If you’ve just added a second set of jumbo building blocks Biggo Blocks (or you’re thinking about it), welcome to Big Build Mode.
One set is perfect for learning the basics for stacking, simple forts, starter towers.
But once you have 2+ sets, the scale of what your kids can create changes completely. Suddenly, they can build structures they can walk into, crawl through, and play around in for days instead of minutes.
Here are 7 mega build ideas that really shine when you have more jumbo building blocks to work with.
1. Walk-In Block House
A classic for a reason. Turn your play area into a mini neighborhood.
How kids use it:
-
Build walls tall enough to stand beside and a doorway they can walk through.
-
Add “rooms” for pretend kitchens, reading nooks, or stuffed-animal bedrooms.
-
Decorate the outside with color bands, stripes, or “window” patterns.
Why 2+ sets help:
You’ll need enough extra large building blocks to build full-height walls plus a sturdy door frame. With a single set, the walls tend to stop at kid-knee height; with two, you can build a structure that actually feels like a little house.
2. Floor-to-Ceiling Skyscraper
Turn simple towers into a “how high can we go?” engineering challenge.
How kids use it:
-
Start with a wide base, then build layer by layer toward the ceiling.
-
Experiment with color-coded floors or “observation decks.”
-
Use the build as a backdrop for cars, figures, or city pretend play.
Why 2+ sets help:
Mega height requires extra stability. Additional jumbo blocks let kids create thicker bases, reinforce corners, and repair sections if they wobble or fall—great practice in trial, error, and problem solving.
3. Giant Maze or Obstacle Course
Turn the living room or playroom into a life-size puzzle.
How kids use it:
-
Lay out twisting pathways with low walls to crawl or walk through.
-
Add “checkpoints” they have to reach or color zones they must follow.
-
Race toy cars or balls through the maze and see which route is fastest.
Why 2+ sets help:
Mazes eat pieces quickly. Two sets of jumbo building blocks give you enough blocks to build longer paths, more turns, and multiple routes, so kids stay engaged tweaking, shortening, and extending the course.
4. Double-Lane Race Track Garage
For kids who love vehicles, this build becomes a full play ecosystem.
How kids use it:
-
Build two parallel ramps or “roads” side-by-side.
-
Add walls and arches to create a parking garage or pit stop area.
-
Use different colors to mark lanes, parking spaces, or start/finish lines.
Why 2+ sets help:
To create ramps, walls, and side structures at the same time, you need more volume than a single set usually offers. Extra jumbo blocks mean kids can keep adding details like tunnels, bridges, and barriers without running out halfway through.
5. Mega Robot or Creature Squad
Go beyond small figures and build characters as big as your child.
How kids use it:
-
Design one huge robot, dragon, or animal they can stand next to.
-
Or create a “team” of medium-sized characters with different colors and powers.
-
Use the builds for stories, battles, and cooperative pretend play.
Why 2+ sets help:
Life-size characters need thicker limbs and torsos to stay upright. Having multiple sets of extra large building blocks lets kids experiment with proportions, rebuild, and add accessories (shields, wings, tools) without stripping pieces from the main body.
6. Reading Nook Tunnel or Cozy Den
Combine building and relaxation by creating a space just for quiet time.
How kids use it:
-
Build a low tunnel they can crawl through to reach a cozy “den” at the end.
-
Add cushions, blankets, or a small lamp (placed safely outside the blocks).
-
Use color patterns to define the entrance, tunnel, and “quiet zone.”
Why 2+ sets help:
You’ll want enough jumbo building blocks for both the tunnel and the den to feel enclosed. Two or more sets let kids build high enough and wide enough that the structure feels special, not cramped.
7. Color-Blocked Feature Wall
Turn a blank wall into a giant canvas made out of blocks.
How kids use it:
-
Build a wide, flat “pixel wall” with patterns, letters, or simple images.
-
Change the design over time: hearts one week, stripes or initials the next.
-
Use the wall as a backdrop for photos, pretend stages, or puppet shows.
Why 2+ sets help:
A large wall needs lots of repeating colors. Extra sets of jumbo building blocks give you the volume to fill a big section of wall and still have pieces left over for small side builds.
