I. Standard Specifications

1. 3 meters × 6 meters × 2.8 meters
   This is the most common container house specification in the Chongqing area, with an internal net height of about 2.6 meters and an area of 18 square meters. Its design is suitable for scenarios such as construction site offices and temporary residences. Inside, it can accommodate a double bed, a simple desk, and a standing wardrobe, offering high space utilization without feeling cramped. This specification uses double-layer color steel plates with rock wool insulation in the walls, providing thermal insulation performance. It keeps out heat in summer and prevents frost in winter. Additionally, there are reserved maintenance openings and exhaust vents on the top, and exhaust fans can be installed to improve ventilation.

2. 3 meters × 3 meters × 2.8 meters
   A small-sized specification with an area of 9 square meters, usually customized according to special customer requirements. Due to its small size, material utilization needs to be optimized. It is suitable for scenarios with extremely low space requirements, such as temporary tool rooms or small guard posts.

3. 7 meters × 3 meters × 2.8 meters
   An expanded specification with an area of 21 square meters, often used for two-story container mobile homes. It is equipped with corridors and balconies to meet the demand for larger spaces.

II. Customized Specifications

The sizes of customized container houses are flexible and diverse, such as 3 meters × 8 meters and 3 meters × 9 meters. The length or width can be adjusted according to project requirements. In some cases, the houses are composed of multiple containers. For example, the office building in an industrial park in Chongqing is formed by splicing 8 containers into a two-story structure, and the management building in a scenic spot is built with 4 containers into a two-story commercial office space.
