It's questionable whether the fuel savings would outweigh the resources/costs of construction. You'd have to be pretty confident of a stupendous amount of satellite launches and whatever else rockets do, which is hardly anything. As well as hoping no other technology appears before the building's paid for itself.

Energy savings wouldn't be amazing. It still takes a lot of energy to lift a spacecraft up a building.

What if the building collapses? Would be worse than a space elevator collapsing!

Either way, these things could be built in uninhabited areas or even on the ocean floor I guess.


Have you seen this? It looks a lot more realistic than a building that does little more than hold itself up:
