意大利采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm currently in the market for an abitative solution with a space of around 35 to 40 square meters. My budget is set at 8000 euros. I'm seeking options that provide not only comfort but also efficiency and aesthetic appeal. It's crucial that the design maximizes the available space while incorporating practical features for daily living. Additionally, I'm interested in any sustainable or innovative materials that can be used in the development of this solution. Please include any customization options available and estimated timelines for delivery. Looking forward to your suggestions and ideas on how we can work together to find the best option within my budget.
