These LEGO Mocs channel my love of sci-fi and are evolutions of the original portal I built based on a forest scene. This is inspired by movies and games such as Doom and Stargate and it even features the Muppet collectable minifigures!
Why build portals? It’s something that’s always fascinated me. The idea of a wormhole or gateway to another dimension. And I think the original 1994 Stargate movie captured this beautifully!
The first LEGO Portal moc is an evolution of my original forest portal LEGO moc. But for this one, I wanted to do something a bit different and thought what if the portal had run into disrepair? So this features an overgrown scene with flowers, plants and vines that have taken over the portal causing barriers to fall and panels to fall off the portal. There’s even the helmet from a fallen traveller. Could the DOOM guy have visited?
For the second portal, I wanted to build something I could use in my LEGO City and I’ve had plans to build a Ninjago area for a while. So this has an Asian feel with a Japanese restaurant and a bright red torii leading to the lantern lines stairs that take you up to the portal itself.
And finally, the one I might be proudest of – although I love them all – is one based on one of my favourite games, Portal 2. That is set in the Aperture laboratories which have fallen into disarray since the fall of GLaDOS. I tried to capture some key features with the fallen tiles, half-built walls, and test buttons with their lines telling you how to activate them. An eerie white camera is watching you and recording what you do in the test. And just to finish the whole scene off, GLaDOS herself is lying on the floor with Dr. Bunsen Honeydew and Beaker from the muppets trying to repair her. What could possibly go wrong?
I really enjoyed making these and I’d love to know your thoughts on them. And also if you’d like me to show you how they are made!

📝 VIDEO FAQs
The portals are inspired by some of my favorite sci-fi and gaming universes! The first “run-down” portal has a heavy Stargate and Doom influence. The second features a Ninjago/Japanese temple aesthetic, and the third is a tribute to the Portal video game series, complete with a laboratory setting.
Mostly! I challenged myself to fit each scene onto a 16×16 baseplate. While the first two fit perfectly, the Portal game-inspired lab ended up going slightly over the edges because I felt the walls and extra details were essential to capturing that specific look.
The jungle-themed, overgrown portal is the oldest build. When I decided to revisit the concept for the other two, I slightly modified and evolved the portal design to give them a cleaner finish and different lighting features.
I thought it would be a fun twist to have Beaker and Professor Bunsen Honeydew from The Muppets working in the Aperture-style lab! They seem to be attempting some risky repairs on GLaDOS, which probably isn’t the best idea.
The fundamental structure of the portal itself is very similar across all three versions. I’m definitely open to doing a “How-To” video! Let me know in the comments which style you’d like to see me break down first.
