I don't want to start a building architecture debate, but I'm not sure I'd put Wright in a strictly minimalist category (compared with the international school Wright's designs could be fussy), and he was a pioneer in modern building techniques. Here's a random quote from the web:
"From the beginning Wright practiced radical innovation both as to structure and aesthetics, and many of his methods have since become internationally current. At a time when poured reinforced concrete and steel cantilevers were generally confined to commercial structures, Wright did pioneer work in integrating machine methods and materials into a true architectural expression. He was the first architect in the United States to produce open planning in houses, in a break from the traditional closed volume, and to achieve a fluidity of interior space by his frequent elimination of confining walls between rooms. For the Millard house (1923) at Pasadena, Calif., he worked out a new method, known as textile-block slab construction, consisting of double walls of precast concrete blocks tied together with steel reinforcing rods set into both the vertical and the horizontal joints."
Fallingwater (in southwest Pennsylvania), his most famous private house, radically pioneered the use of concrete in residential construction.
All that aside, I'd like to suggest an additional analogy relevant to golf course architecture, and that is to Wright's interest in fitting his structures into the existing landscape. Fallingwater, again, is a perfect example. Although the land around the house was modified somewhat during construction, today the house and land speak as one. The top of a central boulder on which house sits forms the living room fireplace hearth . . . kind of like having the sheep build your bunkers naturally as part of the links (just dig a hole, no extra sand needed).
It may well be that Anthony and I are really talking about the same thing, but just coming at it from a different perspective.
