The verdict

If Christmas at your place involves the whole family and you want a build you can all do at once, this one was made for you.

It splits into 24 bags like an advent calendar, so up to six people can build side by side using the LEGO Builder app. Just know the price is steep and building it solo gets repetitive fast, so this really shines as a group activity rather than a quiet evening for one.

Best for: families who want a shared December building tradition

The full review

What it is

Here's the pitch behind this LEGO® set: it's a 3,171-piece Christmas tree that stands about 45cm to the top of the star, and the whole thing is designed to be built together, taken apart, and rebuilt every single Christmas. The tree sits on a base with opening panels that hide little rooms inside, and there's a sleigh, a reindeer, a snowman, brick-built plushies, and a genuinely great cast of characters. LEGO leaned hard into the family angle here. The box splits into 24 numbered bags like an advent calendar, and using the LEGO Builder app up to six people can build different sections at the same time. If your December already has a house full of people looking for something to do, that's a lovely idea and it's the whole reason this set exists.

The catch

Now the honest part. This is not a cheap set. At $329.99 it's one of the pricier seasonal releases, and while the per-piece cost works out to a reasonable 10 cents or so, you're paying for a decoration first and a display model second. The bigger catch is the build itself if you're going solo. Reviewers were pretty united on this: alone, it's repetitive, and those 96 new leaf pieces in particular become a bit of a slog when you're the only pair of hands. The set almost punishes you for building it the traditional way, because the fun is baked into the group experience. There's also the storage reality to consider. It's brilliant that everything packs back into the box on boxing day, but that also means this lives in a cupboard for eleven months of the year rather than on permanent display.

Who it's for

So who should grab it? Families with kids old enough for the 9+ build, or any household that wants a shared Christmas tradition instead of one more thing on a shelf. If that's you, the combination of a good-looking tree, a top-tier minifig lineup, and the build-together gimmick is honestly a lovely way to spend the run-up to Christmas. Who should skip it? Solo adult builders chasing a satisfying quiet build, and anyone who wants a set that stays out on display all year. It landed a modest 3.6 out of 5 on Brickset, and that feels about right: a set that's exactly as good as your reason for buying it. Buy it for the people you'll build it with, not for the model alone.

The parts story

What the build is actually like, and the pieces worth knowing about.

The build breaks into 24 bags, one per advent day, and that structure tells you everything about the pacing. Solo, it's steady and a little samey, with a lot of the same leafwork repeated up the tree. Where it comes alive is splitting those bags between builders, because different people can be assembling the interior rooms, the base, and the tree branches all at once. And those interiors are the best bit: there's a workshop, a kitchen, an arcade break room, and Santa's little control room tucked behind the opening panels, all packed with the kind of tiny detail you'll keep finding for weeks.

For parts nerds there's real stuff here. The headline is a brand new element, the Plant Leaf 6 x 8 x 1 2/3, which shows up nearly 96 times in dark green and gives the tree its more realistic shape (expect to see it turn up in future Botanical sets). There are four new prints, including a snowman pillow plush with a carrot nose, a green and yellow tracking monitor panel, and a blocky cat face tile. On top of that you get 13 recolors, from dark green Technic beams to pearl gold pins and dark red curved bricks, plus six spiked maces in opal trans-clear, which is the most that part has ever appeared in a single set. The minifigs carry a lot of the value too: Santa with dual-molded legs, Mrs. Claus with an exclusive printed dress, and a 4-armed robotic elf with a brand new torso. At roughly 10 cents a piece, that's fair value for what you're getting.
