Probably the best example of flow to me is Cypress Point, starting in the open, going to the woods, back out in the open, then dunes, and then to the coastline. The design style is reasonably consistent but the terrain varies.
I had a landscape professor who liked to say constant doesn't equal consistency or continuity. Or maybe it was the other way around. In any event, there are some architects who feel that if you do a fw chipping area around the green once, you need to do it on every green, which is a good golf example of my professor's theory.
Let's face it, more golf courses are too much alike than far too different unless a reno builds three holes with another gca that makes no attempt to fit the holes in. Even then, nature sometimes takes care of things for those courses. I saw the 1979 Open at Inverness where Fazio's new holes were widely criticized as out of character with Ross. I went back to the Senior Open in the early 2000's and they fit better, and to my eye, there wasn't much rebuilding of the Faz bunkers to make them fit, but the mature trees helped tie it together.
I ended up with maybe 30 fw bunkering schemes and more greens. After realizing just how much a creature of habit most humans - including gca's - are I looked for the best place to put one each of those fw schemes, maybe twice on opposite nines and fw sides, without repeating. Some of the "schemes" were just simple things like breaking one big bunker into a cluster of 5. Sometimes simple things like doing a RR Tie wall 2 or 3 times instead of just once like you might on a tribute course helped make the feel like part of the course.
I always figured that as a plan drawer to start, if I strove for unique features, somehow I would have enough repetitiveness in my drawing style and preferences that they would hang together.
And, to break up the pattern of target and flanking bunkers, adding one centerline bunker, a few carry bunkers, etc., because I thought bunkering was too close to the old RTJ style of flanking one or both sides of the fw and was indeed too consistant. In fact, I often built one hole in the RTJ/Wilson 50s style as one of my efforts at variety.
Even with all those attempts at variety, I am certain that most could tell my style. My biggest exception is Wilderness and Quarry in far northern MN, where I have been told no one would guess it was the same architect.
I'm sorry for the slight digression, but these points are somewhat related to flow.
