Container House Expansion Plan

The container house expansion plan mainly includes four categories: structural expansion, spatial combination expansion, deformation expansion, and functional integration expansion, which can be flexibly selected according to the usage scenario.

Structural Expansion: Double-Wing or End Expansion Modules

Based on standard containers (20-foot/40-foot), side or end expansion modules are added, increasing the usable area by 30%-50% upon deployment. For example, expandable office containers use hydraulic telescoping structures to extend space, suitable for long-term on-site office use or scenarios requiring high comfort levels. Such designs must ensure that the frame structure complies with the Building Structural Design Code, especially in areas prone to earthquakes or high winds, where wind and earthquake resistance must be enhanced.

Spatial Combination Expansion: Modular Assembly and Stacking

Functional zoning is achieved through horizontal assembly, vertical stacking, or split-level design. For example:

• Assembly Combination: Two to three containers are connected to form a complete flat-level layout integrating a living-dining room, bedroom, and bathroom (approximately 100㎡).
• Split-Level Design: Stacking creates spatial hierarchy, with the ground floor reserved for a courtyard or walkway, improving ventilation and lighting.
• Irregular Combination: A “main container + two side folding modules” structure expands the indoor area to 120㎡, with a built-in electric track system for quick layout adjustments.

Deformation Expansion: Dynamic Space Derivation

Single containers achieve functional derivation through panel folding and hydraulic rod flipping:

• Downward Folding: The container panel forms a terrace, expanding usable space.
• Upward Flipping: Hydraulic rods support the formation of an awning, providing shade.
• Internal Deformation: Paired with movable furniture (such as folding beds and integrated cabinets), space flexibility is enhanced in small units (15㎡).

Functional Integration Expansion: Systematic Upgrade

Equipment such as solar panels, rainwater collection systems, and smart home devices are integrated to achieve a composite function of “building as a system.” For example:

• Energy Self-Sufficiency: Solar panels integrated on the container roof meet 30% of the electricity demand.
• Water Circulation: Rainwater collection systems achieve 100% rainwater recovery.
• Smart Control: Embedded underfloor heating and smart access control devices enhance the living experience.

Core Points of Expansion Design

• Materials and Craftsmanship: Steel and insulation materials that comply with the Building Material Quality Standard are selected. Cutting and welding areas must be polished and coated with epoxy primer + topcoat, with the rust prevention cycle adjusted according to the environment (3-5 years in coastal areas, 8-12 years inland).
• Sealing and Waterproofing: Sealant is used for doors, windows, and assembly seams, replaced every 5-7 years; roof gutters must be regularly cleaned to prevent water accumulation and corrosion.
• Approval and Compliance: Long-term residence requires construction approval and structural drawings; construction is prohibited on cultivated land and basic farmland, and forestry approval is required for forest land.
