Applications of concrete are so common, while possibilities to shape – so unusual that it's hard to imagine a civilization in its present form, without its participation. It seems to be particularly invaluable in infrastructure projects. However, recently, in these applications, where it is directly exposed and interacts with the landscape, visual perception of concrete is changing and it is now increasingly being considered as a material brutal and uncouth in its technological sincerity. Opportunity to work out a new paradigm of practice for designing sustainable infrastructure is offered by technology based on biological methods. The process of artificial biocalcification of sand through ureolysis, otherwise called biocementation can be performed with use of some microorganisms such as, for example Sporosarcina pasteurii (former Bacillus pasteurii). Its result is reminiscent of natural sandstone rock. Very interesting opportunities open up for designers in shaping the spatial forms using this technology. In a natural way, it is possible to obtain structures resembling naturally occurring rocks, called tafoni. Their complex geometry causes that their construction of concrete by means of traditionally used techniques, would be either impossible or very expensive. It is also possible to apply biological cementation for surface hardening of large areas, e.g. the surface of the shifting sand dunes, to protect against movement. Inherent advantages associated with the concrete, combined with material formed in a biological process for forming complex spatial forms can be a significant factor in the humanization of the inhabited environment.

Sound exists in architecture and architecture exists in sound. The process of how the two have influenced each other can be observed throughout history and has brought us the most surprising outcomes. The article presents research results on the interconnection of sound and space, in the aspect of their intertwining influence in introducing physical changes in interiors and transformations in music. The objective was to present and scientifically describe a process in which both buildings and sound effect each other, inspiring new solutions, forming innovative structures and becoming both factors and subjects of their constant interaction. This correlation was investigated within a broad timeframe of European history, from the distant past – ancient Greece and Rome – to the recent future – a “vineyard” configuration of Berlin Philharmonic Hall. Several research methods were used, ranging from case and literature studies aimed at data gathering, to comparative and graphical analysis, discussion, and finally, the synthesis and critical analysis in the concluding part.A great example of the discussed phenomenon is the development of religious chant resulting from a long reverberation time in sacral buildings, creation of the polychoral technique connected to the architectural arraignment of St Mark's Church in Venice or the popularization of the “shoebox” configuration for music halls, as a consequence of wooden structural system's limitations. Let us have a closer look at the process of mutual influences between architectural space and inner sound

The work of Stéphane Du Chateau is clearly inscribed in the second half of the twentieth-century. Throughout his life, the famous engineer and architect developed and patented several spatial structure systems based on an ingenious design of nodes and skillfully applied them in the architectural form of various buildings. As of today, over 250 of his designs were successfully realized. Apart from the above, Stéphane du Chateau also established several associations in order to bring architects together and to promote Spatial Structures. His charisma and commitment brought a remarkable contribution to spatial structures.

The tense international situation caused by the war in Ukraine and the increase in global armed conflicts has led to a greater need for civilian protection. Since Russia’s attack on Ukraine in February 2022, neighbouring countries have taken measures to strengthen their defence, including civil protection initiatives. However, the availability and condition of shelter facilities in Central and Eastern Europe remain insufficient. This article aims to analyse the status of civilian shelters in Poland in the event of armed conflict and to establish design guidelines for these facilities. The research was conducted using available literature, studies on the construction and operation of shelters, and an analysis of recent government documents. When designing shelters for civilians, a comprehensive approach is crucial. Important factors should include the location, especially in urban areas, suitable functional and spatial planning, the potential use of shelters during peacetime, and their integration into a wider protection strategy.
