Children love a cardboard box playhouse. Usually they are built, played with for an afternoon and then thrown away, or hopefully recycled. This Instructable will show you how to make a playhouse that can be built using only two bicycle boxes, in about five minutes, that can be flat-packed for storage, so you can reuse it again and again.
Step 1: Materials
All you need is two bicycle boxes. That is it!
Step 2: Tools
You only need three tools.
1. A tape measure
2. A knife
3. A marking device
Step 3: What kind of box?
I used two bicycle boxes. You can get these for free at most bicycle shops (remember to say thanks). Try and get the double walled cardboard, it is much stronger than single wall cardboard. The boxes I got were 30 inches tall x 7 inches thick x 53 inches long.
Step 4: Flatten
Some bike boxes are glued, some are glued and stapled. Remove all the staples on the top and bottom and open the flaps. Try and not damage the flaps. Then lay the box flat.
Step 5: Measure and mark the center
Measure the flat box. Remember my boxes' dimensions?" 30 x 53 x 7 These dimensions worked out perfect for the roof and floor. (you'll see why later) Now that the box is flat, it is 60 inches wide. Make a mark in the center. My center is 30 inches, yours might be different. Mark both boxes.
Step 6: Fold your box
Now fold on the center mark. Fold both boxes.
Step 7: Open the box and stand it up
Open you box and stand It up. Tuck the bottom flaps into the inside. Leave the top flaps sticking up. Your walls should make a square, when viewed from the top. You will use the other box to make the roof and floor.
