How to Build a Four Floor LEGO House

Using LEGOs, you can build different structures from castles, to cars to houses. You can also create structures with multiple levels, such as a four floor house. When you create a four floor LEGO house, take into account the sizing for your floors as well as stairs to move between levels. Add support to your house to keep each floor structurally sound and able to hold furniture and LEGO people.

Things You'll Need

2 16 by 22 LEGO base plates
3 16 by 18 LEGO base plates
45 2 by 4 LEGO bricks
80 2 by 2 LEGO bricks

Instructions

- 1
  Place a 16 by 22 base plate horizontally in front of you and resting on a flat surface.
- 2
  Attach a 2 by 4 brick onto the lower right corner of the base plate so that the brick is horizontal and parallel to the lower side of the plate.
- 3
  Attach a second 2 by 4 brick directly behind the first on the plate. Repeat with three additional bricks so you have five bricks in total moving toward the back of the plate.
- 4
  Place a 2 by 4 brick directly on top of the second brick in the row. Place an additional brick on the third, fourth and fifth bricks of the row.
- 5
  Add a third brick to the third, fourth and fifth bricks of the row. Add a fourth brick to the fourth and fifth bricks and a fifth brick onto the fifth brick in the row. You have created stairs.
- 6
  Stack four sets of five 2 by 2 bricks to create four columns. Attach one column in the bottom left corner of the plate and one column onto the top left corner of the plate. Attach the other two columns so they are at the top and bottom of the plate, directly to the left of the stairs.
- 7
  Lay a 16 by 18 base plate onto the four support columns you have attached. The plate will not extend over the stairs or beyond the border of the bottom plate.
- 8
  Attach another set of stairs onto the second plate, this time to the far left of the plate.
- 9
  Add four support columns of five 2 by 2 bricks each onto the corners of the plate. Place another 16 by 18 plate onto the support columns, this time so it is flush with the left side of the bottom plate.
- 10
  Create another staircase on the right side of the third plate. Add four support columns and another 16 by 18 plate that borders the left side of the structure. You will have a four story house.
- 11
  Stack four more pillars and set them onto each corner of the fourth floor of your house. Lay a 16 by 22 plate over the pillars so that it is parallel to the bottom plate. This will be the roof of your house.
