This study is dedicated to comprehensive approach to the problems connected with living in and operation of the old housing facilities stock of Madrid. The article provides a review to a developed area located in Colonia Ciudad Pegaso in Madrid. This area comprises two four-storeyed residential houses built in 1956, single-storeyed sheds and a small square. It has been found that as at 2017 the existing buildings do not meet the passive house criteria and the territory is not adapted to comfort living of people with limited mobility. Taking into account immediacy of this problem, the article offers the project for renovation of the area concerned. This project was developed within the regular urban program of Madrid called Mad-Re “Madrid Recupera” and the concept of sustainable development. During development of the project the requirements of Isover-Saint Gobain multi-comfort house were taken into account, barrier-free environment for comfortable living of different social groups was created, storage places were reorganized and the territory of the square was adapted to recreation of local citizens. As a result of the above works, there was created a new architectural appearance of the apartment block aimed at prospective development San Blas municipal district of Madrid.

The paper provides an overview of the existing structural and technological solutions for the construction of outdoor shelters over cultural heritage objects during restoration works in order to preserve from environmental influences and prevent external precipitation from entering buildings and structures. For these purposes, it is proposed to use standard solutions for various spans in the form of geodetic dome structures to protect buildings and structures from external precipitation and other atmospheric phenomena. The paper highlights the authors' work on the creation of new technical solutions for geodesic domes made of wood and high-strength polymers, which will significantly facilitate load-bearing structures, compared to metal and reinforced concrete. Also, the use of modern materials and technologies for the construction of protective structures will allow taking care of the environment, taking into account GREEN and ZOOM standards.

Introduction: In addition to recognizing and taking into account the vital need for the maintenance and repair of historical structures, this study will focus on their inherent design potential at the intersection of the new and the old. Purpose of the study: The study aims to review the approach to restoring such landmarks as the library in Vyborg and the Arsenal building in the Nizhny Novgorod Kremlin. We will also focus on the restoration of more mundane structures. In addition to historical monuments, this study will look at instances when there is no attempt to return the buildings to some idealized version of the past, but instead, the restoration process is used to celebrate the qualities of the buildings’ age in the here and now, and to recognize that they are living, evolving, and constantly changing entities. Methods: The study uses the method of analysis, which we apply to the standard solutions for various purposes and objects, in the form of structural and technological protection of cultural heritage sites during their restoration and adaptation. The use of modern restoration materials and protective structures’ construction technologies will help protect the environment while taking into account LEED, BREEAM, the Energy Star program (the USA), and the GREEN ZOOM standards. Results: We offer selected examples from contemporary practice in Europe, the United States, and Russia to illustrate these approaches to restoration, including two student-led architectural installations that explore the creative intersection between the new and the old. Discussion: Discussing the execution of specific restoration and reconstruction projects reveals the importance of international cooperation in the development of educational strategies and practices in the field of conserving and restoring the cultural heritage. The growing volume of conservation and restoration work is putting pressure on the development of research approaches and methodologies aimed at solving practical problems. At the same time, the restorer must be mindful of continuity with the past when reconstructing the more mundane and utilitarian structures that can benefit from less restrictive approaches to the intersection of the old and the new.

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.
