As far as I know, aircraft are built at the manufacturers plant whether that is Lockheeds Plant 42 or Northrop or Boeings equivalent, and then
transported in pieces for convenience to Groom Lake by air or land and then assembled in a hangar there.
I know that this was true for the A-12, HAVE BLUE, SENIOR TREND and the U-2 (OXCART).
Here is an image of the A-12 being transported by road to Area 51. As you can see its "vertical" control surfaces are not yet attached, these may be

Here is an image of the first U-2 being delivered to Groom Lake by air. Its wings clearly aren't attached:
Some maintainence is done at the base on the test craft. It would be pointless to have to dissemble them and transport back to california each time
any repairs were needed.
