The article presents a study of modern achievements in the field of 3D printing of buildings and building components. The introduction describes a brief history of this technology. 3D printing technologies, in comparison with traditional building construction technologies, can be considered as an environmentally safe derivative, giving virtually unlimited possibilities for the implementation of geometrically complex projects. This article described two types of technology, and also noted that Contour Crafting is a promising technology that can revolutionize the construction industry in the near future. A brief description of several examples of innovative use of 3D printing in construction is presented. At the end, conclusions were made, tips and predictions were given on the use of 3D printing technology.

This article discusses the basic principles of the use of structural membranes in the reconstruction of buildings and structures. Three principles of intervention in the existing architecture are described in detail. The first is to preserve the historical appearance and character of the building. The second is the scale of the new and old parts of the building. The third is the difference and the possibility of reorganizing new designs. The characteristics of the goals, the achievement of which each of these principles is directed, are given. Using the example of several buildings, we analyzed the use of textile membranes to achieve the main goals of reconstruction, described the positive and negative aspects of restoration using textile membranes. These buildings include: a church on a hill in Corbera d'Ebr, Spain (roof restoration), the central courtyard of the Palacio de Mineria, Mexico (creating coverage over a yard area), Salzburg residence, Austria (sliding roof). In conclusion, conclusions were made about the advantages of using membranes for the preservation of historical heritage and possible prospects for the development of fields of application of this design.
