Through modular splicing technology, 

Components are precision processed in the factory and then transported to the site to achieve ‘building block’ construction, 

Significantly reducing labour costs and time consumption. 

▲ The features of expandable house are as follows:

1. Easy to move, easy to reassemble

Housing modules can be freely combined, disassembled and expanded according to demand, supporting personalised customisation. 

For example, the modular house can be stacked (up to 7 floors), and the layout and functions can be adjusted to adapt to the diversified scenarios such as temporary housing and mobile office. 

The design style covers modern simplicity, European classical, Chinese traditional, etc., to meet different aesthetic needs.

2. Superior quality for safe living

Light or heavy steel structures are used, with high strength, earthquake and wind resistance. 

For example, beams and columns absorb seismic energy through flexible connections, and the surface materials are corrosion- and moisture-resistant, with a service life of more than 20 years. 

The factory strictly tests the quality of the components to ensure overall stability and safety.

3. Environmentally friendly materials

The production process reduces construction waste and materials can be recycled. 

The integrated houses mostly adopt green technologies such as solar panels and rainwater collection systems to reduce energy consumption; 

The light steel structure has the function of ‘breathing’, which regulates the humidity of indoor air and improves comfort.

4. Efficient production, shorten construction period

Factory prefabrication reduces the overall cost and makes the price more competitive. 

The overall light weight of the house supports quick dismantling and off-site reconstruction, which is especially suitable for temporary sites and frequent relocation.

5. Functional integration and space optimisation

The structural design of the building is highly integrated with its functions, such as roof ventilation systems and light belts to optimise air circulation and heat dissipation. 

The internal space can be flexibly adjusted according to the usage requirements to maximise practicality.

Maybe You Ask

1.What is a modular house? 

The core of modular house is to split the building into multiple functional modules (e.g. walls, floors, roofs, etc.), 

and complete the standardised production in the factory, including the structure, pre-burial of pipelines and internal decoration processes, to realise the ‘industrialised manufacturing’ mode. 

For example, the container modular house is processed into a uniform specification box through the assembly line, 

and then transported to the site to be assembled for residential, commercial and special scenarios.

2.Application Scenarios of Modular Integrated Housing:

• Rural construction, improve living conditions

• Temporary buildings, e.g. construction site dormitories

• Tourist attractions, providing accommodation services

• Temporary accommodation after natural disasters

3.Five elements to consider when customising a modular integrated house

I.clear demand and use of the scene

• Occasions for use

Temporary site dormitory or emergency shelter: it is recommended to choose easy-to-dismantle movable boarding house or container house with low cost and flexible installation.

Commercial use (e.g. temporary shop, cafe): recommend customised container house, which can be combined with high-end decorations such as aluminium panels to enhance the tone.

Long-term residence or holiday villa: light steel/wooden structure houses are preferred for better insulation and comfort.

• Budget control

Short-term use: movable panel house or basic container house is cost-effective, with low unit price and low maintenance cost.

Long-term investment: light steel or wood structure has higher initial investment but better durability and lower long-term maintenance cost.

• Site legality

It is necessary to confirm the nature of the land in advance and apply for temporary building approval.

The approval process can be simplified if the land is owned and does not disturb the public.

II. Material and structural performance

• Type of structure

Light steel structure: strong seismic and wind resistance, suitable for earthquake-prone areas, service life up to 20 years or more.

Container modules: the welding process and corrosion resistance of the surface materials (e.g. corrugated sheets, aluminium sheets, etc.) need to be checked.

• Fireproof and waterproof performance

Fire prevention: choose sandwich panels filled with fire-retardant materials such as rock wool, and avoid the use of flammable materials such as foaming agents.

Waterproofing: Check the sealing of roof panels and supporting members to avoid light and wind leakage.

• Material durability

The thickness of surface tin is recommended to be ≥0.5mm, and the interlayer material should meet the requirement of thermal insulation.

Prefer factory prefabricated standardised components for more stable quality.

III.Functionality and design adaptability

• Space layout and functional integration

Design doors and windows according to the needs of personnel flow to ensure convenient access.

Integration of roof ventilation, lighting strips and other systems to optimise air circulation and heat dissipation.

