Complete Guide to Container House Renovation

Currently, there is no publicly available universal plan for the complete renovation of container houses, but key renovation steps and points can be summarized through practical cases.

I. Basic Framework Construction
Taking the case of a couple renovating two containers into a three-bedroom, one-living-room home as an example, the initial stage of renovation requires prioritizing the construction of the structural framework. First, assemble the framework for the corridor roof using wooden beams as the primary material, enhancing efficiency through standardized modular assembly to ensure roof load-bearing capacity and stability. Subsequently, construct the wall framework by determining wall positions and dimensions according to design drawings, using angle iron or square tubing for welding or bolt fixation to form an overall support structure. After framework completion, level calibration is necessary to avoid deviations in subsequent construction.

II. Wall and Roof Treatment
After installing the wall framework, wall materials need to be laid. In this case, waterproof boards are chosen as the main material for the corridor walls, meeting moisture-proof requirements while facilitating subsequent decorative layer construction. Roof treatment requires consideration of drainage and lighting: if skylights are to be installed, the roof outer frame needs to be remade to reserve opening positions and strengthen the structural integrity around the openings; if a traditional pitched roof design is adopted, waterproof membranes need to be laid and drainage gutters installed. In the case of renovating a 6-meter container into a cozy cottage, the roof may adopt a composite structure of insulation cotton and color-coated steel plates to enhance thermal insulation performance.

III. Functional Zoning and Space Optimization
Renovating dual containers requires dividing functional areas through internal partitions. In the three-bedroom, one-living-room case, space connectivity is achieved by removing part of the container side panels, and light steel keel partitions are used to divide the bedrooms, living room, and kitchen. It is important to reserve positions for doors and windows and ensure firm connections between partitions and the framework. For small-unit renovations, the 6-meter container case can be used as a reference, adopting foldable furniture and built-in storage designs, such as lift-top dining tables and wall-mounted beds, to maximize the use of limited space.

IV. Plumbing and Electrical Systems and Hidden Works
Plumbing and electrical renovations are core aspects of container house construction. It is necessary to plan pipeline routes in advance and embed PVC or metal pipes in walls and floors to avoid structural damage from later trenching. The electrical system requires installation of leakage protection devices and sufficient socket positions; the plumbing system needs frost protection measures, with electric heating tapes recommended for northern regions. All pipeline connections need to be sealed to prevent leakage.
