This LEGO Creator 3in1 Cozy House (31139) building toy set is designed for kids aged 8 and above. It offers three distinct building experiences: a family toy house with four rooms (kitchen, living room, master bedroom, and child's bedroom) and a garden terrace, a three-floor canal house with an attic office, art gallery, and café, or a vacation lake house on the water with a boat. The family and lake house models can be opened in the middle, while the canal house's top floor can be removed and added to the back. Each model can be adjusted and played with in two positions. The set includes three minifigures (two adults and one child) whose clothes and hair can be swapped to create different characters. The family house comes with terrace furniture and a letterbox, the canal house includes a dog and two toy boats, and the lake house features a fire pit and a boat. The set contains 808 pieces and is made of plastic. The color is Multicolor.
