Here’s another delightfully unexpected news coming from the LEGO Harry Potter front. In what seems to be an accidental listing over at LEGO Shop@Home Japan portal (the said listing has been taken down as of this posting), eagle-eyed fans caught glimpse of what seems to be this year’s largest LEGO HP set. Coming in at more than 5,000 pieces, the new LEGO Harry Potter Diagon Alley (75978) set is slated to arrive soon.

If you recall back in 2011, LEGO has released it’s first, should I say, comprehensive rendition of the famous Harry Potter marketplace coming in at 2,025 pieces. This LEGO Harry Potter Diagon Alley (10217) consists of smaller brick builds of famous stores such as Ollivander’s, Borgin and Burke’s, and Gringott’s Bank. As impressive as this direct-to-consumer (D2C) set back during that year, there are still plenty of fascinating shops that we wish could have been included.
And after 9 years since its debut, it looks like we will be having our next LEGO version of this magical marketplace with an impressive piece count of 5,544 pieces. We do not have official images yet of this set understandably, but based on its now removed listing, we can expect the following shops to be included in this set: Ollivanders Wand Shop, Flourish & Blotts bookseller, Scribbulus Writing Implements, Quality Quidditch Supplies, Florean Fortescue’s Ice Cream Parlor, The Daily Prophet, and my personal favorite Weasleys’ Wizard Wheezes. Though it would be nice if LEGO included a rehashed version of Gringot’s for good measure, I think with 7 shops included in this modular set, I certainly don’t have any qualms against it.
Here’s what we can find from the now-taken down description of the new LEGO Harry Potter Diagon Alley (75978). This set is expected to have a whopping price tag of $399.99 and is intended for builders 16 years old and above. I wouldn’t be surprised though if LEGO will opt to include it under its 18+ collection given its piece count and retail price. Be sure to be on the lookout for LEGO’s official announcement which may happen any time soon. Hopefully, the release of this new brick version of Diagon Alley will be released alongside that of the upcoming LEGO Harry Potter Collectible Minifigure Series 2 (71028) coming in September.
Special thanks also to The Brick Fan for the heads up.
