ELI5: Is there an upper limit to how tall a building can be?

Assume a 50,000 square feet cuboid building on a plain, firm land, in a landlocked area and not on any major earthquake prone areas. How tall can it be theoretically?

The limit is based on the weight the construction can carry. If the construction cannot carry that amount anymore, then it will crush under its own weight.

For example, the World Trade Centre towers, you might have heard a little bit about it. They were 400 meters high. The metal and concrete construction were properly specced to hold its heights for the first 35 years: Nothing wrong with it. Now due to an external incident, the metal construction is affected and lost its strength. It then collapsed under the weight of the construction on top of it and it folded nicely on top of itself.

The space elevator principle is based on a string of 36 thousand kilometers. Currently there is no material which can carry that weight without breaking.
