Clifford Charles Wendehack designed both Winged Foot and Ridgewood - and, I believe, Baltusrol. He was the master of German Tudor building architecture and wrote about the art of golf course clubhouses in an obscure 1929 book.
But these were not "small" - presumably the topic of this posting. These were all in the 40,000-50,000 sq.ft. level
The rule of thumb in clubhouse design is $125 per square foot above 10,000 sq. ft, and about $140 per sq. ft. under 10,000. So a 30,000 sq.ft. building cost $3.75 m. What a waste.
For small, let's think small - under 5,000 sq. feet. ($900,000 or less)
Here are some truly light, useful and appropriate clubhouses:
-The Dunes Club, Mich., is about 2,000 sq. ft
-Tobacco Road, NC, a 5,000 sq.ft. open room with vaulted ceiling
-University Ridge, Wisc., 4,500 sq, ft.
-Lane Creek, 4,500 sq.ft. modern lodge
-Caledonia G&FC, SC, 5,000 sq.ft. hunting/fishing lodge
My alltime favorites are the following "temporary" clubhouses, which could be/should have been kept as such:
-Chechessee Creek, SC
-Spring Island, SC
-Forest Creek, NC
