The verdict

This is the fourth crack LEGO has taken at the Knight Bus, and it is comfortably the best one.

The new curved elements round off the roofline in a way the boxy 2019 version never managed, and lifting the top decks off to swing the little chandelier is a genuinely lovely party trick. It builds fast and easy, so if you want a puzzle it will not give you one, but as a shelf piece it earns its spot. Great for a Prisoner of Azkaban fan who wants the bus that actually looks like the bus.

Best for: Harry Potter fans who want the definitive Knight Bus without the old boxy roofline

The full review

What it is

The Knight Bus is one of those Harry Potter icons that LEGO keeps returning to, and this 2025 version is the one that finally clicks. The thing that got me is the roofline. Every previous bus, right back to 2004, ended up looking like a stack of purple boxes because the curved parts to soften those upper decks simply did not exist yet. Here they do, and the difference is night and day. The whole silhouette leans and bulges the way the film prop does, top-heavy and slightly ridiculous, and I love it for that. It measures about 15cm tall and sits beautifully at eye level on a shelf, that deep purple catching the light in a way photos never quite do justice.

The catch

I will be straight with you about the build, because it matters here. This is an easy set. It is rated 8+ and it feels aimed squarely there, with no clever half-stud offsets or SNOT sections to slow you down, so if you are an adult builder chasing a meaty afternoon you will be done before you have finished your coffee. There are a few honest gaps too. Even with the new curved pieces, the very rear of the bus does not close up as smoothly as the rest, and eagle-eyed fans have grumbled about a couple of visible seams back there. At 49.99 for 499 pieces it lands at a fair rate, roughly ten cents a part, though the interior, while sweet, thins out in places where a bit more furniture would have gone a long way.

Who it's for

So who should get this. If you are a Harry Potter collector, and especially if Prisoner of Azkaban is your book, this is an easy yes. It is the best Knight Bus LEGO has made and it displays wonderfully next to a Hogwarts set. If you are buying for a younger fan, the lift-off decks and swinging beds turn it into a proper play piece, which the older display-focused versions never really were. The people I would gently steer away are seasoned adult builders who want a challenge, because you will not find one in the bag. This is a set you buy for what it looks like finished, not for the hour it takes to get there, and on that score it delivers.

The parts story

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

Building this feels breezy in the best and slightly frustrating sense. The lower deck goes together in minutes, then you stack the two upper floors and clip them into place so they lift away again for interior access. That modular top is the smartest bit of engineering in the box, letting you swing the little chandelier and rock the beds without fighting the walls. It is the kind of build that a kid can finish proudly in an evening, which is clearly the point, even if it leaves a more practiced builder wanting one properly knotty section that never comes.

The stars here are the new curved slope and roof elements in dark purple, the parts that do all the heavy lifting on that iconic rounded shape and the reason this bus reads so much better than the 2019 one. The transparent window pieces are freshly tooled too, and there are lovely printed touches: a Daily Prophet tile reading Escape from Azkaban, and the ghostly Headless Nick as a trans element rather than a sticker. Add Padfoot the black dog, Harry's trunk, and the buildable lamppost, and you get a set where the small storytelling parts, not the part count, are where the value quietly sits.
