ages old Ajanta Elora or the Gharwal temples. If you would notice, one thing is common. These structures foster, sustainability based on the environment.
Even if it is for money, still we can mange to have projects that develops sustainable communities rather than a rich facade in the front and a claustrophobic behind. Even if Mumbai and Delhi is taken over by Builders, why is that not a situation in places like Singapore, Shanghai or Kualampur? With 40% of Indian revenue generated in Mumbai, why is there not a petronas tower or a structure developed in last 25 years that someone would admire. It has to do more with the will and determination of the architects and the builders, that we are lacking.
