About LEGO LEGO® Ideas Home Alone

Recreate the iconic McCallister house from the beloved Christmas film with 3,957 pieces that form a detailed, interactive model. The house features opening walls and roof sections for easy access to meticulously crafted interior rooms that recreate memorable scenes from the movie.

The set includes ingenious interactive elements that bring key film moments to life. Swinging paint cans recreate Kevin's booby traps, while a basement furnace lights up using an included LR41 battery and LEGO light brick. A working lever mechanism allows Kevin's minifigure to slide down the stairs on his sled, and a functional zip line connects the house to the included tree house for dramatic escapes.

What's Included

Five minifigures represent the main characters: Kevin McCallister, Kate McCallister, Harry, Marv and 'Old Man' Marley. The set also builds the distinctive tree house and the crooks' van, complete with authentic details that reference specific scenes from the film. Each room in the house contains carefully designed elements that will spark recognition among fans of the movie.

Build Experience

The 3,957 pieces are organised into 24 numbered bags, with the building sequence following the movie's plot progression. The completed house measures 27 cm high, 34 cm wide and 37 cm deep, making it a substantial display piece. An illustrated booklet provides background on both the original fan creator and the LEGO design team who developed this Ideas set.
