A cardboard house made using a Saran Wrap core

This is a cardboard house with a doorknob made from a plastic wrap core.

Use cardboard to build a house in any shape you like, and make double doors on the side.

Cut the wrap core to a suitable length and cover one end with silver origami paper.

Then wrap it around the side, and make another one the same way.

Use these as doorknobs and attach them to the doors to finish! If you add a ribbon or star decoration to the covered end, it will look even cuter.

You could even make a keyhole if you like.

Cardboard house with 3 bedrooms

In this idea, we’re making a cardboard house with a structure where, as you go down a tunnel-like hallway, you can access three rooms.

While a tunnel hallway might be tough for adults, kids would probably love it because it feels like a secret hideout.

It’s also fun that, after you pass through the tunnel, there’s a spacious, open-feeling room.

You’ll need quite a lot of cardboard to build it, but if you’ve just moved and have plenty on hand, why not give it a try?

cardboard house with a door

Here’s an idea for a cardboard house with a proper door that opens and closes! Once you shape a large cardboard box into a house, cut out the door section with a utility knife.

You’ll use the cut-out piece as the door, so make a clean cut.

After cutting it out, punch holes along one side of the door with an awl.

Make matching holes in the house, then secure them with zip ties, and your door is done! This version features a big bay window; if you turn the bay window into a counter, kids can even play pretend shop!

Foldable cardboard house

Cute and reusable: a foldable cardboard house

Let me show you how to make a simple cardboard house using cardboard.

Prepare a large box and lay it on its side, then cut off the top side panel and the flaps.

Reinforce the cut edges and corners with vinyl tape or similar, and attach a roof made from two pieces of cardboard joined together down the middle.

That completes the house, but if you want to make it foldable, make cuts in the bottom of the house, the side panel that will be at the very back, and along the edges where these two panels meet.

After making the cuts in the side and bottom panels, tape over them from the outside.

You don’t need to tape the corner cuts!

A stylish cardboard house made with wallpaper sheets

I made a cardboard house, but it doesn’t look very cute… In that case, why not try using wallpaper sheets? As more people are getting into DIY, a variety of wallpaper sheets are now available even at 100-yen shops.

Simply applying wallpaper sheets can make it stylish and turn it into a more realistic little home, so give it a try.

If you want to boost the style even more, decorating the window frames with tile stickers or using faux greenery as interior decor is also recommended.

Add a little extra touch to your cardboard house!

Dollhouses are just so cute, aren’t they? If you’re a girl, you’ve probably thought at least once, “I’d love to live in a house like this.” So let’s recreate a doll’s house using cardboard! After assembling the house out of cardboard, paint it pink, and make the door and windows heart-shaped.

Once you add a long staircase, the next step is to put floral curtains on the windows.

And guess what—the doorknob is shaped like a flower! It’s a cardboard house idea packed with everything a girl finds “cute,” so feel free to use it as inspiration and give it a try.

cardboard share house

Let’s try building a share house out of cardboard! First, create a communal living room in the center, then add personal rooms, wet areas, and hobby rooms around it.

The fun will be in how well you express the differences between each room! Build the shared spaces by brainstorming together.

You’ll likely have a great time even after the cardboard house is finished—chatting in the living room or inviting people into your own room.

This idea will require quite a lot of cardboard for partitions, so make sure to gather plenty in advance!
