Infinite. But that assumes a liberal definition of "building".

There's talk of a "space elevator" that's basically a wire extending from earth into space. This would use centrifugal force to stay up. A cab would travel up and down the wire with people and cargo.

You could carry this concept forward by attaching living modules at various points along the route, or even a continuous string of them. I'd suggest a series of additional wires (many of them) to handle the additional forces.

Is this feasible, even theoretically? Hell if I know.

I believe there is enough oxygen to sustain life below 10,000 feet.

People can acclimate to heights way above 10,000'. The key is staying at high elevation rather than coming down every day.

Regardless, we're talking theory here. People can live in deep space with proper support, so oxygen is only a factor to overcome, not a strict limitation.

If a pressurised aircraft can fly upto 36,000ft with few, or nobody getting sick, then why would it be a problem living at this altitude? I assume that such a tall building would obviously have to be pressurised, thereby negating the effect of altitude sickness.

An other problem is that how on earth are you able to build this kind of building? Up to 5 km it might get pretty hard I'd say. Helicopters can't fly above the one line. Workers would have to wear oxigenmasks and some kind of uniforms.

"Noone in their right mind would construct a building that tall"...

Wouldn't be so sure. After all, there will always be someone who wants to break the record. Inevitably some building somewhere will surpass BD and then another one will surpass that one and so on, and so on, and so on.

Two Additional Factors:

Building Materials - The type of material skyscrapers are built with, whether it be concrete or steel, all have maximum forces they can withstand. Building size and height is limited by the heaviest load these materials can support.

Diameter - Visions such as Frank Lloyd Wright's "The Illinois" would never work, because the base would have to be completely filled with elevators and utility lines to serve the upper floors. If one is to design a building of this size, it must be a lot wider at the base, perhaps shaped like a Hershey's Kiss.

once you pass the atmosphere, you have to worry about radiation and space trash. a tiny rock travelling at 26,000 mph can have a pretty big impact. but more realistically, to build above 3,000 ft, you will start have to thinking about the ground below you. at that weight, unless dispersed greatly through a wide base, would liquify today's materials. cost is a huuuuuuge stopping point.

with the Today's technical possibilities i think Towers with 1500m-2000m are realistic.

There was this Episode on Discovery Channel about a pyramidic Structure housing an entire City.
Link to the description

It's all a bit far-fetched, but not impossible. I guess Structures like these can reach higher than the Standard "Tower".

But there is always a limit. At altitudes where the buildings have to be pressurized, the cost would be immense. Besides that, I wouldn't want to live there if I could not even open a Window.

How tall can buildings go? How much money is there in the world?

I think it would be theoretically possible to build a building where the penthouse suite is almost free from gravity - its a pretty stupid idea though.
