Top Picks for 2025
If you’re buying one set this year, make it one of these.
LEGO Harry Potter Hogwarts Castle 71043
The ultimate Harry Potter LEGO set. Over 6,000 pieces. Micro-scale Hogwarts with incredible detail – the Great Hall, the Chamber of Secrets, Dumbledore’s office, the Whomping Willow. This is for serious fans with display space and patience. Building it took us three weekends.
LEGO Harry Potter Malfoy Manor 76453
New for 2025. The first official Malfoy Manor set. 1,601 pieces of dark gothic architecture from Deathly Hallows. Voldemort, Bellatrix, the whole Death Eater crew. This is for older fans who appreciate the darker side of the series.
LEGO Harry Potter Hogwarts Express 75955
Platform 9 3/4 with the iconic red train. The moving brick wall entrance is clever. Six minifigures including a Dementor. This was our first set and it’s still on display. A perfect starting point for any collection.
New 2024-2025 Modular System
LEGO redesigned Hogwarts from scratch in 2024. These sets connect together to build a new minifigure-scale castle. The Main Tower is the centerpiece.
Hogwarts Castle: The Main Tower 76454
The biggest 2025 release. 2,135 pieces across six floors. Dumbledore’s office, the Grand Staircase, and more. This is the heart of the new modular system. If you’re building the new Hogwarts, start here.
Hagrid’s Hut: An Unexpected Visit 76428
The 2024 Hagrid’s Hut with 896 pieces. Opens up to show the interior with oversized furniture and includes Fang. Much better detail than older versions, and it connects to the modular system.
Hogwarts Castle Boathouse 76426
Where first-years arrive, with 350 pieces including boats and Hagrid with his lantern. A small, quick build with good detail that serves as an entry point for the modular system.

The Owlery with 364 pieces, featuring a rotating owl perch mechanism with multiple owls including Hedwig. The Cho Chang minifigure is exclusive to this set.
Hogwarts Castle: Potions Class 76431
Snape’s dungeon classroom with 397 pieces. Potion bottles, cauldrons, and the dark atmosphere done right as part of the modular system.
Best for Kids
Smaller sets under $50 that work well for ages 6-10 or as gifts, with quick builds that won’t frustrate younger builders.
Hogwarts: Charms Class 76442
Best value in the 2025 lineup. Under $20 for Professor Flitwick’s classroom. 204 pieces. The floating feather for Wingardium Leviosa is a nice touch. Perfect starter set.
Hogwarts: Dueling Club 76441
The dueling scene from Chamber of Secrets for under $25. Harry, Draco, Snape, and Lockhart minifigures. A quick build that’s fun for play and good for younger kids.
Knight Bus Adventure 76446

Hogwarts: Fluffy Encounter 76387
The three-headed dog guarding the trapdoor, from the 20th anniversary collection. Includes a golden Hermione minifigure. Small set, but the three-headed Fluffy is impressive for kids.
Best for Adults & Collectors

Diagon Alley 75978
The full-size Diagon Alley. 5,544 pieces. Ollivanders, Gringotts, Weasleys’ Wizard Wheezes – all the shops. 14 minifigures. This is a statement piece. Expensive but worth it for collectors.
Diagon Alley Microscale 76439
New for 2025, the entire Diagon Alley in microscale with 2,750 pieces for $200. Same approach as the 2018 Hogwarts Castle. A display piece rather than a playset, with all the shops in miniature.
Talking Sorting Hat 76429

4 Privet Drive 75968

LEGO typically retires sets after 2-3 years. The 2021 20th anniversary sets (Chamber of Secrets, Fluffy Encounter, Polyjuice Potion) are likely retiring soon. The 2020 sets like 4 Privet Drive and Astronomy Tower may already be harder to find at retail price. Buy these if you want them – prices go up after retirement.

LEGO releases new Harry Potter sets every year, typically in January and June waves. Summer 2025 is expected to bring Herbology Class, Dumbledore’s Phoenix, and an Aunt Marge’s Visit set. 2026 sets haven’t been announced yet but expect more additions to the modular Hogwarts system.
Both. Sets marked 18+ (Hogwarts Castle, Diagon Alley, Talking Sorting Hat) are designed for adult collectors with complex builds and display-focused designs. Most other sets are designed for ages 7-12 but are enjoyable for adults too. The Hogwarts Moment book sets work well for ages 8+.
