Design Drawings of Spherical Prefabricated Houses
Currently, there is no directly available specific content of the 'design drawings of spherical prefabricated houses', but the following relevant cases and design ideas can be used as references:
Case of the Bolwoning Residential Area in the Netherlands
The Bolwoning residential area in the small town of Den Bosch in the Netherlands is a typical representative of prefabricated spherical houses, consisting of 50 spherical buildings. Its core design is modular prefabricated structure: The bottom of the building is a cylindrical base with a height of about 1.5 - 2 meters, serving functions such as entrances, storage, and public facilities (e.g., access to water and electricity pipelines). Above the base is a sphere with a diameter of about 5.5 meters, which is divided into three floors inside by horizontal partitions. The upper floor is the living and kitchen area, taking advantage of the curved structure at the top of the sphere to create an open view. The middle floor is an independent bedroom, with circular windows ensuring natural light. The lower floor is the bathroom, utilizing the recessed space at the connection between the base and the sphere to arrange pipelines. This design uses on-site assembly of prefabricated components, shortening the construction period to one-third of that of traditional houses, and the spherical structure has a 40% higher wind pressure resistance compared to traditional rectangular buildings.
Design Concept of the 'House of the Future' in Finland
The 'House of the Future' series designed by Finnish architect Matti Suuronen in the 1960s is famous for its UFO-shaped prefabricated round houses. Its design features include: a single-story spherical structure with a diameter of about 8 - 10 meters, no load-bearing walls inside, and a central steel column supporting the dome. The spatial layout is flexible, with the living, sleeping, and storage areas arranged in a circular pattern around the central column, allowing users to adjust the furniture positions according to their needs. In terms of material innovation, it uses glass fiber reinforced plastic (GFRP) prefabricated panels, which weigh only one-fifth of concrete structures and have anti-corrosion and thermal insulation properties. Although only about 100 have been built, its modular design concept has influenced the development of subsequent prefabricated buildings. For example, modern spherical holiday houses often use similar detachable connection nodes.
Design Advantages of Spherical Prefabricated Houses
- Structural stability: Among spheres with the same surface area, the volume is the largest, which can evenly disperse external forces such as wind pressure and seismic forces, making it suitable for extreme climate areas.
- Construction efficiency: Prefabricated components are standardizedly produced in factories and only need to be assembled on-site, reducing construction waste by more than 60%.
- Space utilization: Without right-angled dead corners, the usable area increases by 15% - 20% with the same floor area.
If specific design drawings are required, it is recommended to contact a professional architectural firm or refer to the section on the design of special-shaped structures in the 'Technical Specification for Prefabricated Buildings' (GB/T 51231 - 2016).
