Container Old House Renovation Design

The renovation design of container old houses requires comprehensive consideration of functionality, cost, structural safety, and compliance. Here are the key design points:

1. Clarify Renovation Goals and Budget

• Functional Positioning: Determine the purpose based on needs (such as residential, studio, homestay, etc.). Different functions have varying requirements for spatial layout, lighting, and ventilation. For example, a residential house needs to divide into bedrooms, a kitchen, and a bathroom, while a studio can simplify the zoning.
• Budget Control: Renovation costs are influenced by the number of containers, materials, and craftsmanship. For example, the basic renovation of a single standard container (3m×6m) costs approximately 13,000 to 110,000 yuan. If additional insulation layers, custom doors and windows, and interior decoration are added, the cost may be higher.

2. Structural Safety and Reinforcement

• Load-Bearing Inspection: Old containers may have rust or deformation, requiring professional inspection of roof load-bearing capacity, ground settlement, and column stability. For example, before 2005, the ground load capacity of warehouses was generally 3 tons/㎡. If heavy-duty shelves need to be placed, reinforcement to at least 5 tons/㎡ is required, costing about 80-150 yuan/㎡.
• Rust Prevention Treatment: The exterior walls of the container need to be sprayed with anti-rust paint, and the interior needs to be waterproofed to extend its service life.

3. Spatial Layout and Functional Optimization

• Modular Combination: Expand space by splicing or staggered stacking containers. For example, connecting two containers can create a flat-floor layout with an integrated living and dining area, two bedrooms, and a bathroom (about 100㎡). Staggered stacking can create a terrace or courtyard, improving ventilation and lighting.
• Multi-functional Furniture: For small units, it is recommended to use folding beds, folding tables, and integrated cabinets to enhance space flexibility. For example, a 15㎡ container can use a custom folding bed that serves as a sofa during the day and unfolds into a double bed at night.

4. Insulation and Lighting Design

• Insulation Layer: Install interior insulation layers (such as polystyrene boards, rock wool boards) on walls and roofs, and choose triple-glazed windows to improve thermal insulation performance, ensuring warmth in winter and coolness in summer.
• Natural Lighting: Install large floor-to-ceiling windows, roof skylights, or glass partitions to reduce reliance on artificial lighting. For example, a container cottage in the forest introduces natural light through a full glass wall design, creating a sense of transparency.

5. Compliance and Approval

• Procedure Handling: Before renovation, confirm the land nature (such as non-construction land needing to meet conditions like recyclability and high area utilization rate) and handle fire protection and planning approvals. For example, converting from warehousing to logistics requires re-determining the fire hazard category. Fire protection renovation accounts for 25%-35% of the total budget and must be applied for on behalf of others; otherwise, it cannot pass the acceptance inspection.
• Subsidy Application: Some regions provide special financial support for old house renovations. For example, Qingbaijiang District in Chengdu offers subsidies of up to 15%-20% of the renovation costs for logistics function upgrade projects.
