Adam,
Per your post, my new business, Prestwick 12 Golf was started to design, build and manage strategic, player-friendly and regulation length courses with expansive learning and practice centers and 6 hole loops. Developers will have the option of building 1,2 or 3 loops with homes around the perimeters.
The goal is to address what the golf industry (Golf 20/20) says is slowing the growth of the game: time, affordability, the difficulty of learning the game (incl. the intimidation factor) and the difficulty of most modern courses.
Design, construction and facilities will be very cost effective and course fairways will be generous to create several routes of play designed for both the novice and good player.
Most importantly, we will have a comprehensive instruction and playing program for new golfers, particularly women, juniors, families, etc. We are going to try to have something for every member of the family including miniature golf, small park areas and child care.
Green fees will be kept as low as possible, and we want to attract and retain new and occasional golfers. For 12 (or 18) holes green fees, should range from $12 to $25 depending on the location and the site, and walking will be encouraged.
In the Hilton Head area, where I live, there are high-end communities with all the things you mentioned but homes, incl. and memberships start at about $750,000.
