Matt,
Interesting thread. I assume your point being that clubhouses are often sited on high ground to give a view of the course?
The driveable par 4 last at North Berwick plays from an elevated tee but it doesnt really feel like a downhill hole? The par 5 last at Castle Stuart played downhill also. And the 18th at Notts (Hollinwell) is downhill all the way.
Cheers,
James
