"I guess what we're looking to do is create something that future generations can benefit from."
The two clubs are spread across 102ha. Once the design of the new layout is finished, there will be spare ground which will be sold to help pay the costs of the development.
Due diligence and legal issues are the first order of business. The plan is to have that signed off by about the end of March.
The intention is that the two clubs, which have hosted 17 New Zealand Opens between them, will continue to operate as they are until the bulldozers arrive.
The two courses have 37 holes between them - the Grange has 19 - and at all times it's planned to have 18 holes available for members, but they will vary as work progresses.
"Everybody understands exactly what it is we're attempting to deliver," Rob Chemaly, chairman of the Grange board, said yesterday.
"It's about a world-class facility that Auckland and New Zealand will be proud of. The membership of both clubs have made a very courageous decision because they have said 'this isn't about us, this is about the future'."
