Tom, you said "In GCA the most creative force is Nature....history has taught us that. "
At St. George's we found a couple of images that proved a few bunker faces fell in very early on. And yet, these bunkers evolved into something even more interesting than the original form. Where do you restore to?
Do you go back to the first built form?
....or do you go back to the form "nature" decided to make, because the architect for got one of the first rules of nature, the angle of repose.
You started with, "Does historical perspective (or a lack of) affect design?"
Yes, if you care about history, you will always make decisions with the history in mind. But you have to be careful how you apply the known history of a club.
I don't think you restore only to the architect's working drawings, but I do think you refer to them. I don't think you use only the on site features unless you can prove they are origional. I don't think you ignore evolution, because often the course has developed more character (than the architect had created) through growth. A good renovation/restoration involves a series of hard choices, it is not something that can be simplified to one technique.
I just don't get why everyone wants to pick a technique and say that one is more correct than others. All are judgements, and each part of a course requires judgement. The only rule I try to stick to, is if I'm not sure, I have a tendency to leave something alone until I am sure.
The other end to all this is not everything created in history is worth keeping. Some of the work is sub-par. A club has a right to make the choice to move on. I look at the Stranz course at Monterey Penninsula, and I am quite sure that regardless of what was there, they made the right decision to move on to something much better.
My rant is done.
