A few days ago, the LEGO Stranger Things Castle Byers building event was held at LEGO Brand Stores around the US. If you remember, the build was originally at the Flatiron and Leicester flagship stores when The Upside Down (75810) was released.
The build is pretty straightforward with it just stacking bricks. The outer part of it uses some brown antenna pieces to represent the sticks that are on the outside of the castle. There’s a flag for the cloth used as the entrance but the interior is empty. I do like the addition of the tire sitting on the outside of it. The main thing here are the exclusive stickers for Castle Byers and the All Friends Welcome sign. These were given after you finished the build but if you’re building it with your own bricks, there are some available on eBay.
Below is the parts list for Castle Byers as well as updated scans of the building instructions with better color quality. I do appreciate LEGO doing this building event for the rest of the US as many fans were pretty vocal about having it at only two stores around the world. I do feel bad for those who paid $100+ on the secondary market to get it though.
Update: My friend sent over scans of the stickers if you want to print them out on your own.
