The Palm Beach Post reports that Elin Nordegren plans to build on the North Palm Beach lot she bought last year. The lot is about 225 kilometres southeast of Woods' home in Orlando.
The newspaper reports the mansion that was demolished was a two-storey, 17,000-square-foot-home built in 1932. It had a swimming pool and an elevator.
Realtor John True of Oceanfront Realty says the lot is in the Seminole Landing development, among the most exclusive in Palm Beach County.
Nordegren divorced Woods in 2010 after learning he had a string of affairs during their five-year marriage. They share custody of the couple's two children.
