Firetruck Fort

Jessica, the mom behind Utah Country Mom, built this impressive fort for her firefighting-loving toddler using a card table as the base. 

Simple Sparkle Light Fort

A normal fort becomes something magical when you add sparkly lights to the mix. We love the one spotted over at graphic designer Bar Lucci's family blog Art Bar

Cardboard Castle Fort

We’re totally wowed by Brandon Tran’s cardboard castle. If you’ve got extra cardboard boxes (and a fair amount of patience), you can make one for your house too. 

Corner Tent Fort

Make a cozy reading nook for your little bookworm using silky fabric and a big quilting hoop. Head to parenthood blog Mama Liberated to see how she designed this comfy corner for her kiddo.

Easy Cardboard Box Fort

If you’ve got a big box on hand, you can make this cool fort from The OT Toolbox. It’s studded with Christmas lights, and you can also make it into a sensory box by adding dried corn or other materials.

Fort Boards

Indoor afternoons just got a whole lot more fun! Fort Boards are the perfect open-ended building toys that combine imagination and STEM skills and will keep littles busy for hours. Construct domes, vehicles and various-shaped forts with these colorful and BPA-free pieces that can build up to 20 square feet of construction but fold down for easy storage. Snag a set here

Upcycled Newspaper Fort

Gather up your old newspapers to make this genius fort from Modern Parents Messy Kids. You can leave the structure as is, or throw a blanket on top to make it extra cozy. 

Build-Your-Own Fort Kit

If fort-building isn’t your forte, you can snag a kit like this one from aidenandtuck on Etsy. It’s got everything kids will need to make an awesome fort (minus the sheets or blankets). You just might be surprised by the creations they come up with. 

A-Frame Fort

If you’re handy with a drill and a sewing machine, give this A-frame tent DIY from family blog Cakies a try. It’ll make the perfect kids-only hideout for rainy days and chilled-out evenings. 

House in the Hallway Fort

This hallway house is a truly portable wonder. It's a shapeshifter that can be set up in the hallway, or even over a staircase for older kids who want a two-story play space. Our favorite bit from mom blog ikatbag is how interactive the creation is! 

Cardboard Rocket Fort

If you’re feeling crafty, check out this crazy cool rocket fort from Kate’s Creative Space. A cardboard box can become something completely new after adding colorful paper, tin foil...the sky’s the limit! 

Bunk Bed Fort

If you’re skilled with a sewing machine, whip up this bunk bed fort from craft blog A Lemon Squeezy Home. Kids with handsy siblings will love the sweet fall-proof design.

Cozy Reading Nook

Here’s another take on the reading nook from Small + Friendly, a modern homemaking blog. With a mini futon and a pretty canopy, littles will love relaxing in this cozy corner. 

Impressive Dome Fort

Budding architects are sure to appreciate this geodesic dome fort built by one talented parent. All the details can be found on Instructables. With cardboard, box cutters and some paint in hand, this could be the perfect way to spend a rainy weekend—your kids will definitely thank you! 

Under-the-Table Fort

There's no structure more stable than your table! Take a cue from Mama Papa Bubba and put together a quick hideaway using a bedsheet and a table.
