How to Make a LEGO Spinning Door

by Scott Kratochvil

Airports, skyscrapers and other buildings employ spinning doors to save energy or restrict the number of people who can enter a building at once. In the world of LEGOs, a spinning door can add a kinetic touch of realism to any building. Chances are that if you own a collection of LEGOs you'll have the required pieces.

Items you will need

  • LEGO building blocks
what is a fallback
Step 1

Ensure you have the most important pieces: two revolving disks with at least four building slots on top and bottom. Four tall LEGO glass panes are also helpful, but you can substitute standard blocks if necessary. If anyone asks, you can claim that the glass is tinted!

Step 2

Begin construction with a wide, flat foundation piece for the whole building. Add the first revolving disk where you want the door to be. Attach four windows on top of this, one in each cardinal direction.

Step 3

Strengthen the top of the door with a square four-slot piece, then add flat pieces to the top of each window to keep things even.

Step 4

Add the second revolving disk to the top of the door.

Step 5

Build the walls nearest the revolving door up to the height of the door. If you have more window pieces, consider using them here to create a transparent front to your building. Lay a long, wide piece across the top of the walls and over the disk atop the revolving door. The door should rotate free and easily. Now that you have the completed the building's front, the rest should be a snap. Simply build three more walls and a roof.
