伊朗采购需求：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 a product size of over 70 meters in a variety of colors. The wider the color range, the better, as I believe that colors bring life and vitality to my projects. I have a unique approach to sustainability, often repurposing materials for my needs. For example, I've designed and built my own solar water heater using sunlight as an energy source, allowing me to enjoy warmth in my home without any cost. I'm eager to discuss options that align with my creative vision!
