Around work I'm well known for the Lego in my office (counting in the 10's of thousands of pieces). Last summer I was tricked into building a Lego Space Needle for a space in our old building.
As you can see, I dropped the space needle when moving it to the stairwell in our building. It’s about 4250 pieces (+ 1 minifig if you can find it). I dropped it around noon, before xmas, took it home, and it was repaired by that night J After repairing it was even better (I didn’t like some of the top, and parts were made a bit stronger). There’s no glue, except for a dab on the spire. I started it last summer.
[The Lego Space Needle is currently (2012) in Building 85's stairwell]
