Try the Google 3d warehouse,
also try the Italian site archiradar,
also learn about creating billboards: they are 2d images (jpg or tiff) applied onto 3d elements such as a wall, then via the lightworks shaders you get the 2d image placed anywhere at any angle in your rendering and it will even cast shadows. Of course not really 3d, but suitable for any rendering situation. Anything 2d can be used in this way, increases the possibilities. Nice benefit is once made and stored into a project or office library, they are reusable in any project.
Any excuse to go bare, californians take, yes?
