Making a cardboard dollhouse is such a fun and creative project. It’s budget-friendly, customizable, and a great way to experiment with your crafting skills.
But let’s be real—cardboard isn’t exactly known for its strength or beauty straight out of the box. My first attempt at a dollhouse ( I think I was about 15 years old), looked like it was being held together by hope and courage. Lesson learned hahaha!
Over time (and with a lot of trial and error), I’ve figured out some ways to make cardboard dollhouses and cardboard furniture sturdy enough to survive curious hands or overly enthusiastic pets.
I’ve also found plenty of tips in the dollhouse community and share them with you today!
How to Build a Stronger Cardboard Dollhouse?
Let’s talk structure first because if your cardboard dollhouse isn’t sturdy, no amount of cute wallpaper or fancy furniture will save it.
Reinforce Walls with Layers of Cardboard
Doubling up your walls is a game-changer. Glue two pieces of cardboard together, but make sure the corrugations (those little ridges inside) run in opposite directions—one layer vertical, the other horizontal. This trick makes the walls so much stronger.
If you want to go the extra mile, and this is a tip I found on Reddit: sneak popsicle sticks between the layers to act like tiny support beams. (to be honest, here, I think that might be too much fuss hahaha)
If you’re feeling fancy (and your budget allows it), you could even use matboard or greyboard instead of regular cardboard for an ultra-sturdy build. But then we’re deviating from the topic in this article.
Support Those Floors
Floors are often the weakest part of a cardboard dollhouse—trust me, I’ve had a few saggy situations.
What you could do is add strips of cardboard underneath the floors for support or use wooden coffee stirrers, so that they don’t collapse in the middle.
Popsicle sticks also work wonders and add extra charm if left exposed.
Pro tip: When you’re gluing sections together, weigh them down with a book while they dry.
Just don’t forget to use parchment paper between the book and the glue unless you want your favorite novel to become part of the house 🙂
Finish the Edges
Exposed cardboard edges can look messy and weaken over time. Cover them with paper strips, washi tape, or even foam sheets to clean them up and add strength.
You can also fill the corrugations with spackle or a glue-and-filler mix for a smooth finish. It’s a bit of work but so worth it when your house looks polished.
Create multiple smaller rooms
As you can see in my own dollhouse created from cardboard (don’t laugh lol), I have created different small rooms, so they reinforce the whole dollhouse as a whole.
(this is just a quick, non-professional cardboard dollhouse though, you can use the tutorial to work on together with your kids 😉 ).

How to Make Your Cardboard Dollhouse Look Amazing
Now that your dollhouse is rock-solid, it’s time to give it some personality. This is where the fun really starts!
Amazing people have built amazing-looking cardboard dollhouses all over the world, and to be honest I never did a terrific job like that lol!
Here are some tips that I found in the dollhouse community:
Add Texture and Style to your exterior walls
If you want to get fancy, try mixing fine sand into your paint to add texture to the walls.
Or, for a smoother look, cover the exterior with kraft paper or Mod Podge before painting.
You can also layer strips of cardboard or popsicle sticks on the outside to mimic wood paneling or beams. This adds depth and makes the house look like a miniature masterpiece instead of, well, a cardboard box.
Get Creative with Decorating
Here’s where you can let your imagination run wild:
- Dollhouse Wallpaper: Scrapbook paper, wrapping paper, or even peel-and-stick wallpaper can transform plain cardboard into elegant rooms.
- Windows: Cut out windows and glue plastic film (like from food packaging) for the “glass.” Add trim or shutters for extra flair.
- Carpets and Rugs: Use felt, fabric scraps, or even learn how to print out dollhouse printable rugs on fabrics (yes, you can!).
Even old wrapping paper can make a cute area rug! - Lighting: Add tiny battery-powered fairy lights or make a glowing oven with a mini light bulb. Seriously, how cute is that?
- Add Dollhouse furniture: Besides the dollhouse itself, did you know that you can also create dollhouse furniture from cardboard?
PS. Can I be so bold as to promote my own Etsy store with dollhouse printables? There will be lots more patterns added soon and I intend to keep it growing!
Seal the Deal
A layer of PVA glue or Mod Podge seals the cardboard, making it stronger and easier to paint. For added texture, mix a bit of filler into the glue and apply it to the walls. It’s like giving your dollhouse a protective shield.
My Final Conclusion
Making a cardboard dollhouse that’s both sturdy and beautiful doesn’t have to be complicated. Whether you’re building it for yourself, your kids, or just for fun, these techniques will help you create a masterpiece that lasts.

Hi everyone!
My name is Lizzy, and I am an amateur miniaturist obsessed with everything in the dollhouse and miniature world, ever since I was a teenager.
So far, I have created 2 dollhouse projects, a backyard shed and a miniature treehouse, tons of DIY dollhouse kits, and “hacked” some.
I also created a fairy garden, and lots of small and simple miniature projects on my YouTube channel. (mostly made from trash or everyday items).
I love to write as well about all things happening in the miniature world, hence the reason why I created this blog!
I wish you happy reading and crafting!
