There is some disagreement as to what definition should be give for tallest.  Should it be the highest occupable floor? Should antennas be included? etc.  The Council on Tall Buildings and Urban Habitat defined four categories in which the "world's tallest building" can be measured:\n\n   1. Height to the structural or architectural top (including spires and pinnacles, but not antennas, masts or flagpoles)\n   2. Height to the highest occupied floor\n   3. Height to the top of the roof\n   4. Height to the top of antenna\n\nThe current record holders in each category is as follows:\n\nTaipei 101 leads in the first category with 508 m (1,667 ft); in the second category with an occupied floor at 438 m (1,437 ft); and in the third category with 448 m (1,470 ft).\n\nThe Sears Tower leads in the fourth category with 527 m (1,730 ft).

Any of the skyscrapers - Empire State Buildin, Sears Tower - would be fine, since they're also very blocky. For a greater challenge, you might even try the Pentagon, since it is a regular pentagon in structure.\n\nYou might start off with the Washington Monument, since it's nearly 1-dimensional (because it's so much taller than wide or deep).\n\nI'm American, of course, so I think mostly in those boundaries - I'm sure there are buildings in other countries that work, too.

Its called the "Sky City". The city will be so tall they will need an air conditioning system to provide oxygen because the atmosphere is to weak at that height. I believe they swaid it would house 4 million people. The city will be self sufficient. It would be possible to live inside and never have to go out again. It will be twice as high as the World Trade Center was! As far as I know its not being constructed yet.\nhttp://dsc.discovery.com/convergence/engineering/skycity/interactive/interactive.html

The Taipei 101 is the tallest building in the world at 509 metres / AP\n\nWorld's tallest towers\nFrom:  By Sara Clemence\nJanuary 18, 2006 \n \n \nThe Taipei 101 is the tallest building in the world at 509 metres / AP \n  \nFICTIONAL film apes aren't the only creatures drawn to great heights. Human beings have always been looking for ways to escape the ground--by building machines that fly or structures that stretch into the clouds.\n\nBut many of today's tallest are so high that even King Kong would get vertigo. \nWhen it comes to those buildings, what constitutes "tall" varies from place to place and year to year. The loftiest buildings in Europe are waist-high to those in the New World. \n\nIconic American buildings that once held records have been bumped down by new skyscrapers in Asia, which in coming years will be surpassed by new structures, including the Freedom Tower in New York City, Burj Dubai in the U.A.E., and others still on the drawing boards.

It depends on your parameters.  The tallest building in the world is the Mars drilling platform which is over 3000 ft tall including underwater structures.  The Sears tower has the tallest antenna, while the CN Tower in Toronto is the tallest freestanding structure on land.  The Taipei 101 has the highest occupied floor, however.  The Burj Dubai (under construction) will be the tallest building by far when it's completed, though.
