Description
Small but versatile
At 318 pieces this is the smallest set in the group, yet its 69 part types give a respectable variety. That is enough for a small house or a single vehicle, or for two or three tiny models side by side. Because the box is manageable, it suits a first building day with children, with no sprawling piles of bricks covering the whole table or leaving anyone overwhelmed by the choice. The space needed stays small too, so the set can be built comfortably on a kitchen table or desk.
Three minifigs
The three minifigs bring the models to life. They can live in a house, drive a car or act out a story together. Each figure needs little space, yet even a simple building looks inhabited with one inside. If you own more figures, they combine happily with this set. That lets you expand the box step by step into a small town in which everyone has a place.
Four main colours
Red, blue, black and yellow define the set. The selection looks clear and calm at once, especially if you use two or three colours per model. A red wall under a black roof, a yellow vehicle on blue wheels: such contrasts work immediately. That makes the box a good starting point and a handy addition to collections where these colours are common anyway. If you prefer a calmer look, simply leave one of the four colours out.
Counting parts, building further
To find out exactly what is in the box, use the parts list on this page. It shows every type with its quantity, so you can spot gaps in a used copy. The “What can I build?” tool on this site also shows which models can be put together from all your parts, even when this set is only one part of your collection. It is also useful if you only need a few part types for other projects.
