How to Customize a Prefabricated House

Customizing a prefabricated house requires completion through a professional manufacturer, with the process covering five core stages: requirement communication, design planning, component production, transportation and delivery, and on-site assembly guidance, as detailed below:

1. Requirement Communication: Clarifying Core Parameters
Customers need to provide key information to the manufacturer, including the intended use of the house (e.g., residential, office, elderly care), area, style preferences (modern, rustic, industrial, etc.), and budget range. The manufacturer will conduct a preliminary assessment based on site conditions (e.g., terrain, climate, surrounding environment) to determine a feasible plan. For example, elderly care apartments require barrier-free design, while high-humidity areas need enhanced waterproofing and moisture resistance.

2. Design Planning: Modular Decomposition and Drawing Generation
The design team uses BIM (Building Information Modeling) or specialized modular design software to decompose the house into standard components (e.g., walls, floors, beams and columns) and non-standard components (e.g., irregular roofs, custom doors and windows). The software simulates component connection methods, load distribution, and spatial layout to generate detailed production drawings that include component dimensions, material specifications, and installation sequences. This stage requires repeated confirmation of details with the customer to avoid cost increases from later modifications.

3. Component Production: Precision Manufacturing in a Factory Setting
Production takes place in an enclosed factory, using high-precision molds and automated equipment (e.g., CNC cutting machines, welding robots) to ensure component dimensional errors are controlled within millimeters. Taking light steel structures as an example, the main frame is formed through automated welding, and the walls integrate insulation layers, water and electricity pipelines, and decorative finishes to form a 'sandwich' structure. Some manufacturers offer full-house finishing services, including pre-installation of floors, bathrooms, and cabinets, reducing on-site construction work.

4. Transportation and Delivery: Standardized Logistics Management
Components are designed to fit international standard shipping containers (e.g., 20-foot or 40-foot containers), with packaging optimized to reduce transportation space usage. During transportation, GPS tracking and temperature and humidity monitoring are used to ensure components arrive at the site undamaged. For example, components for prefabricated elderly care apartments purchased from China by the UK are transported via a combination of sea and land freight, with full traceability of the transportation status throughout.

5. On-Site Assembly Guidance: Rapid Assembly and Inspection
A professional team carries out component lifting and connection according to the drawings, using bolt fixation or welding processes to ensure structural stability. The assembly period typically ranges from several weeks to several months, depending on the size of the house. For example, 63 sets of Chinese prefabricated elderly care apartments were fully assembled in just 14 days after landing in the UK. After assembly, airtightness, waterproofing, and structural safety tests are conducted to ensure compliance with local building codes.

Material and System Selection
Mainstream load-bearing systems include light steel structures (lightweight and fast construction), cold-formed thin-walled steel (suitable for low-rise residential buildings), and prefabricated concrete (high durability). The enclosure system needs to integrate thermal insulation materials (e.g., rock wool, polystyrene boards), fire-resistant panels (e.g., gypsum boards), and waterproof membranes to form a complete protective layer. When selecting a manufacturer, key considerations should include its design experience (e.g., similar project cases), production capacity (e.g., automation equipment coverage), and after-sales service (e.g., warranty period, maintenance response speed).
