美国采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm looking for a unit that features 1 bedroom and 1 bathroom, with a total approximate area of 500 to 600 square feet. Ideally, the layout should have an open living space that seamlessly connects to the kitchen. This design is important for maximizing functionality and creating a comfortable living environment. Please provide details on the available options that meet these specifications. It would be great to know the different styles, amenities, and any customization options you offer. Additionally, I'd appreciate information on the estimated lead time for production and delivery. Looking forward to your prompt response!
