We Build The Massive, Multi-Set LEGO Harry Potter Hogwarts Castle, Currently In Progress

In 2024, LEGO began the most ambitious build project the company has ever attempted: a fully realized, minifigure-scale re-creation of Hogwarts Castle, made famous by the Harry Potter franchise. A single set of this size and scope would be impractically large and prohibitively expensive. So instead, LEGO is releasing numerous smaller LEGO Harry Potter sets that, when combined, will form the full castle. It's a truly massive undertaking.

This is an ongoing project; LEGO has not announced the end date for the final set. But based on their current pace, it's going to be years before the project finally wraps. We've been building the LEGO Hogwarts Castle since it launched, and we will continue building and adding to it until it's complete. If you would like to do the same? it's not too late to start, although LEGO has retired some key sets at the end of 2025.

Here is every set released so far that comprises the modular LEGO Hogwarts Castle, currently in progress as of August 2026. We've included a grand piece count and price count at the bottom, which we will update as the castle continues to grow. Lastly, we took and included some photos of the castle as it currently stands, so you can see its current progression.

LEGO Harry Potter: Hogwarts Castle Sets

These are the sets you'll need to buy if you want to create your own enormous LEGO version of Hogwarts Castle. But these are just the sets released to date – more will be added in the future.

Hogwarts Castle: Owlery (Retired)

The Owlery is the first component of the Hogwarts Castle. If you're looking to cut a corner or two and save on costs, you might start with this one, because it's an independent structure apart from the main building. It has winter-themed, snow-capped spires, so if you're after aesthetic consistency, you might also want to swap out a few pieces to make the Owlery match seasons with the rest of the castle.

Hogwarts Castle: Boathouse (Retired)

Both the Boathouse and the Owlery share the same gray-colored hue on their spires. Back in 2024, this led many LEGO fans to speculate that these sets marked the beginning of a new Hogwarts Castle, even though it hadn't been officially announced yet. The Boathouse includes two small wooden boats, so you can recreate Harry's first-year arrival at Hogwarts.

Hogwarts Castle: Potions Class (Retired)

This is the first Hogwarts classroom set, which can swap in to replace another room in the castle. To use an example: The Great Hall comes with the girl's bathroom in the dungeon, where the troll attacks Hermione in the first book/movie. It's nice looking diorama, but it's extremely scene specific, and it doesn't really fit in with the rest of the castle. So, if you want to, you can swap out the troll scene with Professor Snape's Potions Classroom, which is a lot more detailed and colorful, and contains a wider range of roleplay opportunities. If you don't get the Potions Classroom, it's not going to look, at least outwardly, like something's missing. But still, it's hard to imagine Hogwarts without it.

Hogwarts Castle: The Great Hall (Retired)

The first major 'essential' building block in the Hogwarts Castle, the Great Hall includes the eponymous Hall – where the Sorting Ceremonies and Start and End-of-Term Feasts take place – and three additional rooms: the girl's bathroom where the troll attacked Hermione; a narrow corridor; and the Hufflepuff Common Room. The Great Hall connects to the Boathouse at the bottom of the outer stairwell; connects to the Main Tower at its side; and can swap its bathroom with the Potions Classroom. We built and photographed this one at the time of its launch.

Hogwarts Castle: Dueling Club (Retired)

This set recreates the Dueling Club scene from Chamber of Secrets, in which Draco conjures a snake and Harry uses Parseltongue to stop it from attacking Justin Finch-Fletchley. There's a gimmicked floor in the table that makes the minifigures fly backwards off of it. If you want, you can swap out the house tables in the Great Hall with the Dueling Club table. It's a fun alternative, but overall inessential to the larger castle, if that's what you're going for.

Hogwarts Castle: Charms Class

Professor Flitwick's Charms Classroom lets you recreate the Wingardium Leviosa scene from the first book/movie ("It's Levi-O-sa! Not Levio-SA."). The Professor Flitwick minifigure has his original movie appearance, when the filmmakers leaned into his goblin hertitage. The Charms Classroom slots into the Flying Lessons set, and can swap with the Quidditch equipment room.

Hogwarts Castle: Flying Lessons

On the exterior, this set depicts the scene where Harry rides a broom for the first time (it even includes a minifigure of Madame Hooch). But on the interior, this is a Professor McGonagall-centric set. It includes the aforementioned Quidditch equipment room, but it also contains McGonagall's office and McGonagall's Transfiguration classroom. The Flying Lessons set doesn't connect to any of the current sets; it'll fit in later, once we have more of the Castle completed.

Hogwarts Castle: Herbology Class

The Herbology Classroom includes a rare Professor Sprout minifigure, plus Hermione and Neville in their greenhouse smocks and gloves. The greenhouse feels appropriately overgrown and busy, with three mandrake plants and accompanying earmuff accessories. It is a freestanding structure from the larger Hogwarts Castle, although unlike the Owlery, it'll be in close proximity to it.

