Helsinki Key Points and Difficulties in the Design of Container Houses

I. Key Points in Design

Helsinki Space Optimization and Functional Layout

Helsinki

Efficient Zoning: The standard dimensions of containers (such as 20/40 feet) are limited. It is necessary to create multi-layered spaces (such as LOFT design) through cutting, combination, or stacking.

Flexibility: Design detachable partitions, folding furniture, or modular components to adapt to different usage scenarios (residential, office, commercial, etc.).

Helsinki Ergonomics: Reasonably plan the movement routes to avoid a cramped feeling. Pay special attention to the floor height (the height of a standard container is about 2.4-2.9 meters, and the thickness of the thermal insulation layer needs to be reserved).

Helsinki Structural Safety and Stability

Reinforcement Design: Containers were originally designed for transportation. The openings (doors and windows) after cutting need to be reinforced with steel beams to prevent deformation.

Helsinki Seismic Resistance and Load-bearing Capacity: When stacking, it is necessary to calculate the load distribution, and use welding or bolts for fixation. If necessary, add a support frame.

Helsinki Foundation Treatment: Design the foundation (such as a concrete foundation, pile foundation) according to the geological conditions to avoid uneven settlement.

Environmental Adaptability Design

Helsinki

Thermal Insulation: Metal containers are prone to heat conduction. It is necessary to cover the inside and outside with rock wool, polyurethane foam, or vacuum insulation panels, and set up a moisture-proof layer.

Ventilation and Lighting: Large-area windows (such as floor-to-ceiling windows, skylights) combined with sunshade design, and use high windows or ventilators to promote air convection.

Helsinki

Climate Response: Strengthen the airtightness in cold regions, and pay attention to moisture prevention and ventilation in hot and humid regions.

Helsinki

Helsinki Aesthetics and Personalization

Creative Appearance: Break the industrial feel through color painting, external hanging materials (wood veneer, green plant wall), or asymmetric stacking.

Helsinki Indoor Style: Combine the industrial style (exposed structure) or modern minimalist style, and use soft furnishings to balance the cold and hard texture.

Helsinki

Helsinki Sustainability

Helsinki Material Recycling: Give priority to using recycled containers to reduce the carbon emissions of newly built steel.

Helsinki

Helsinki Energy-saving System: Integrate solar panels, rainwater collection devices, and gray water recycling systems to reduce energy consumption.

II. Difficulties in Design

Helsinki Balance of Structural Transformation

Helsinki Cutting the container will weaken its original strength. It is necessary to determine the reinforcement scheme through finite element analysis, such as welding reinforcing ribs or adding support columns, which will lead to an increase in cost and construction period.

Helsinki Anti-rust and Durability

Metal containers are prone to corrosion. After sandblasting to remove rust, it is necessary to coat with an epoxy primer + polyurethane topcoat, and seal the joints. In coastal or high-humidity areas, galvanized steel sheets or weathering steel should be used.

Helsinki Modular Splicing Technology

Helsinki When combining multiple containers, it is necessary to accurately align the interfaces, and use waterproof rubber strips and structural adhesives for sealing to avoid leakage caused by thermal expansion and contraction. The overall stiffness after splicing needs to be enhanced through a frame or truss.

Helsinki Sound Insulation and Comfort

The metal walls transmit sound obviously. It is necessary to fill the interior with sound-absorbing cotton, lay an elastic sound-insulating felt, or adopt a double-layer wall with a hollow design. The floor can be equipped with a floating floor to reduce vibration noise.

Helsinki Pipeline Integration and Concealment

Helsinki The water and electricity pipelines need to be pre-embedded in the interlayer of the wall or floor, and the corrugated structure of the container can be used to hide the wiring, while avoiding drilling holes to damage the structure. Concentrate the equipment area (such as the bathroom module) to simplify the pipelines.

Helsinki

Helsinki Regulatory and Approval Barriers

Helsinki

In some regions, container houses are classified as temporary buildings and need to comply with codes such as fire protection (escape routes, flame-retardant materials) and seismic resistance. Communicate with the planning department in advance about the nature of the land use and permits.

Helsinki

Transportation and Construction Constraints

Helsinki

Large combined structures need to be disassembled for transportation. On-site hoisting depends on heavy equipment, and the site needs to meet the requirements for passage and hoisting space. The cost is relatively high in remote areas.

Helsinki

Thermal Bridge Effect Control

Helsinki The metal skeleton is prone to forming a thermal bridge. It is necessary to set up a thermal bridge-breaking structure between the internal and external thermal insulation layers, such as using thermal insulation gaskets or non-metallic connectors.

Helsinki III. Examples of Innovative Solutions

Prefabrication Design: Complete 80% of the decoration and pre-embedding of pipelines in the factory to reduce the difficulty of on-site construction.

Hybrid Structure: Combine containers with light steel structures to expand the space span (such as a cantilevered terrace).

Helsinki Smart System: Integrate smart home systems (temperature control, lighting) to improve comfort and make up for the limitations of the physical space.

Helsinki Vertical Greening: Plant climbing plants on the facade to naturally regulate the microclimate and enhance the aesthetics.

Helsinki

Conclusion

Helsinki

Helsinki

The core of the design of container houses lies in balancing the efficiency of modularization and the humanized experience, and it is necessary to achieve the unity of function, safety, and aesthetics within a limited space. Designers need to have interdisciplinary knowledge (structural engineering, building physics, etc.) and fully combine the local environment and user needs in order to overcome the difficulties and create a sustainable and innovative space.
