6. Fortress
If your children dream of becoming a knight or want to get involved in some Game of Thrones episodes, then Castle Fortress will be a perfect choice for them. One of the towers has three stories. It's a stop whenever your child's friends visit. The design includes turrets, a bridge to talk to the second tower, and a sliding bridge and stone wall.
Designed by Tiny Town Studios, and their Etsy store has this list for $ 37,500. The price may increase or decrease, depending on the features you want to have on the castle fortress. However, if you can afford these playhouses, there's no reason you shouldn't have one for your kids.
