秘鲁采购需求：蝴蝶预制房屋，双翼扩展集装箱房屋，可扩展集装箱房屋，弹出式模块化房屋，预制房屋

I'm looking for information on expandable container houses. Specifically, I'm interested in understanding the various options available, including different design layouts and customization features. It would be great to know about the materials used, the dimensions, and any energy efficiency certifications these houses might have. If you have brochures or catalogs, please share those as well. Additionally, could you provide details on pricing, minimum order quantities, and lead times for delivery? I'm keen to explore both standard models and any innovative solutions you might offer. If possible, I'd appreciate any references or case studies showcasing previous projects. This will help in evaluating the potential fit for our needs. Thanks!
