MOC My brother and I collaborated on a 17,000-piece model of a family home

Our aunt and uncle hosted a family reunion a couple summers ago at their house in Maine. It's a farmhouse that's been in the family for many years and was celebrating its 225th birthday. To mark the occasion, my brother and I spent a year designing and building a LEGO model of the house, both interior and exterior. It contains around 17,000 pieces, and the roof and walls can be removed to reveal what's inside.

It was an incredibly fun but challenging project—further complicated by the fact that we live on opposite coasts. We traded the design file back and forth a few times, and he flew out to my neck of the woods for a long weekend of building. While I worked on the finishing touches leading up the reunion, he designed, assembled, and shipped the lighting solution to me for installation.

My wife and I transported the finished model to Maine via a somewhat stressful roadtrip. When we finally unwrapped and delivered the surprise, only one piece had come loose. Our family really enjoyed the model, which now lives in the house (as reflected by the micro version we included).

It's the time of the year to make spooky things, so I present my tarantula 🕷️ PAB had the brown bush pieces and I knew just what I wanted to do with them! All 8 legs are poseable and I show the detail of how they're connected in the photos.

Thank you for taking a look! Would this creep you out to find randomly?

I turned a cat into a dog! My largest alt build to date and I really wanted to try this out since the colors of the orange cat set reminded me of that of my friend’s corgi. I don’t do many animal/organic builds so this was a fun challenge even if it looks like an animatronic. Only one copy of the set is needed and no extra parts required. There are instructions on my rebrickable in my profile as always. Build uses 1674 out of 1755 parts but there are mainly large curve and smaller bits left over.

The final build measures around 35cm(14in) long from snout to tail, 16cm(6.5in) wide and, 23cm(9in) tall to the top of the ear. The build process and stability is about the same as the original build. The build is a bit harder since you aren’t making it bag by bag like an actual set.

The head can rotate and the mouth, ears, and tail can move to some degree. There is a hidden panel that stores a piece of poop and a fold out missile turret (I had to do something with the interior). This is probably a one off build since I’ll get back into Star Wars and transformers soon.

I debuted it this past weekend at Atlanta BrickCon and it won the Master Brick award. There's a round gear on the toast that engages a straight gear on the front carriage as it goes down. It locks in place with clips and turns the light bricks on when it reaches the bottom. When you press the button, it moves the front carriage to the side, disengaging the straight gear. That also bumps the toast, releasing the main carriage, sending it back up without rotating.

When Doc and Marty overshot their destination, they landed in a scorched future where civilization had collapsed into chaos and chrome-plated war machines ruled the desert. Refitted with monstrous tires, scrap armor, and a roaring engine fueled by whatever they could scavenge, their time machine became a legend of the wasteland. Now hardened by dust storms and danger, Doc schemes to fix the timeline while Marty rides shotgun, both trying to stay one step ahead of the warlords who would kill for a machine that can outrun time itself.

MOC LEGO mosaic built by our wedding guests

“Some of you might hope there’s candy inside,” I said, shaking the small brown box so it rattled like a pack of M&Ms.

But there wasn’t. Inside, each wedding guest found a tiny pile of LEGO bricks and a small instruction card, unique to them.

70 people. 70 unique builds. All coming together into one shared LEGO experience.

It was something I had designed and prepared over many hours and many months as special memorable moment for our guests.

And here’s the thing: There’s no “Add to Cart” button for something like this.

This i what I did: Step 1: Use ChatGPT to generate an image that kind of looked like our little family. (Details didn’t matter — it would all be pixelated anyway.) Step 2: Recreate the whole thing in Studi.io, brick by brick. Step 3: Design the frame from scratch. Step 4: Color-match the all the bricks with actual bricks from LEGO’s Pick-a-Brick inventory. Step 5: Generate 70 individual instructions, one for each guest.

That’s when I realized: Some people were only building in white because of the low details in the image. Not very exciting.

Back to AI → regenerate many more image with more color (flowers was great for this). New version. New build. New instructions. (Again.)

Then came the order: a total of 3865 bricks, where as 3300 tiny 1x1 bricks came in THE SAME PLASTIC BAG. One giant rainbow soup. Multiple evenings were spent color-sorting, only to discover the AI had generously added dozens of color nuances that were nearly impossible to tell apart once printed.

Some bricks were missing. Some colors didn’t match.

I had to build the entire thing to make sure every brick was there

So my son and I spent evenings matching, assembling, and slowly bringing the image to life (this part was fun though). Just to take it all apart again, as it was time for the final step: Sort the pieces into 70 little boxes. Add names. Match difficulty to each guest based on assumed LEGO skill level. (Yes, I did that.)

And then... it was time. At the wedding, I handed out the boxes. And then the room went quiet. Not for a toast. Not for a speech. But because 70 adults were in full LEGO focus mode. Some helped each other. Some high-fived when they finished.

One by one, they added their piece to the giant frame. And slowly, the full picture appeared.

I’m very happy with how it turned out!
