The Clubhouse and Golf Course are a traditional 4 step build, with the usual mix of requesting, crafting and, of course, homestead drops.
One thing to note is there is one craft used in both Stage 3, and Stage 4. So, if you have other stuff to do, don't craft all the carts and keep being able to request!
