LEGO Harry Potter 76430 Hogwarts Castle Owlery

A slim, tall tower about 36 cm high with Hedwig, Cho Chang and Argus Filch, which makes it one of the easiest ways to add height to the castle's edge without a big spend. It cost £39.99 for 364 pieces and left sale at the end of 2025, so it is now a hunt through other sellers; it is worth the effort if your castle looks flat at one end.
