Whether you are following Fortnite Chapter 7 Simple Build Rollout: How the New Default Mechanic Works and How to Opt Out, here is deep analysis worth reading.

Turning off the mechanic takes less than thirty seconds once you know where Epic relocated the building toggles in the updated Chapter 7 interface. Follow these steps to restore classic building settings:

  1. Launch Fortnite and open the main lobby screen.
  2. Press the Esc key on PC, or press the Options / Menu button on a console controller.
  3. Select the gear icon on the left sidebar to open the Game Settings menu.
  4. Navigate to the Game tab (represented by a gear icon along the top menu strip).
  5. Scroll down past the Movement section to locate the Building header.
  6. Find the entry labeled Simple Build and toggle it from On to Off.
  7. Look directly underneath to ensure Turbo Building remains set to On.
  8. Press Apply (Triangle on PlayStation, Y on Xbox, or the Apply button at the bottom-right on PC) before closing the screen.

Once applied, the change takes effect immediately without requiring a game client restart. Entering a match will restore your individual piece selection on either mouse and keyboard or gamepads.
