I'm another person who has never heard of the course before. It's good of you to post the thread.
From the photos and your hole descriptions, I have a hard time understanding what makes the course "truly spectacular." There are nearly 60 bunkers and water in play on maybe 1/2 the holes. Some of the green complexes look good, but it's hard to tell much about contours. From looking at an aerial alongside the photo, there seem to be some interesting approach angles. The first nine rather intricately routed, but then also has some strangeness to me. Looks like after playing the par 3 third, the player has to walk (or drive) back 100+ yards to hit a tee shot on the fourth. Those "Jesus" bridges look cool, but how does a walking player make it from the 6th green to 7th tee? Just a longer walk?
Obviously, the success of the course needs to be judged based on what the owner wanted. If the owner wasn't concerned about some of the routing compromises, then we shouldn't care. However, when we compare this course to others, then things like that are fair game.
IMO, Fazio builds very competent courses. And no one hides a cart path like he does. They are generally aesthetically pleasing. Some of the bunkering at Santapazienza doesn't photograph very well - seems out of scale. It may look ok on the ground, but I would have to take your word for it. The brilliant white sand may or may not work for the location.
So what is it about Santapazienza that makes it spectacular? The uniqueness seems to come from being ultra-private, the "halfway house" after 5 holes, and the "Jesus" bridges. Each of these may make it memorable, but I don't see anything very special about the design from the routing, photos, or descriptions.
I have only played one "estate" type course - Wolf Point. I loved WP, so I'm not against the idea of a course with very limited access. I'm interested in what the course looks like, and this particular one in Brazil fails to excite. Give me a fortune to spend on my own course, and it would look a lot closer to Mildenhall (or High Pointe hop farm) than this. Perhaps just an issue of tastes.
