I saw the old photos of Newport & Winged Foot. Nice.
If you want to look at some old plans and old photographs of classic clubhouses, see if you can find a copy of the Clifford Wendehack's classic book 'Golf and Country Clubs' (1929 w/ limited printing / about 1000 copies). It might be available at large city or univ libraries.
The book has about 50 pages of discussion of clubhouse needs circa 1929 and about 100 pages of plans and photos. Features clubhouses at Everglades, Fishers Island, Winged Foot, Ridgewood, Lakeside, Morris County, Gulf Stream, Detroit Golf Club, Franklin Hills, Pepper Pike, Grosse Point CC, Quaker Ridge, etc.
It is large format, coffee table book, black & white photos of course.
If this site was Golf Clubhouse Architecture Atlas, GCAA, Wendehack's book would be the 'daddy' book.
Wendehack designed many clubhouses in northeast including Ridgewood, Winged Foot, etc.
