If you're building in a bog, you can maintain stability if you don't try to dig it out nearly as much as you would land. Also taking buoyancy into account.

I always thought that was just Dutch people being Dutch and getting more floorspace without buying more land. Any of the skyhooks I've seen just extend out above the top floor. I suppose there's more risk of breaking windows if the load swings around as it goes straight up though.
