Second-Hand Container House Design
Designing a house from a second-hand container requires comprehensive consideration of four aspects: size planning, physical comfort, water and electricity connections, and design style, to ensure both functionality and aesthetics.
1. Size Planning: Pre-design for Module Assembly
Second-hand containers come in various sizes, with common types including 20-foot small containers (6 meters long/2.35 meters wide/2.4 meters high/33.2 cubic meters volume), 40-foot flat containers (12 meters long/2.35 meters wide/2.4 meters high/67.7 cubic meters volume), and 40-foot high containers (12 meters long/2.35 meters wide/2.7 meters high/76.3 cubic meters volume). When designing, determine the module assembly method based on the intended layout, such as using a single container independently or combining multiple containers in a staggered manner. The key step is to first draw a design plan, specifying window locations, door openings, and staggered structures, and then select the appropriate container model based on the drawings to avoid space wastage or structural conflicts caused by 'buying the container first and designing later'. For example, if creating a two-story space, reserve a location for stair installation and calculate whether the floor height meets requirements.
2. Physical Comfort: Sound Insulation and Thermal Insulation Are Essential
Containers are essentially industrial metal structures with poor sound insulation and thermal insulation properties. Sound insulation cotton and thermal insulation layers must be added; otherwise, noise may be generated due to metal resonance during the rainy season, and the interior may become cold in winter due to rapid heat conduction. Sound insulation cotton can be filled in the wall cavities, and thermal insulation layers are recommended to use polyurethane foam or rock wool boards, with thickness adjusted according to local climate (e.g., not less than 5 centimeters in cold regions). Additionally, the floor should be covered with a moisture-proof membrane and wooden flooring or tiles to prevent slipperiness caused by condensation.
3. Water and Electricity Connections: Scientific Planning of Pipeline Routes
Containers, originally designed as transportation tools, lack pre-installed water and electricity systems and require independent design. Water supply and drainage pipes should be concealed along walls or floors to avoid exposure affecting aesthetics; when assembling multiple modules, plan pipeline connection routes in advance to ensure stable water pressure and smooth drainage. For example, drainage pipes from bathrooms and kitchens can be concentrated at the main sewage outlet, reducing bends to lower the risk of blockage. For electrical circuits, reserve sufficient sockets and use waterproof designs; leak protection devices are recommended for damp areas such as kitchens and bathrooms.
4. Design Style: Balancing Personalization and Practicality
Design styles can be flexibly adjusted according to personal preferences. Minimalist style can be achieved by combining white paint with wooden furniture to create a bright space; industrial style can retain the original container color, paired with metal lighting fixtures and exposed pipes; natural style can incorporate green plants and raw wood elements. For example, one case used a projection screen, open kitchen, and fully functional bathroom to create a cozy internet-famous cottage; another case achieved a three-bedroom, one-living-room layout through multi-container assembly, using top-tier decoration materials to balance luxury and practicality.
