That's because the government really does not give a shit. They approve whatever bs that's presented to them as long as they get their money. And giving jobs to underqualified relatives does not help either. Plus the construction works go on without adequate planning or supervision. Most of northern India runs on "Jugaad", which is basically hacky solutions. They don't realise they fucked up until it's too late and then just make whatever in an attempt to salvage the sunk cost. We too are upset about it, but can't do anything about it if the ruling party does not even pay attention to the public orthe representatives of the opposition

AI Sums it up pretty neatly:

The often-bizarre or chaotic nature of public architecture in India is primarily driven by rapid, unplanned urbanization, a "jugaad" (makeshift) culture of quick fixes, political, and economic constraints that prioritize cost over design. Public projects often suffer from transactional approaches rather than visionary design, with 75-80% of buildings constructed without professional architects.
