It really depends on how you define building.\n\nIf it is by highest point (including antenna), then it would be the  Sears Tower in Chicago, USA\n\nBy architectural top (top of roof)? Then it would be Taipei 101 in Taiwan.\n\nHope that helps.\n\nwiki has all tallest structures by category. Check the link below for more.

It depends on how far up you are.  There is a longstanding myth that the Great Wall of China is the only manmade object visible from space. It and several variations on the theme are great fodder for water cooler arguments. In reality, many human constructs can be seen from Earth orbit.\n\nShuttle astronauts can see highways, airports, dams and even large vehicles from an Earth orbit that is about 135 miles (217 kilometers) high. Cities are clearly distinct from surrounding countryside, and that's true even from the higher perch of the International Space Station, which circles the planet at about 250 miles (400 kilometers) up. \n\nEgyptian pyramids have been photographed from space several times with standard digital cameras and high-powered lenses. The largest pyramid at Giza, on the outskirts of Cairo, is 745 feet (227 meters) wide and 449 feet (137 meters) tall.\n\nWith binoculars you can see ships on the ocean.

The earliest ceremonial buildings were erected at Teotihuacan about 100 B.C. Within a few centuries, Teotihuacan had mushroomed into a huge city dominated by the great 'Pyramid of the Sun'. This sacred, truncated edifice stood 210 feet high and 650 feet square, a vast pyramid of rubble, adobe mud, and earth all faced with stone. A wooden temple on the summit of the pyramid afforded a spectacular view of the sprawling city below.

Too big for it to ever have been built.\nToo many animals to ever carry enough food.\nToo many animals for the smaller ones not to have drowned/suffocated in all the waste they animals would have produced.

*Counting* spacecraft, the fastest man-made object (so far) is Helios 2, which got up around 150,000 mph.  That's still less than 1/4,000th of the speed of light, so we have a way to go.
