He Annex mansion Free 3D model

This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 OK, Double E. Here is onother one from a few years ago. Eliminated the sparkly edges by making a new style with black as the reverse side of the faces. Looks much better. Had fun with this one. Next up, a small one. The other one is 17MB, which is too large for here. Any Ideas? Thats all that I could extract from the cube castle. However, there is that steep roof on the new version...Hmmm, super large A-Frame??? New elevator on cube castle is super cool. Kinda breaks up the Escher-esqu look of the courtyard, tho. I am referring to Ascending and Decending by MC Escher.
