This is the costliest toy and certainly the priciest dollhouse ever. The Astolat Dollhouse Castle is worth a whopping $8.5 million because of its best creativity, engineering, architecture, and sculpting. It has a pool, gym, many floors, and 29 rooms. Also, there is a basement, wine cellar, kitchen, armory, stairways, hallways, and seven levels. The bar actually has mini liquor bottles, and there also is a music room, formal rooms, a grand ballroom, and a library. It took 13 years to finish this beautiful dollhouse and it weighs somewhere between 815-890 pounds.
