The supermodel - who has a net worth of $42 million - and her NFL player husband have hired a team of 100 builders to construct their dream home in Brookline, Massachusetts, in time for next summer.
The job is no small task, however, since the couple - who have two children, son Benjamin and daughter Vivian, together - want the entire 14,317 sq ft mansion to be completed by July.
TMZ is reporting that the modern five-bedroom four-bathroom house will sit on 5.2 acres of land
The plush pad will be the envy of German-born Gisele's fellow models, with its own pampering amenities including a basement spa, a pool with a Baja shelf - which allows you to tan in water - and its own yoga studio. It also has a motor court, a grand library with a balcony and a wine cellar.
Gisele, 33, and Tom, 36, also recently splashed out on a $14 million apartment in New York City.
Their three-bedroom city pad is located on the 47th floor of luxury residential tower, One Madison Park, offering incredible views of 'The Big Apple'.
