南非采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm looking to purchase a 6m x 6m container house equipped with essential electrical and plumbing systems. The unit should include a functional bathroom featuring a shower, a kitchen area with a sink, and a toilet basin. It's important that the design is efficient and well-organized to maximize space, as I'll be using it in Durban, South Africa. Could you provide me with more details about the available options, including insulation and material quality? I'd also appreciate information on pricing, lead times for delivery, and any customization possibilities. If there are different models or designs that fit this description, please let me know. Your prompt response will help me move forward with my plans!
