At this point, minimalism is nothing more than a sales tag that might get one gca a job over another......
Even in technical terms, minimalism is a matter of degree, always. For example, if it is defined as mimicking nature, if there are no sand blow outs on a given site, does that mean there would be no bunkers? Fewer than normal? Or that the bunkers would have a certain style?
Many here opt for the last defintion, usually picturing the Sand Hills blowout bunkers, but those are natural there, not natural anywhere else. If you had a Wisconin or Texas course, would the model for the bunkers be the artifical stock tanks that dot many properties. While not natural, they are the most dominant site feature in many cases.....
I always lean towards the definition of using every natural feature first, and adding the minimal amount of artificial features to create a fine course.
The second part is creating those features to blend with the landscape. Years ago here on GCA, a Euro based architect said that when he had to move dirt in the fw for drainage, he would follow the existing swales and increase the grade for drainage. I think he also said he would never exceed double the existing grade for any feature (If a green sat on a 10% slope, no grades around it would exceed 20%) as a good starting guide for his work.
Sidebar - is following the contour as above the best route once you have admitted the need to grade a fw for drainage? What if the swale occurs in the prime landing area? Would it be just as acceptable to move it out of play, perhaps challenging or forcing the distance control of a longer hitter as opposed to leaving everyone who hits the main landing are with a hanging lie in the name and mantra of "minimalism?"
While granting that the swale in any location will affect some play, and in often unpredictable ways, should the goal of golf design be to leave it as is, or to locate it (through routing if possible but earthmoving if not) to a location where the the odds of it influencing play become greater?
And, as you can see from the above, and my natural vs man made threads, I am not sure I care about minimalism at all! The end result needs to look good, play well, and not be a real burden for the Owner in maintenance (which can vary a lot from project to project in definition)
