Ill focus a bit more on the course for mine:
Land: To me, a truly great Course is most often on a great piece of land. For me, in order for me to see it is as "perfect" it would need to be sand based soil, micro undulations rippling throughout the course (with a few macro undulations for good measure), and some great scenery (mountains, ocean, or something)
Holes: Variety is the spice of life. Total Par isn't as important to me, but I guess a fairly normal par 72 would be fine. I think the Par 4 holes are really what give any good course its backbone, and I would need everything from a Driver-Hybrid type of hole down to a really good risk reward drivable par 4. I prefer my holes to be more strategic than penal, but sometimes you have to hit a golf shot at the right time so perhaps one golf hole or so per 9 that is truly penal golf architecture. Par 3's are key to having a great course. In my perfect course I would have one that requires a hybrid or so off the tee, two mid iron type holes that favor different shot shapes, and one really good short par 3 where missing the green requires some astoundingly good short game skills to save Par. A golf course can really go wrong with its Par 5's (especially for the average Joe) so I would keep all of these holes pretty strategic. I would prefer at least one to be a three shot hole for generally everyone that would play it, and two that are reachable for the long hitters if they take on some more risk off the tee or maybe even on the second shot after a good drive. I would make one truly reachable for everyone, but make sure it does give everyone some risk to consider (Im thinking Great Hazard Template..)
Greens: I am a sucker for a great set of greens. I prefer my "perfect" set of greens to be very undulating but kept at reasonable green speeds for the slopes. I prefer shaved edges around the greens to challenge the better players more and to repel shots. This will mean the average player will often be able to use putter from well off the green. Greens would reward well played shots from the correct angles, but also be a fairly large in size on average to give a safe area of the green to target when the flag is tucked.
Hazards: I would keep these more minimal than we see in a lot of modern golf course architecture, and I think I would prefer to rely more on bunkers than water hazards (unless natural). The hazards generally need to be playable, but definitely something a players wants to avoid if they want to score well. I do think a few hazards (especially on the ore accessible holes) would need need to be a bit more penal and really give the good players something to consider.
Routing: This kind of falls in line with holes section above, but I would want the variety of golf holes spread out throughout the round, and for some reason would like a "Pete Dye Finish" (Risk-Reward Par 5, Short but Penal Par 3, and very strong challenging par 4). My perfect course would be routed in such a way to ensure that the best views are taken advantage of, and the wind is encountered from all directions. The course would be generally walking only (with special permission as necessary for carts)and therefore the green to tee transitions would be smooth, and the asks in between quite pleasant. Not really a "routing" feature per se, but I would prefer to have tee offerings ranging from 6800 max to just below 5000.
Organization: Semi-private club. I like the model. 4-5 days a week where only member and their guests can play, and 2-3 days a week where if planned in advance a visitor can schedule a tee time.
So now the only question I have is...who wants to put up the money for me to realize my dream? 🙂
