It depends on whether the building is worth preserving. Historical monuments, for example, need to be saved because of their cultural significance. On the other hand, if a building is old, ugly and has no importance then I don’t see why we should preserve it.

Yes and no. The facilities are better, rooms are often fully equipped with whatever you may need. And there are lifts and convenient stores so you don’t have travel much to get what you want. But these buildings are also bad for the environment; their construction and operation release a lot of waste and heat, which pollute the environment and contribute to global warming.

If the buildings are really important to the country, yes. If they are well preserved, it will help bring in income that would be spent on the maintenance.
