I did my house in sketchup and linked it into google earth - but as a local file, I did not submit it for inclusion I would have, but it has approx 2 megs in texture files - it was a surprise for my wife and I didn't want to skimp on the detail. I had a link to a kmz file somewhere around here but I can't find the link in the forums right now (I can figure out where it is if anyone really wants).
