When Anna Spangler arrived at a wine and painting class, she thought the group of friends and her husband, a dairy farmer, were there to enjoy a fun-filled Friday night. So she was floored when HGTV Dream Home 2017 host Tiffany Brooks and a small production crew showed up to tell her that she’d won the stunning waterfront home on St. Simons Island, Georgia.

Before the session began, the owner explained that the camera crew was there to shoot a commercial for the studio. Anna had no clue what was actually going to take place.
