Building Module


Utilizing steel shipping containers, modular buildings are composed of a roof panel, floor board, corner posts, and wall panels. The lightweight yet strong components of the shipping containers facilitate modular design and manufacturing that are perfect for low cost structures that can be assembled in seemingly no time.

Flat pack containers meet the structural standards of a wide range of international governing bodies. All other components of the buildings are installed at the construction site. Wall and roof panels, windows, doors, and joint fittings will be packed within the containers before shipping. Once the containers are delivered, our engineers will assemble them on-site based on the approved interior design scheme.


Container units are designed to be stackable, portable, versatile, and functional. No components are lost during assembly or disassembly. The modular structure can be moved an unlimited number of times. They can be assembled to include office space, bedrooms, dining rooms, bathrooms, entertainment rooms and so on.

GS Housing modular buildings can be designed as up to three-floor structures with no limitation on width. Therefore, modular buildings can be manufactured as many kinds of temporary buildings, such as construction camps, military housing, schools, hospitals, and transitional housing particularly for emergency situations.

Container structures are made from durable steel with a designed useful life of at least 20 years. The convenience and portability of the buildings makes them highly versatile.

  • Construction camp
  • Modular construction house
  • Containerized relocatable buildings
  • Container office
  • Temporary school buildings
  • Modular hotel buildings

Our flat-pack container structures are certified and delivered as standardized ISO intermodal containers, the most proven freight unit in the world today.

Standard dimensions

External dimension: 6055mm* 2435mm* 2896mm (length*width*height)
Internal dimension: 5845mm* 2225mm* 2780mm (length*width*height)
Tare: 2000 KG
Through the flat packaging, 4 cases of combined transport can be realized.
According to the wall structure form, it can be classified as a colored sandwich board panel container house, or a wooden frame and plate composite wallboard container house.

Shipping and delivery

The standard container that makes up the modular structure is suitable for international transport. It features appropriate external dimensions and has connections for lifting, fixing, or compounding. The container is designed as a light construction structure consisting of floor and roof frames and corner profiles. The construction enables compounding of individual containers in longitudinal and transverse directions without limits. It also enables compounding of containers in 2 floors in height (ground floor + first floor), or in 3 floors in height for warehousing of these containers (ground floor + 2floor).

The wainscots of the container are made of light insulation panels and offer pleasant climate inside due to their physical properties.

Delivery: Containers can be delivered assembled or individually in kits 660mm high. 4 kits can be bundled in packages 2640 mm high (ISO container dimensions)

Features of container

1. Container adopts hot rolled galvanized steel sheet for its frame, and incombustible materials for its walls. Meanwhile, all the basic designs, such as water heating, electrical appliances, and interior furnishing, are provided by our professional team and manufactured beforehand in our factory. No need for extra processing, they can be put to use after assembly.
2. Containers are easily assembled and disassembled in a short period of time. It could also be relocated according to customer requirements.
3. Heat preservation and sound insulation:
Wall panels adopt sandwich panels, which ensure good performance in moisture resistance, and heat insulation.
4. Containers can be used separately or be modularly designed as or multi-story buildings (up to 3). They could also be combined vertically or horizontally to meet the varying demands of the end users.
5. As containers are made from steel, they will withstand relatively powerful earthquakes.
6. Containers are pre-fabricated and possess great design flexibility with excellent energy saving properties, making the structures incredibly eco-friendly.
