"He obviously has settled down in his personal life and, part of this, is planning for his future. Business pursuits and his foundation will play a growing role."
Woods came to know Lewis, owner of Premier League club Tottenham Hotspur, after moving in 1996 to Isleworth, developed by Tavistock.
The Albany luxury resort boasts a 71-slip yacht marina, a 20 000 square foot gym and a golf course designed by partner Ernie Els.
"Amazing homes, marina, amazing golf course," Tavistock managing partner Christopher Anand told Reuters sitting in the Isleworth clubhouse. "Horses, tennis. A sportsman's paradise, a business person's paradise."
"It's Joe and Tiger's tournament going to Joe and Tiger's place," he added about a merging of charitable events that benefit the Tavistock foundation and Woods'.
Woods, Els and fellow golfers Adam Scott, Justin Rose, Ian Poulter, Trevor Immelman and Tim Clark are among 20 athletes who call the resort home.
Pilson said this could be just a start of business expansion by Woods.
"If you look at Jack Nicklaus, Arnold Palmer, Greg Norman, I think they all make substantially more money today than they were making playing golf," he said. "The business opportunities open to Tiger would probably dwarf the other guys."
The natural competitiveness of a sportsman often translates to business, added Pilson.
"We had a relationship with Jack Nicklaus at CBS," he said. "I found his personality to be intense. Still friendly, casual, but I'm sure his business personality reflects his golf personality.
"Frankly the ones that continue in business bring with them the intensity and competitiveness that they exhibit in their sport."
