Tiger Woods -- Cheating Scandal House Gets MASSIVE Facelift

It's been 3 years since Tiger Woods' ex-wife Elin Nordegren smashed his SUV with a golf club -- over a massive cheating scandal that derailed his life -- and now, Tiger's finally starting to rebuild ... starting with the Florida mansion where it all went downhill.

Construction is already underway at Tiger's Windermere home -- the same home where Tiger famously crashed his SUV following a blowout argument with Elin over his endless philandering ... and Elin attacked the car with a freakin' golf club.