• Aesthetics and customisation

Optional decorative materials such as wood veneer and aluminium panels are available for the façade to enhance the visual effect.

Support free combination of modules to meet personalised functional zoning (e.g. office area, living area).

• Expandability

Reserve module splicing interface for future layer increase or layout adjustment.

IV.Construction and supplier selection

• Schedule and Construction Efficiency

Projects with a high prefabrication rate can shorten the construction period to 1/3 of traditional construction, especially for urgent needs.

• Supplier Qualification

Prefer brands with professional factories and quality management systems to ensure component accuracy.

Case references and after-sales service commitments are required.

V. Maintenance and Environmental Protection

• Maintenance cost

Regularly check the sealing of dovetail groove structure and connectors to prevent cracking or falling off.

• Environmental Protection and Recycling

Select recyclable materials (e.g. steel) to reduce construction waste.

Integrate green technologies such as solar panels and rainwater collection systems to reduce energy consumption

4.How much does a modular home cost price？

The cost of modular housing is affected by a number of factors such as materials, functionality, design complexity, etc. 

It is recommended to choose an option based on the usage scenario and budget range. 

For example:（Fees are in RMB for a combination of reasons, if you need the exchange rate you can click here.）

100m² temporary house: total budget about 70,000-80,000 RMB (basic container module);

200m² long-term housing: total budget of about 170,000-200,000 yuan (light steel + energy-saving integrated programme).

I. Base cost range

• Comprehensive cost of modular house

Conventional modular housing: cost per square metre is RMB 750-850 (including materials, labour, structural pre-embedding, etc.), 

which is slightly higher compared to traditional brick-concrete structures (RMB 600-700/m2 ), 

but the construction cycle is shortened by 30% to 50% High-end customised solutions: integrated solar energy.

High-end customised solutions: after integrating solar energy, smart home and other systems, the cost may rise to RMB 2,000-5,000/㎡.

• Breakdown of cost composition

Material costs: Hairong energy-saving modules, light steel structure and other main materials account for about 60%-70% (450-600 RMB/㎡), including steel, concrete, insulation, etc.

Labour and construction: on-site assembly cost is about 220-260 RMB/㎡, and the transport cost in remote areas is increased by an additional 5%-10%.

II. Core factors affecting the budget

• Material and structure type

Light Steel Structure: Initial investment is higher (about RMB 850/㎡), but low maintenance cost, strong anti-seismic performance, suitable for long-term residence.

Container module: the cost of the basic model is about 700 RMB/㎡, suitable for temporary scenarios; aluminium panel exterior or stacked design can be upgraded to 1,200 RMB/㎡.

• Function integration and design complexity

Adding functional modules such as roof ventilation and lighting belt increases the cost by 10%-15%.

Complex layout (e.g. L-shaped splicing, multi-layer stacking) needs to reserve splicing interface, increasing the design cost by about 5%-8%.

• Environmental protection and energy-saving technologies

Integration of solar panels, rainwater recycling system and other green technologies, the initial cost increase of 20% -30%, but long-term energy costs can be reduced by more than 40%.

III. Long-term Cost and Maintenance

• Maintenance Costs

The annual maintenance cost of the modular house is about 1%-2% of the construction cost 

(e.g., the average annual maintenance cost of 100m2 house is about 1500 RMB), which is lower than that of traditional buildings.

Focus on the maintenance of connectors sealing, surface anticorrosion coating, etc., to avoid cracking or rusting.

• Energy-saving benefits

The thermal conductivity of materials such as sea capacitance module is only 0.028W/m-K, 

and the characteristics of warmth in winter and coolness in summer can save air-conditioning energy consumption by more than 50%.

IV. Budget Control Recommendations

• Selection of module type according to need

Temporary use (site dormitory, shop): basic container module (700-800RMB/㎡) or movable panel house (500-600RMB/㎡).

Long-term residence: light steel + thermal insulation integrated solution (RMB 850-1000/㎡), with priority given to durability.

• Optimise design and supplier management

Adopt standardised modules to reduce the need for customisation and design costs.

Select factory direct suppliers to avoid intermediary mark-ups (e.g. Haiyong module direct cost reduction of 10%-15%)
