there are few things more frustrating than when an Owner "decorates" the course in a manner inconsistent with the design intent.
I use the analogy of a great building architect having his work be ruined by a poor interior designer who knows nothing about furniture or lampshades, etc.
God is in the details -- an a classic architectural expression-- and many of these final details on a golf course, such as the signage, benches, etc, definitely may add or detract from the overall experience.
As much as I pontificate here -- I must admit, that this part of the project is often overlooked by the golf course architect, mostly because it is not in his or her typical scope of services. But, I am contemplating making it a standard part. Mies Van Der Roh (I screwed up that spelling) -- a modern architect (skyscrapers, etc) would often design furniture as well. Golf course architects are often done with the project when the grass is sown, and leave the final details to the superintendent or Owner. I think golf course architects should have more input into these final "decorations" -- that way they will fit more consistently with the overall concept for the course.
What truly made me feel this way was when one of our clients put cartoon characters on one of our courses as tee markers -- a shark, a tiger, a bear, and a walrus -- get it. It totally took away from the concept and made it seem like Wally World.
