When i see the picture above with the masterplan i'm very exited how tall will be the buildings around. Looks surely 300m+

Why all of you, "level marking people", trying to look smart, while knowing a sh.t about construction?? Huh?
If you want to get an idea of how tall it is, just look at the truck in the lower right corner, and the man walking beside it. The truck height should be easy to find for anyone in SA who knows what make and model, it is. The man will guess at 5 - 6 tall. Now calculate that both of them are far closer to the lens than the building, and with some calculation you get the approximate height. Also in some shots from the other, there is a stairway beside the building, a new shot from that side would again answer the question.

^ Either that or the contractors/developers could kindly instead publish weekly or monthly up-dates detailing actual construction milestones like a number of considerate contractors/ developers do around the world who understand that there is real interest in their buildings.

But, of course, that would be far too much to ask for and would take away the joy we all have in trying to guess wtf is actually happening with this thing and then arguing about it...

Well, the developer is private and does not have to cater to investors in the stock market.

Even if we gauge nearby people, vehicles, etc., like was said, due to lens compression it can be slightly hard to gauge the true height. That and the lobby and lowest floors are usually double height or more, making a "floor" not necessarily line up with every single opening we see. But presuming the tall 15' / 5m+ floors there are for the lobby, we can at least gauge appropriate height from the openings.

It'll become easier once the standard typical floor appears from under the formwork to estimate the height.

=> 2rh + h² = c²
=> h(2r+h) = c²
Because r >> h this is very well approximated by
2rh = c²
=> c = √(2rh)
So the distance is only proportional to the sqare root of the height.
This might be a bit disappointing, but the visible area within the horizon is πc² = 2πch which is proportional to the height. In fact, the visual area is the product of the height and the earth's circumference. Or more poetically: the area of a ribbon around the equator with a width equal to the height of the building. This can also be proved in a more direct geometrical (less algebraic) way, which I leave to all of you as an exercise
What about if you're facing the other way?
