I just built a giant board, and then I make walls from FatDragon or from foam. You have nearly full control then. For unique floors, there are plenty of tiles you can buy/ get for free. I just use stick glue on foamcore. I suppose some might peel off some day, but it's cheap. Who cares if it comes off?
If you have any interest in 3D, let me know, and I can start posting tutorials on using foam and paper terrain together. Some of what my son and I have built has been insane (4x3x3 version of Helm's deep for example), but most is really easy to make.
