What Is a K Type Prefab House?

A K type prefab house is an environmentally friendly, economical modular building system that takes 1K (1820mm) as its standard dimensional module. Also known as a slope-top prefabricated house, the K type prefab house uses a light steel skeleton system combined with rock wool or EPS sandwich panels for walls and roof, delivering superior insulation, fire resistance, and weather protection.
Unlike conventional construction, every component of the K type prefab house is factory-manufactured and arrives on site ready for fast bolt assembly — no welding required. A team of 6 workers can assemble 20-30㎡ per person per day, making it one of the fastest temporary building solutions available today.
Available in single, double, and three-story configurations, E-TOM K type prefab houses can be freely combined horizontally and vertically to create offices, dormitories, dining halls, clinics, classrooms, and large-scale construction camps. According to the International Organization for Standardization (ISO), modular building systems like the K type prefab house represent a growing global standard for sustainable and efficient construction.

K Type Prefab House Configurations

Type 1 – Single Storey   K Type Prefab House

The single storey K type prefab house is the most economical and widely used configuration. Ideal for construction site offices, worker accommodation, restaurants, activity rooms, and cultural spaces, it offers fast construction and can be fully disassembled and relocated when the project is complete. A cost-effective first choice for projects with limited budgets.

Type 2 – Double Storey K Type Prefab House

The double storey K type prefab house provides double the usable floor space on the same ground footprint — ideal for construction sites with limited land area. This configuration is widely used as a multifunctional complex combining office and accommodation spaces, maximizing efficiency without increasing the site footprint.

Type 3 – Three Storey K Type Prefab House

The three storey K type prefab house is engineered to maximize land utilization and accommodation capacity. Designed for labor-intensive projects, this configuration provides a centralized and efficient solution for large workforce camps, integrating dormitories, offices, dining, and recreational facilities in one compact complex.
