Compared with a standard expandable house, this model features an integrated covered porch / veranda area, creating additional outdoor living space while giving the building a more complete residential appearance.
The house is built around a prefabricated steel structural system and can be customized with insulated wall panels, glass entrance doors, windows, flooring, electrical systems, sanitary facilities and different exterior finishes.
Its compact modular design makes it suitable for international transportation, while factory prefabrication helps reduce on-site construction work and shorten installation time.

The front porch provides a sheltered outdoor area that can be used as an entrance platform, seating area, reception space or outdoor leisure zone.
This design is particularly suitable for residential cabins, resorts, campsites and guest accommodation.
The flat roof gives the building a clean and contemporary architectural style.
It works well with dark steel frames, wood-grain wall panels, white exterior panels and large glass doors.
The main structural system uses a steel frame that supports the roof, wall panels, doors, windows and porch structure.
Factory fabrication helps improve dimensional consistency and simplifies project installation.
The internal space can be configured according to the project application.
Typical options include:
Bedroom
Living room
Bathroom
Kitchen
Office
Reception area
Guest room
Studio
Multi-purpose room
Different exterior appearances can be selected, including:
White metal panels
Gray exterior panels
Dark charcoal finishes
Wood-grain decorative panels
Mixed metal and wood-effect finishes
Glass entrance doors and larger windows can be incorporated to improve natural lighting and create a more open interior.
Different window styles can also be selected according to the destination market.
A large portion of the structure and interior work can be completed in the factory before shipment.
This reduces the amount of traditional construction required at the installation site.
