Well burj khalifa is really a good architecture.with the development of science and technology people are building 165 floor house within which 475 lavish flats with malls,mosque etc etc.really a wonderful architecture.somebody told that india will need to travel 2100 to make such a huge building,i just want to tell him that making tall buildings with huge numbr of floos does'nt represents that good architectorial skills.India already possess some beautiful architecture,like taj mahal,victoria memorial,mysore palace etc etc which if saudis try would never can make like the same one but if India tries it can make the world's tallest building but that would be of no use and would'nt give nothing to the poor people.the thing that would'nt help the citizens of india.
