The purpose of this study is to develop an architectural and construction solution for protecting the civilian population in a multi-story residential building by creating a safe space with instant accessibility. The paper analyzes the past and present experience of designing and constructing civil defense facilities. An architectural and structural solution of the “safety capsule” − a form of protection of the civilian population of instant accessibility in multi-storey residential buildings has been developed based on the best practices. The safety capsule is a dual-purpose protective structure of instant accessibility, that can be used as a shelter during emergencies and as an auxiliary room in peacetime by the residents of the house. The options for detailed planning of the internal space of the “safety capsule” were designed. The proposed solution is integrated into the architectural and planning structure of multi-storey residential buildings by the example of 12-storey and 16-storey residential buildings.

Article is devoted to the investigation of suitability of low carbon Roman cement for restoration and finishing works. The history of the development of Roman cement as a natural hydraulic binder, which was commonly used to decorate building facades in the 19th and early 20th centuries, is presented. The properties of mortars based on Roman cement make it an excellent product for architectural restoration and conservation, as they are characterized by fast setting, high porosity typical for lime mortars, high resistance to weather conditions, high initial strength. At the same time, due to the high surface activity and increased water demand for cement, with the age of hardening, shrinkage deformations can develop, which leads to the formation of main cracks on the surface of the products. It is shown that the addition of gypsum is an effective regulator of the setting time of Roman cement and contributes to an increase in the strength of the cement paste. Analogs of Roman cement based on multicomponent cement binders modified with plasticizing and air-entraining additives are presented.

The palace in Kukizów of King of Poland John III Sobieski is known only to a narrow group of architecture and art historians. The palace and park complex ceased to exist in the 19th century. The architecture of the palace is known especially from the descriptions in the inventory documents from the early 18th century. Although the authorship of the palace design belongs to the well-known artists of the era - Augustyn Wincenty Locci and Piotr Beber, its architecture has not yet been reconstructed. A specific feature of the royal residence in Kukizów was the construction of royal buildings and town buildings in a wooden material. The intention to create a city complex and an entirely wooden residence was a unique experiment in the field of European architecture and urban planning of the 17th century. In the paper we present the results of our research on the architecture of the palace and town for the end of the 17th century. [ABSTRACT FROM AUTHOR]

The town of Zhovkva (Żółkiew) belongs to the late Renaissance foundations of private resident towns in Western Ukraine (Halychyna region) from the late 16th century. In accordance with historical sources, this city was founded by Stanisław Żółkiewski [2] in 1594. Urban-spatial structure of the town was designed according to the Renaissance ideal city. The city has a well-preserved original planning structure and a number of architectural monuments that are associated with it. The city consisted of two conjugated parts: the owner's castle and the fortified middletown. The combination of these two parts was of a specific nature - when the central square of the town is combined with the facade of the castle complex. On the base of the historical and urban studies presented the hypothesis that town of Zhovkva (Żółkiew) is an unique example of late Renaissance urbanism. The start of town build was in 1594 according to a project based on the concept of "ideal town" from the book of Italian architect Pietro Cataneo. We are thinking, that the author of the project and plan of town was Paolo Clamensi - Italian architect, worked in Lviv at the end of 16th century. The towns have a well-preserved original Renaissance planning structure and a number of architectural monuments that are connected with it. [ABSTRACT FROM AUTHOR]
