I think I would go with Askernish/Machrihanish Dunes meets the United States.
More natural, more rugged look...and I would market that as a good thing.
Educate my patrons/members/consituents about the virtues of brown courses, fast and firm, slower more natural greens, etc.
And my whole mantra would be sustainable golf...good for the environment...and good for the club's pocket book.
I would hire a great Keeper of the Green (and I would use that term) and I would make him front and center at the club. Always visable, always interacting with golfers before during and after their rounds. Hopefully this would instill a feeling of how important and special the actual course is and, therefore, inspire golfers to take care of it and treat it like it is special.
I would have "club" work days where we all get together for a nine hole match on the weekend end and then spend the other 2 hours (that normally would be spent playing the other nine) and I would assign a foursome (at least) to a hole and have them help the Keeper of the Green with maintenance on that hole. Ensuring divots are repaired, ball marks are fixed, etc.
Then after that a community type dinner. I am thinking once a month on this type of thing.
I could go on and on...but I will stop. I think you can see my "mark" wouldn't really be a design concept but a mindframe of what golf is all about.
And then once a year, we would offer a club trip to the most natural "Land fit for the purpose", understated, TRUE golf course...
SHADOW CREEK!!!!!
Well, all of that was true until the last sentence or so.
