Case Study: 76㎡ Two-Story Modular Home in Spain

1. Project Background & Client Needs

• Location: Girona, Catalonia, Spain (a scenic area near the Mediterranean coast).
• Client Requirements:
  1. A 76㎡ two-story modular home with 3 bedrooms, 2 bathrooms, and a rooftop terrace.
  2. Modern luxury design that blends with the Mediterranean landscape.
  3. Full compliance with EU construction codes (CE certification, fire safety, energy efficiency).
  4. Construction completion within 3 months to meet the family’s move-in timeline.

2. Core Design & Customization

2.1 Architectural Design

• Layout: 76㎡ total area (38㎡ per floor). Ground floor: Open-plan living/dining room + kitchen + guest bathroom. Upper floor: Master bedroom + 2 guest bedrooms + master bathroom + rooftop terrace.
• Exterior Aesthetics: White aluminum composite panel cladding + large floor-to-ceiling windows + wooden accents (reflecting local Catalan architecture).
• Rooftop Terrace: 15㎡ outdoor space with glass railings, designed for barbecues and sea views.

2.2 Material Selection (High Performance)

• Structure: Galvanized steel frame with anti-rust treatment (15-year warranty).
• Exterior: 3mm aluminum composite panels (ACP) – lightweight, weather-resistant, and low-maintenance.
• Insulation: 80mm PU insulation + double-glazed Low-E windows, achieving a building energy efficiency rating of Class A (Spanish CTE standard).

3. Compliance with EU & Spanish Regulations

• CE Certification: All modular components passed EU CE testing for safety and environmental performance.
• Fire Safety: Non-combustible exterior materials and fire-resistant wall partitions met Spain’s technical building code (CTE).
• Energy Efficiency: High insulation ratings reduced the home’s energy consumption by 60% vs. traditional brick-and-mortar homes, qualifying for Spanish green energy subsidies.

4. Construction Process & Timeline

• Factory Production (Weeks 1-4): The 76㎡ modular unit was fully fabricated in Hongyuan Yunshe’s factory, including pre-installed electrical wiring, plumbing, and insulation.
• Transportation (Week 5): The modular home was shipped in 4 standard containers to Girona, reducing transportation costs vs. bulk materials.
• On-Site Installation (Weeks 6-8): 2-3 local workers assembled the modular home on a concrete foundation in 7 days.
• Total Timeline: The project was completed in 7.5 weeks, 0.5 weeks ahead of schedule.

5. Project Outcomes & Client Feedback

• Cost Savings: Total costs were 25% lower than traditional brick-and-mortar construction of the same size and quality.
• Energy Savings: The home operates at near-zero energy costs due to high insulation, saving the client €1,500-€2,000 annually on utilities.
• Guest Experience: The client reported a 4.9/5 satisfaction rate, highlighting the space’s functionality, natural light, and eco-friendly features.
• Resale Value: Modular homes in Spain now command a 15-20% higher resale value due to their sustainability and modern design.

6. Key Takeaways for European Modular Projects

1. Regulatory Expertise: Partnering with manufacturers experienced in EU/CE standards is critical to avoid delays.
2. Climate Adaptation: 80mm insulation is critical for Southern Europe to handle hot summers and mild winters.
3. Aesthetic Alignment: Incorporating local architectural elements (e.g., wooden accents, white washed exteriors) enhances acceptance.
