Hi Donnyv,
In lieu of directly answering the question, I thought it might be prudent to ask a few clarifying questions first.
The big question I have about the project is: who is the course for? It sounds like it is on your own property, but who is actually going to be playing it? Is it going to be invitation-only? Pay-to-play private? Do you plan on hosting events there?
In my opinion, determining the overall demographics of who you want to be playing the course (and who will actually be playing it) is critical to the design process. I'd love to give more suggestions, if you're willing/able to identify your target demographic.
It will reside at our house so it will have to be a private course. There will be certain times and days where my family and I would like our privacy so the course will not be available 24/7. Def don't want people peeking into house windows or just showing up whenever.
I'll have it available for people to play if they contact me for permission and set up a tee time. Club and league nights during the week with casual and possible tourneys for the weekend slots would work. Just planning on keeping it small and low key for now. I have a small proshop with a restroom inside the shop and a practice basket for putting.
As far as players go, I've had newbs thru very good advanced players (who can pretty much be called pros) play the old course. Pretty much need multiple tees to cater to most players.
