How to Construct a One-Box Cardboard Train and Rocketship

Fun project for making a  2-in-1 cardboard playhouse out of the same cardboard box! Make a Rocket Ship and a Percy the Train from Thomas the Tank Engine!

Materials Used:  2 in 1 Cardboard Playhouse

– Large Cardboard Box – Craft Paint & brushes – Craft Knife – Strong Glue – Black Sharpie Pen – Clamps

Step 1: Find a Big Box

An irregular shape like this toilet box works best, but don’t worry if you don’t have that; you can always join two boxes together to make the shape you want.

Step 2: Plan your Design

I wanted one side to be a rocket ship and the other side to be a train. I decided this after looking at the box from different angles.

Step 3: Start Cutting

I started by cutting the rectangle from what would be the back of the train cab. I then cut that piece into 3 triangles for the rocket ship point (at the top) and fins.

Once the safety prep was done, I started putting together the shapes that would turn my cardboard box into two cardboard playhouses.

Step 4: Assembly

Once the glue is dry, all the structural work is done.  And you can start painting, which is the fun part!
