German Prefabricated Assembled Houses
The development of German prefabricated assembled houses has gone through multiple stages, with diverse and constantly advancing technologies.
Early Development: Prefabricated construction in Germany emerged in the 1920s. Driven by the acceleration of urbanization and changes in architectural aesthetics, standardized prefabricated concrete panel construction technology came into being. Its efficient and cost-effective characteristics were favored by the market. For example, the housing area for war-disabled soldiers built in the Lichtenberg-Friedrichsfelde district of Berlin from 1926 to 1930 was an early representative.
Post-World War II Development: After World War II, Germany faced the dual challenges of war damage and the return of refugees, and the housing problem became prominent. To quickly meet housing demands, a large number of houses were built using prefabricated concrete panel technology. However, due to a lack of maintenance and updates, these panel buildings gradually lost their appeal. Today, many such areas have become key targets for urban renewal and renovation.
Current Technological Progress:
- Concrete Composite Wall Panel Technology: This technology is widely used. When constructing public buildings, commercial buildings, and multi-family housing projects, more attention is paid to adapting to local conditions. Appropriate construction systems are selected based on project characteristics, which may involve a combination of cast-in-place and prefabricated components or the flexible application of steel-concrete structures.
- Modular Combinable Prefabricated Houses: A company offers such houses with a basic structure composed of reusable steel container modules. Through a serial and efficient production process, these are pre-assembled into plug-in building modules, which are then combined into modular living units. These units can be further assembled into building complexes. The construction concept emphasizes resource conservation and recycling. The houses are made of 100% reusable, recyclable, or eco-friendly building materials and are completely detachable. After the end of their service life, reusable components and recyclable secondary building materials and components can be recovered for use in new houses. At the same time, each 'container' house has a digital building passport that includes the building serial number, energy and QNG sustainability certificates, CAD construction plans, and complete resource documents.
- Wooden Prefabricated Houses: These are gradually entering the public eye, with examples of extremely fast delivery. The internal structure includes guest bathrooms, workrooms, storage compartments, stairwells, kitchens, dining rooms, living rooms, etc., with reasonable design and complete functions.
