Here's the origami house-making method translated into English (step-by-step): 

1. Fold a square paper in half (both horizontally and vertically) to create a "cross" crease.

2.  Fold the paper toward the center along the creases as shown.

3.  Flip the paper over.

4.  Fold the paper again as shown (aligning the sides inward).

5. Stand one side of the paper up as demonstrated.

6. Open up the folded part (as guided by the finger in the image).

7. Press the opened part downward to flatten it.

8.  Repeat the same folding steps on the other side.

9.  Fold the bottom edge upward to the designated point as shown.

10.  Flip the entire paper over (final step) — your origami house is complete!

Once you finish these steps, you can draw windows/doors on the house !
