EXCLUSIVETom Brady and Gisele Bundchen are HAULING ASS on their massive new construction in Brookline, MA -- TMZ has learned, they're employing roughly 100 workers per day to get the job done by this summer ... and we've got pics of the site.
Sources close to the job tell TMZ, Tom and Gisele want the whole project completed by July ... which is a tall order, considering the 5-bedroom 4-bathroom house is ENORMOUS ... 14,317 sq. ft. to be exact ... spread out over 5.2 acres.
We're told the plans for the mega-mansion include a basement spa, a motor court, a pool with a "Baja shelf" (perfect for tanning in the water), a library with a balcony, a wine cellar, and even its own yoga studio.
