Container House Renovation Flowchart

The renovation process for container houses can be divided into five stages: preliminary planning, structural renovation, basic decoration, soft decoration optimization, and post-maintenance. The specific steps are as follows:

1. Preliminary Planning and Site Preparation

• Purpose and Site Confirmation: Clarify the intended function after renovation (e.g., residential, studio) and select a compliant site. Verify land properties (e.g., rural homesteads require approval), fire safety, and urban management restrictions to avoid illegal construction.
• Container Selection: Choose the size based on needs (20-foot or 40-foot recommended). Inspect used containers for rust and deformation; new containers are more expensive but offer stable quality.
• Pipeline Embedding: Plan the layout of water and electricity pipelines, coordinate temporary pipeline connections, and ensure convenience for subsequent construction.

2. Structural Renovation and Reinforcement

• Load-Bearing Structure Protection: Avoid altering the load-bearing frame of the container randomly. Confirm stress points before cutting doors and windows to prevent structural instability.
• Opening and Reinforcement: Use a cutting machine to precisely open windows and doorways, and seal edges with waterproof glue. For multiple container connections, use angle steel welding for reinforcement. For two-story structures, add load-bearing supports to ensure safety.
• Roof Renovation: Replace corrugated steel sheets with transparent skylights (requires professional welding) and ensure proper waterproofing to prevent leakage.

3. Basic Decoration

• Waterproofing: Focus on treating areas around doors and windows, joints, and roof gutters. Replace sealant every 5-7 years to prevent rust.
• Insulation and Lighting: Install internal insulation layers on walls and roofs, and choose triple-glazed windows to enhance thermal insulation. Increase natural lighting through large floor-to-ceiling windows, skylights, or glass partitions.
• Facade Beautification: Apply paint, themed murals, or glass curtain walls to cover the container surface, reducing the industrial feel and enhancing aesthetics.

4. Soft Decoration and Functional Optimization

• Space Utilization: Use foldable beds, tables, and integrated cabinets to enhance space flexibility. Design customizable foldable beds for bedrooms that can transform into sofas when partially folded.
• Detail Design: Use rounded edges in bathrooms and integrate storage cabinets. Add wooden veneers to the inner side of container doors for a unified interior color scheme. Reserve sockets and network interfaces on walls to meet modern needs.

5. Post-Maintenance

• Rust Prevention: Grind and apply epoxy primer and topcoat to cut and welded areas. Inspect welds, corners, and other rust-prone parts annually and touch up paint as needed.
• Moisture Control: Elevate the container bottom on pile foundations to avoid direct ground contact and prevent moisture intrusion. Use dehumidifiers indoors to maintain a dry environment.

Note: For long-term residence, obtain building approval according to local requirements and provide structural drawings to ensure compliance.
