At Brickworld Indy 2026, I (Joshua Hanlon from Beyond the Brick) sat down with Caleb Bell from IndyLUG to tour their massive collaborative layout: the “Galactic Galleria,” an alien shopping mall built by about 15 different builders. Caleb and his friend Nick Griffin handled a lot of the core infrastructure—facades, floors, back wall, and rockwork—so other builders could create individual storefront modules that slot right into the mall. The result is exactly what I love about collaborative LEGO MOCs: a shared framework that still leaves tons of room for each builder’s personality and humor. We walk shop-by-shop through the space-mall twists on familiar Earth ideas—like a leaky bathroom spilling mysterious green slime, an “earth antiquities” shop selling ordinary human stuff to curious aliens, an ice cream store with gross-sounding alien flavors, and a glowing transparent display enhanced with lighting. Caleb also shows off his own Rock Raiders-inspired “Bass Pro Ships,” a “Build a Martian” customization shop, and a classic-feeling pizzeria. One of the biggest takeaways here is how much planning went into the behind-the-scenes engineering: Nick used Studio to design the standardized structure, they held group build parties to assemble it, and they even hid Technic holes to route wiring for lights and tiny screens. They’re already dreaming about expanding the spaceship parking lot—maybe onto floating asteroids with trams and ferries to bring minifigs to the mall.
