Spherical structures have been used by mankind since time immemorial in religious and public buildings, as well as in engineering structures. With the development of lightweight design and construction, non-standard architectural and planning solutions are used. More and more frequently they are being successfully implemented in private home projects and becoming a fact of everyday life. This may be explained by certain advantages of the form, as well as by the opportunities offered to the construction industry by the age of new materials and technologies for the works performance. The functional and architectural-structural design of round-shaped buildings in the form of geodesic domes will allow creating comfortable, cost-effective, energy-efficient and environmentally expedient conditions for human habitation taking into account the shortage of land areas and increased demand for alternative housing options due to the environmental situation around the world. This article analyzes the experience of building spherical buildings of different types and scales. The authors present the results of research carried out in the field of the geodesic dome design improvement with the use of wood and polymer materials.

Introduction: The use of modern construction materials and technologies makes it possible to take a different view of such long-span spatial structures as geodesic domes that seem quite familiar for architects and engineers. Methods: Based on studies of Russian and foreign researchers, the authors of the article suggest using the space between two geodesic domes for residential, administrative as well as laboratory and research facilities. Results: It is suggested to use this type of structures of wood and thermoplastics for rotational camps in the Arctic and Northern territories. Discussion: The authors conduct experimental studies to justify that it is possible to manufacture joint connections of various types of plastic.
