In early 2024, Global Brothers International partnered with a renowned Chinese boutique hospitality brand to design and construct a cluster of 12 luxury light steel villas nestled in the hills overlooking Erhai Lake in Dali, Yunnan. The client sought a sustainable, earthquake-resistant, and architecturally expressive solution that respected the region’s cultural landscape and fragile ecosystem.
Challenges
- Environmental sensitivity: Construction near Erhai Lake required minimal site disruption and zero wastewater discharge
- Seismic zone: Dali is in China’s Seismic Zone 8—structures must meet high anti-earthquake standards
- Aesthetic expectations: Villas needed to blend modern comfort with traditional Bai ethnic architectural elements (e.g., sloped roofs, courtyards)
- Short construction window: Local regulations limit heavy construction during rainy season (June–Sept)
Our Solution
Global Brothers delivered a fully customized light steel frame system with integrated insulation, renewable energy readiness, and modular finishes—enabling rapid on-site assembly while meeting both aesthetic and regulatory demands.
✅ Structural & Environmental Features
- Cold-formed light steel frames (Q355 steel), designed per GB 50018 and seismic code GB 50011
- Wall system: 150mm rock wool insulation + vapor barrier + breathable membrane → U-value ≤ 0.35 W/(m²·K)
- Roof: Traditional-style double-pitched roof with hidden solar mounting rails
- Dry construction method: 90% prefabricated off-site, reducing on-site waste by ~70%
- Rainwater collection & greywater recycling system integrated into villa layout
✅ Design & Experience
- Custom façade with local stone cladding and wooden louvers
