Sunfine: Professional Modular and Container Building Solutions
Founded in 2011 (with roots dating back to 2006), Xiamen Sunfine is a factory-direct manufacturer of modular and container-based buildings. We specialize in high-precision expandable container homes, flat-pack modular units, and fast-install panel houses for global markets.
With over 16 years of industry expertise and 13 years of dedicated export experience, we support wholesalers, developers, contractors, hospitality operators, and private buyers with reliable modular solutions for residential, commercial, and temporary use. Our in-house production model ensures consistent quality control, flexible customization, and stable delivery timelines.
Our Core Modular Building Systems
1. Expandable Container Homes (16-76 m2)
Our flagship space-efficient solution for ADUs, granny flats, and residential use. These units are folded to standard container size for cost-effective transport and then expanded on-site to deliver a spacious, fully functional interior. Available in 20FT, 30FT, and 40FT configurations.
2. Flat-Pack Modular Units (20FT / 40FT)
Designed to maximize container loading efficiency, these units can be assembled on-site in a matter of hours. Ideal for dormitories, classrooms, staff housing, and cafeterias. Units can be seamlessly combined to create larger open-plan community spaces.
3. Fast-Install Panel Houses (EPS / PU / PIR)
Energy-efficient modular houses designed for rapid assembly and long-term durability. Featuring excellent thermal performance and seismic resistance, they are widely used for guesthouses, farm stays, and eco-tourism projects.
4. Foldable Container Structures
Engineered for extreme mobility and rapid deployment. These are commonly used as temporary offices, emergency shelters, and clinics. They are easy to transport, relocate, store, and reuse multiple times.
5. Portable and Mobile Toilets
Durable and hygienic units designed for construction sites, events, and campgrounds, with a proven track record of supply across Latin America and Oceania.
