Just because there is a plan of making a modernised building in place of the old structure, it is not a wise step to demolish the old one. Though it has happened in many places in our country that old buildings were demolished to pave ways for the new skyscrapers in which builder lobby also had interests but doing that everywhere is not a healthy option. In fact in many countries such buildings are converted in Museums or Libraries and the existing activities are shifted to a building elsewhere and that would be a better proposition.
Knowledge is power.
No life without Sun
If none of this exist one cannot agree with the destruction of an existing building.
Thoughts exchanged is knowledge gained.
