坦桑尼亚采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm looking for expandable two-bedroom accommodations suitable for a destination in Nairobi, Kenya. The focus is on flexibility and comfort, as the space may need to cater to varying group sizes or purposes. I'd appreciate details on the available options, including dimensions, features, and customization possibilities. Additionally, please provide any information about amenities, pricing structures, and lead times for availability. I'm particularly interested in understanding how the design can adapt to different needs while maintaining a welcoming environment. Recommendations on suppliers or manufacturers who specialize in this type of product would also be very helpful. Looking forward to your response!
