One of the more impressive and enduring LEGO sets for adults (well, ages 16+, anyway) is the LEGO Ideas Tree House. It's a massive three-unit tree house you can build with either green leaves or yellow leaves for an autumnal feel. It normally rings in at $250, but it's on sale for $75 off for Prime Day. Grab it before it's gone.

Red Bull may be losing its way in this year’s F1 Championship, but this Lego Speed Champions RBR set should prove a winner whatever happens on track. It’s based on the 2024 RB20 car – so the one that Max Verstappen drove to the title – and has 251 pieces, plus a Minifigure driver. Christian Horner not included (sorry, Christian).

The only real issue with a Lego habit is that it gets expensive fast, no matter if you're trying to recreate the entirety of Middle Earth with supersized Lord of the Rings sets or kitting out your model Formula 1 racing team at home.
