Elin Nordegren the ex-wife of tennis superstar Tiger Woods is building a mansion in North Palm Beach, Florida.

TMZ reported that the space is a whopping 21,000 square feet that has her native Swedish flag on top of one of the chimneys.

Nordgren purchased the home from her divorce settlement that left her with $100 million. She paid $12.2 million for the property and knocked it down to completely rebuild it.

US Weekly reported the property will have an Olympic pool, a spa and koi ponds.

Nordgren and Woods got divorced in 2010 after it came out that Woods had cheated on her with multiple people. The couple have two kids together a daughter, Sam, 5, and son, Charlie, 3. They were married for five years.

After the divorce Nordegren said to ABC News that she wanted to save her marriage, even though she was shocked by the multiple indidelities. She said to People magazine that she's "been through hell."

She told the magazine that she had no clue that Woods was cheating at the time.

ABC News reported Woods saying, "You know, it's a sad time in our lives. And we're looking forward in our lives and how we can help our kids the best way we possibly can. And that's the important thing."

Nordegren said according ABC News that she did not suspect any of the cheating. "For the last three-and-a-half years, when all this was going on, I was home a lot more with pregnancies, then the children and my school."

She added, "I wish him all the best in the future, as a person and as an athlete. I know he is going to go down as the best golfer that ever lived, and rightfully so. I feel privileged to have witnessed a part of his golfing career."
