Gisele Bündchen is makin' moves ... setting up her homestead right next to her ex-hubby.
TMZ has confirmed ... Gisele closed on an $11.5M home in the Miami Beach area, right across the creek where Tom Brady is building a house.
Sources connected with the former couple tell TMZ ... Tom knew Gisele was buying the house and it all has to do with co-parenting -- making it easy for the kids to go back and forth.
