LEGO 2026 rumours: Harry Potter, Classic and Gabby’s Dollhouse

The first word on three new LEGO 2026 sets has surfaced, across Harry Potter, Classic and Gabby’s Dollhouse – including a mystery 1,200-piece Wizarding World model…

While we’ve got a pretty good picture of the LEGO Harry Potter 2026 slate so far, bricky_news reports that 76478 will also be part of this year’s line-up, coming in at 1,182 pieces for €129.99. That product number has not yet appeared on any other rumoured lists of LEGO Harry Potter sets for 2026, and while there’s not much more to go on at this point, the price-per-piece ratio would suit a minifigure-driven playset.

Also included in this latest batch of rumours are 11045 Colourful Creative Bricks, a LEGO Classic set that’s said to cost €49.99 and hit shelves in June, and 11212 Kitty Fairy Garden’s House, a Gabby’s Dollhouse model that will reportedly debut in August for €14.99. Classic as a theme has yet to put in an appearance in 2026, despite dropping six new sets in the first half of 2025.

Gabby’s Dollhouse, meanwhile, has just one set to its name so far this year in 11215 Gabby's Brick-Built Cat Friends. That 324-piece 6+ set is the theme’s first to target builders older than 4+, presumably hoping to retain the attention of young fans who hopped on board in 2023 or 2024, so it’ll be interesting to see where it goes next this summer.

That’s assuming these details prove to be on the money – for now, take any rumoured information with a pinch of salt. You can find a complete list of rumoured LEGO 2026 sets here.
