After the postmodern architectural movement in 1960, the scenario of urban development started to change. In the late 1990s the style of postmodern architectural development finally began to proliferate and became dominant. Since then it has divided into a multitude of new propensities including high-tech architecture, neo-futurism and deconstructivism. In turn, that resulted in the construction of astounding structures that we also call by the name of modern wonders of the world.

Most of them often carry beautiful statements of a nation’s wealth, pride, and power. But these architectural marvels don’t come cheap. From planning to completed construction, the costs of those buildings regularly reach the billions. That said, here are the seven most expensive buildings in the world.