Hogwarts Castle: The Main Tower

The second major Hogwarts Castle set, the Main Tower connects directly to the Great Hall on its right side. And taken together (see more photos below), you really get a sense of size and scope. The interior contains three of the rooms from the Sorcerer's Stone trials: the Devil's Snare room, the Flying Keys room, and the Chess Set room. One floor up is Fluffy's room and a narrow corridor. One floor up from that is the Gryffindor Common Room. And then the actual Main Tower contains three staircases (two of them rotate), Dumbledore's office, and a secret room containing the Mirror of Erised. We built and photographed this set at launch.

Hogwarts Castle: Room of Requirement

This may end up being the rarest set in the whole modular collection. This re-creation of the Room of Requirement, as seen in Harry Potter and the Deathly Hallows, includes hammocks and sleeping arrangements for Dumbledore's Army members. It comes with a single minifigure of Neville Longbottom.

The above price of $19.99 is what LEGO listed on their website. It was, however, never on sale by itself; rather, it was a gift-with-purchase for anyone who bought $130 worth of Harry Potter LEGO in the first week of September 2025. Your best bet is the secondary market, but don't break the bank over it; it's an an optional classroom that slots into the Main Tower, rather than a standing structure by itself.

Hogwarts Castle: Hospital Wing

A mandatory set for the full castle build, the Hospital Wing connects to the Main Tower and wraps around its right hand side. It contains far more than Madam Pomfrey's triage center, however; it also contains the Ravenclaw common room and Professor Lupin's Defense Against the Dark Arts classroom, complete with a Boggart wardrobe and phonograph.

Hogwarts Castle: Sorting Hat Ceremony

This set reimagines the Sorting Hat Ceremony as a wheel-spinning game, and it includes the hourglasses of rubies, diamonds, sapphires, and emeralds that tally the annual house points. It is designed to fit into the Great Hall as an add-on option, similar to the retired Dueling Club set. For fans looking to build the full castle, it's fun but ultimately inessential.

Hogwarts Castle: East Wing

An essential component to the overall build, the East Wing connects to both the Great Hall and the Main Tower via bridges. This set contains the Slytherin common room and Moaning Myrtle's batroom; go down a slide, and you'll wind up in the Chamber of Secrets. In addition to the massive, sculpted head of Salazar Sytherin, the Chamber of Secrets also features a scary-looking basilisk, which threatens to attack and kill all Muggle-born. The set includes 13 minifigures in all.

For photos of the entire Hogwarts Castle build so far, see below.

What's The Current Total Piece Count?

As of August 2026, the current total piece count stands at 9,778.

What's The Current Total Price?

As of August 2026, the current total price stands at $1162.87.

How Do You Put This All Together?

In the below photo, I've put together the entire castle, as of August 2026.

I've taken some creative license with the placement of the Hospital Wing. According to LEGO, it's supposed to form a courtyard at a right angle with the Main Tower. But it's impossible to see it, all the way back there, when you're looking at the castle from the front. I could display the castle from a different angle. But if I do this, it reveals the open backs of the models, which breaks the illusion.

So, I've decided to move the Hospital Wing to the area on the right side of the East Wing, directly above where I placed the Greenhouse. If the LEGO designers eventually put the Divination Tower or the Bell Towers in this area, I'll have to move the Hospital Wing again. But until then, I like how its current placement gives the castle better balance and makes it more physically imposing.

I've placed the Flying Lessons and the Owlery on the right side of the castle as well.

What's Next?

Just prior to releasing the Owlery, LEGO released an architectural build of Hogwarts Castle in miniature form. It has the same grey spires as the modular castle, and because of its timing, my theory is that it is a rough blueprint for how the final castle will look. Above, I've circled the parts of the modular castle that have been released. So, as you can see, we have about one-third of the final building to go.

Details

Still, some LEGO fans have theorized that the Hogwarts Castle is complete. The reasoning is that the old 6,020-piece microscale build stopped at the East Wing and never built beyond that.

In May 2026, I reached out to LEGO and asked them if the East Wing marked the end of the castle build. The response I got back was that at the time, they weren't able to share information regarding that.

It definitely feels like the designers could go further if they wanted to. The three most notable, missing parts of the castle are the Astronomy Tower, the Clock Tower, and the Bell Towers. We are almost certainly not getting the Clock Tower because of its canonical placement behind the Main Tower. The Bell Towers are a slight possibility. But the Astronomy Tower would be the most likely (and desirable) of the three. The tallest structure in Hogwarts, the Astronomy Tower is also where Dumbledore and Draco have their climactic confrontation in Book Six.

Update: Mini-Castle Teaser?

LEGO announced that a new Mini Hogwarts Castle (seen above) will launch in late August. You'll notice that this build, like the prior mini build, has an Astronomy Tower. The specifications for the set also mention the Astronomy Tower as a key location:

"Kids can relive their favorite wizarding scenes as they build microscale versions of The Great Hall, Main Tower, East Wing and the Astronomy Tower."

We still have no official word, one way or the other, if the modular castle is officially finished. But they've already released the other major parts of the build (ie. The Great Hall, Main Tower, and East Wing), so perhaps the Astronomy Tower is next? Or maybe it's wishful thinking.

We'll have a better idea when LEGO announces the next wave of Potter sets. If there are no Hogwarts Castle sets amongst them, we can assume the castle is finished. But let's hope not.
