9. Build something entirely custom from non-Halloween LEGO sets
Source: Reddit
Don’t limit yourself to pre-made Halloween sets when you can create your own eerie masterpiece. Get inspired by collectors who’ve taken non-Halloween LEGO sets—like the tranquil Bonsai Tree—and transformed them into spooky decor.
Turn delicate blossoms into blood-red flowers or add tiny spiders to the branches. And once you’ve Frankenstein’d your build, a display case will ensure your one-of-a-kind creation stands out, giving it the spotlight it deserves while keeping it in perfect condition for future Halloweens.
10. Create interactive LEGO Halloween build ideas, like a haunted maze or mini roller coaster
Up the Halloween ante by building interactive LEGO sets like a haunted maze or mini roller coaster to spook your guests and add an extra layer of fun to your display.
This is where LEGO gets really fun…. and spooky. Add tiny skeletons riding through a creepy course or ghosts popping up as LEGO Minifigures trying to escape the maze’s twists and turns.
11. Awaken the dead with LEGO graveyard scenes
Summon the spirits and bring your Halloween setup to life with a LEGO graveyard scene. Build eerie tombstones, crumbling mausoleums and skeletons crawling out of the ground—every creepy detail adds to the fun.
Use a display case or stand to keep your graveyard perfectly haunted (and perfectly tidy). It will take your scene to the next level and ensure that those fragile gravestones don’t tip over at the slightest bump.
12. Construct a haunted forest with LEGO trees and spooky creatures
Display Case for LEGO® Harry Potter™ Buckbeak (76427) £54.99
Transform your LEGO collection into a haunted forest with towering trees and creepy creatures. With twisted branches, ghostly owls or lurking wolves, this woodland wonderland can quickly become your Halloween centrepiece.
Toss in a few LEGO bats flying overhead, and you’ve got yourself an eerie scene straight out of a dark fairy tale. Make your haunted forest even more enchanting with a Wicked Brick display stand for a spooky setup that commands attention, with every creepy critter in perfect view.
13. Create a potion lab with LEGO for witches and wizards
Display case for LEGO® Harry Potter: Gringotts™ Wizarding Bank – Collectors' Edition (76417) £166.99
Ready to brew up some LEGO magic? Create a potion lab fit for witches and wizards with bubbling cauldrons, glowing potions and spooky spellbooks.
Add some LEGO Minifigures of witches concocting their latest brew, and let your imagination run wild with all the spooky ingredients you can think of—frog legs, anyone?
14. Design a Halloween parade with LEGO floats and mini-figures
Turn your LEGO Halloween into a full-on spectacle by designing a Halloween parade. Create fun and spooky floats decked out with pumpkins, skeletons and bats pulled by creepy Minifigures in costumes, each adding to the festive chaos.
A display stand will help keep your parade perfectly organised, ensuring it's the talk of the town (or at least the LEGO block), with every float in position and ready to roll.
15. Recreate iconic scenes from scary movies with LEGO
If you're a horror movie buff, bring your favourite chilling scenes to life with LEGO. Recreate the terrifying moment from The Shining when Jack Nicholson's character busts through the door, or build your own LEGO version of the spooky house from The Exorcist.
Adding a LEGO twist to classic scary moments is a fun and clever way to make your Halloween decor more unique—not to mention it’s a great challenge.
And if you want to display these horror icons with cinematic flair to boot, a premium acrylic case will protect them like a true collector's piece while keeping the terror front and centre.
16. Build Halloween-themed LEGO spaceships and alien creatures
Limited Edition Wall Mounted Display Stand for LEGO® Guardians of the Galaxy: The Milano (76286) £69.99
Take your Halloween beyond the stars by building Halloween-themed LEGO spaceships and alien creatures.
Give your intergalactic fleet a spooky twist with black-and-orange colour schemes, glowing lights and some alien Minifigures, or stand out like a Sith Lord with a Star Wars Darth Vader helmet.
From UFOs with pumpkin-shaped cockpits to extraterrestrial invaders ready to crash the party, the possibilities are endless. Ensure your spooky spacecraft stays securely grounded (or prepared for takeoff) with a stylish stand.
17. Create a witch’s cottage with LEGO
Display case for LEGO® Ideas Disney Hocus Pocus: Sanderson Sisters' Cottage (21341) £82.99
