Constructing a MUJI prefabricated home involves precise coordination but offers efficiency. Follow these steps:
1. Pre-Construction Essentials
Site Preparation: Ensure your land is accessible, level, and utilities (water, electricity, sewer/septic) are available at the connection points. Clear vegetation and establish a stable base.
Permits & Approvals: Secure all necessary building permits and ensure MUJI's prefab design complies fully with local zoning regulations, building codes, and any homeowners' association (HOA) requirements.
Foundation: Install the required foundation type (commonly concrete slab or crawl space) as specified by MUJI and engineered for your site conditions. Accuracy is critical for module placement.
2. MUJI Prefab Delivery & Assembly
Delivery: Modules arrive factory-finished (walls, windows, floors, MEP rough-ins). Ensure clear access roads and adequate crane placement space.
Crane Placement: Using a heavy-duty crane, modules are carefully lifted from delivery trucks and precisely set onto the foundation anchors according to the engineered plan.
Joining Modules: Professional installers bolt modules together using MUJI's specified connection system, creating a structurally unified unit.
Roofing Integration: Install MUJI's prefabricated roof panels or assemble the roofing system over the joined modules.
Exterior Sealing & Flashing: Seal all joints and connections between modules and around the roof meticulously to prevent water ingress and ensure air tightness.
3. Post-Assembly Completion
Utility Connections: Licensed professionals connect the prefab's internal MEP systems to the main external utility lines.
Interior Finishing: Complete tasks like installing:
- Drywall finishing
- Flooring
- Built-in cabinetry (hallmarks of MUJI design)
- Final plumbing fixtures
- Lighting fixtures and electrical outlets/switch plates
Final Inspections: Schedule and pass all required final building inspections.
Key Considerations: MUJI prefabs emphasize high-quality materials and clean aesthetics. Understand the customization limitations within the prefab system early. Strictly adhere to MUJI's assembly guidelines and rely on their trained installers for core assembly.
