Our user InEx / FromAustria found here the nice site of Andreas Charell http://www.andreascharell.de/modellbau.php , who has a good bunch of nice Civ4 buildings on his page.
For non german speakers: He says on his page that these models are free to be downloaded and used in mods (only prerequisite: Give proper credits), but you are NOT allowed to modify them yourself, unless you have asked him for permission.
Edit: Thanks el hidalgo for the link below
.
And he's also right about Pie, he found that link originally.
