Dongfeng Container House Renovation

The renovation of container houses in Dongfeng Town can achieve functional and comfort upgrades through a systematic process. The core steps and techniques are as follows:

I. Basic Renovation Process

1. Planning and Design
   Determine the purpose of the house (residential/office), spatial layout, and future expansion needs. The design should cover the positions of doors and windows, thermal insulation and heat preservation solutions, ventilation and lighting paths, etc., ensuring compliance with building safety regulations. For example, residential spaces need to reserve areas for bathrooms and kitchens and plan the embedding paths for water and electricity pipelines.

2. Container Selection and Preparation
   Prioritize containers without severe rust, deformation, or structural damage, focusing on inspecting load-bearing parts such as corner posts and floor panels. After selection, thoroughly clean the container body, remove oil stains, old paint, and mold, use an angle grinder to polish rusted areas to a metallic luster, and apply a high-efficiency rust remover.

3. Structural Renovation
   Cut door and window openings according to the design drawings. If necessary, weld multiple containers to expand the space (such as horizontal side-by-side or vertical stacking). All structural modifications need to be calculated and verified for safety, and steel beams or columns should be added for reinforcement at load-bearing weak points. For example, a reinforced frame should be welded at the connection points of stacked containers to ensure overall stability.

4. Thermal Insulation and Rust Prevention Treatment

• Rust Prevention: Spray anti-corrosion coatings such as epoxy zinc-rich paint on the inner and outer surfaces of the container to enhance weather resistance.
• Thermal Insulation: Fix wooden or light steel studs on the inner walls of the container, fill them with materials such as rock wool or polyurethane foam boards, and cover the outer layer with metal carved panels or anti-corrosion wood decorations. For low-cost solutions, recycled cotton, mineral wool boards, and other scrap materials can be used, and foam insulation layers can be sprayed on the roof.

5. Interior Decoration and System Integration
   Lay floors (such as second-hand wooden floors or PVC floor coverings), install wall panels and ceilings, arrange water and electricity pipelines, and install bathroom and kitchen facilities. Integrate electrical systems (prioritize the use of LED energy-saving lights and solar power supply), water supply and drainage systems, and ventilation systems (such as adding skylights or PVC ventilation ducts on the roof) to ensure the house is suitable for living.

II. Renovation Technique Optimization

1. Key Points for Renovating Old Containers

• Structural Inspection: Before renovation, professionally inspect the container body for rust and deformation to avoid using containers with structural damage.
• Low-Cost Solutions: Use recycled materials (such as old doors and windows, second-hand photovoltaic panels) to reduce costs. Hang canvas or plant climbing vines for sunshade and cooling.

2. Functional Upgrade Directions

• Space Expansion: Increase the usable area by side-by-side or stacking containers. Install a foldable terrace on the roof (with a load-bearing capacity of ≥300 kg/㎡) to enhance functionality.
• Lighting Optimization: Change the south facade to floor-to-ceiling windows (accounting for 60% of the wall), add skylights on the roof (1 square meter for every 20 square meters), and use Low-E glass for energy saving.
• Ecological Design: Set up planting troughs on the west-facing wall, pair them with climbing vines to form ecological sunshades; reserve expansion interfaces on the side walls for future upgrades.

3. Comfort Improvement

• Ventilation Optimization: Utilize the principle of hot air rising for natural ventilation through skylights or PVC ducts on the roof, and use screens to prevent mosquitoes.
• Storage Design: Use the floor height to set up lofts or hanging cabinets, and use multi-functional furniture such as folding tables and sofa beds to save space.
