Editor of Brick by Brick, adult LEGO fan and collector
I'm Jonny Utah, the editor behind Brick by Brick. I'm an adult LEGO fan who built this site to answer the questions I kept running into as a collector: which set is worth the money, whether a retiring set is likely to hold its value, and what to buy for someone else.
Every guide and comparison here starts from the same sources: our catalog of official sets for piece counts, years and inventories; current market pricing; and community feedback from Reddit and YouTube. Where a page uses AI-assisted summaries it says so, and the numbers on it come from that data, not from the model. I don't build every set I write about, and the site never claims otherwise. When an article draws on hands-on experience with a set, it says so in the text.
I also build the tools on this site, from BlockTalk to the price-per-piece and display-space calculators, because I wanted them for my own collection. The full methodology is on the How We Review page.

The Ultimate Collector Series Death Star (75419) and the Icons Barad-dûr (10333) are both still on sale and both packed with interior scenes. Here is how the two big 18+ villain fortresses compare, from LEGO's own descriptions, and which suits your shelf and your films.
LEGO's Star Wars Diorama Collection ran to five sets in 2022 and 2023, and all of them have retired. Here is how the three best known, Dagobah, the Death Star Trench Run and the Emperor's Throne Room, compare, what to check when buying one second hand, and the current display sets that fill the same shelf.
Only five LEGO Star Wars helmets are still sold new in 2026, and three of them leave on December 31. Here is which to buy, which have retired, including Darth Vader, and how the series fits on a shelf.
The LEGO Gringotts Wizarding Bank Collectors' Edition left LEGO's range in July 2026, while the Hogsmeade Village Collectors' Edition, built to the same scale, is on sale until the end of 2027. Here is how the two big 18+ Harry Potter locations compare and which to buy now.
LEGO's connecting Hogwarts Castle sets have changed. The 2018 to 2022 modules have all retired, and the 2024 collection's Great Hall left in July 2026. Here is what is on sale now, where to start, and which two sets leave at the end of 2026.
The two great LEGO Harry Potter display builds are no longer an even choice. The Hogwarts Express Collectors Edition (76405) retired at the end of 2024, while the Hogwarts Castle (71043) is still sold new. Here is how they compare and what to buy instead of the train.
A bigger LEGO budget buys a bigger set, not a cheaper price per piece. Across the 835 sets our catalog lists as on sale, the median price per piece barely moves from under $50 to $200 and up; what changes is the size of the build and who it is designed for. Here is what each budget buys, with picks.
BrickHeadz are brick-built display figures with a big cube head, sold on their own. Minifigures are the small figures that come in most LEGO sets and in blind-packed series. Here is how they differ, how many of each exist in our catalog, and which to collect.
Most children move from DUPLO to regular LEGO between about 4 and 6. This guide covers what each system is for, exactly how DUPLO and standard bricks connect, the signs a child is ready, and the 4+ sets on sale now that bridge the gap.
The Flower Bouquet is the garden-flower original and the Wildflower Bouquet is the meadow follow-up. They share almost no flowers, LEGO designed them to combine, neither comes with a vase, and only one of them is expected to stay on sale.
Four LEGO flower sets side by side. The Orchid comes with its own pot, the Succulents with nine small containers, and the two bouquets need a vase of your own. Here is what each one looks like on display, who each suits, and which one is expected to leave LEGO's range at the end of 2026.
Two of these three modular buildings have left LEGO's shelves. The Boutique Hotel and the Jazz Club retired at the end of 2025, while the Natural History Museum is expected to stay on sale until the end of 2027. What each one contains, how to buy the retired two, and which modulars you can still buy new.
