At Atlanta Brick Con 2026, I talked with builder Ben Sliker (Benderbuilds on Instagram) about his massive LEGO Ghostbusters Firehouse MOC—roughly 22,000 pieces and built to the scale of the Ecto-1, so it’s a bit bigger than standard minifigure scale. Ben never got a chance to buy the official Firehouse set before it became astronomically expensive, so he did what AFOLs do best: built an even bigger version that costs even more, and packed it with references from both Ghostbusters and Ghostbusters II. One of the showstoppers is the exploding “energy beam” blasting out the roof—an idea someone suggested early on that took Ben nearly a year to engineer. The whole building is constructed in floors that slide in from the top, and the lighting (from Light My Bricks) had to be wired as each level dropped into place, with a controller in the basement to switch between modes. We also go floor-by-floor through the interior: Janine and Peter’s desks, the garage space that actually fits the car, the containment unit and “turn the grid off” moment, the living quarters and toaster test, the photo lab from the second movie, plus custom rooms like proton pack testing and Slimer’s attic mess. Ben also breaks down exterior techniques like wrapping tiled detail using SNOT bricks, and he shares how well the build survived a four-hour trailer trip to the convention.
