Great wall of China maybe?

There is a longstanding myth that the Great Wall of China is the only manmade object visible from space. In reality, many human constructs can be seen from Earth orbit. You can see the Great Wall, but it's less visible than a lot of other objects. And you have to know where to look.
Astronauts can see highways, airports, dams and even large vehicles from an Earth orbit. You can see the pyramids from space. You can see roads. You can see harbors. You can even see ships.
See link for some possibilities, depending on your definition

The question is vague. What do you mean by object? And biggest by height? volume?
The biggest building I can think of by volume would be Nasa's Vehicle Assembly Building.
