Lundby in Sweden was one of the earliest companies to manufacture Dolls Houses and all their products, being 1/16 scale will fit Triang houses. All the houses come ready assembled and pre-decorated, both inside and out and pre-wired to accept lights.
All of the miniature sets and figures are attractively gift boxed and made from sturdy plastic and are supplied with all the items shown (apart from the houses). Where lights are shown in the pictures (for instance, the kitchen units), they are included but they work off a 3.5v power supply.
The picture also shows the Basement and Garden extensions (the house is the top two stories)
