Cave house is very elegant. The inside of the house is very luxurious. Racangan made so amazing, I was informed that the house was sold on ebay. The house is located in Missouri, USA nd is on sale on Ebay for $ 300,000. The house is very big. You can see pictures of this design. Look at the composition of this house. It looks very neat and large, there is a very unique home furnishings. Some furniture is made of wood, I think this house is very warm and comfortable.
