澳大利亚采购需求：苹果小屋，集装箱房屋，可扩展房屋，单体钢别墅，太空舱

I'm interested in acquiring a 40-foot expandable house and would like to get more details on the specifications and price range. Could you provide insights into the features, dimensions, and materials used in the construction? Additionally, please include the estimated shipping costs and delivery times to Brisbane Port, Australia. If you have any brochures or product images, that would be helpful as well. Looking forward to your prompt response!
