With the advancement of building industrialization and sustainable development, modular demountable buildings, as an efficient and environmentally friendly form, show significant potential in scenarios such as emergency housing and rural construction. However, they face issues including insufficient component adaptability, low demounting efficiency, and low integration level. Based on the Design for Manufacturing and Assembly (DFMA) theory, this paper proposes solutions and takes M-Box1.0 as a case study to explore design strategies from four dimensions: product modularization, logistics optimization, rationality of demounting, and component integration. The results show that M-Box1.0 has excellent ventilation and lighting performance. Compared with similar products on the market, it has fewer parts and lower costs. Moreover, it reduces construction waste through prefabrication and demountable connections. This study clarifies the advantages of DFMA-oriented design and has practical significance for promoting the efficient and energy-saving development of building industrialization.

The article deals with the issue of symbolism in contemporary architecture with facades made of precast concrete elements. The aim of the study was to demonstrate that such facades, beyond their structural and aesthetic roles, can also serve as a medium of communication, referring to the history of a place, local traditions, or the architect’s design intent. An analysis of more than 100 buildings was conducted on the basis of literature, project documentation, statements by architects and critics, as well as case studies. The findings identify four main methods of embedding symbolism: through the overall form of the building, the design of precast elements, the relief and tectonics of surfaces, and the structural system itself. The conclusions confirm that contemporary prefabrication is no longer limited to repetition and standardization but has become a tool of architectural narration, in which facades function as a system of signs, culturally and emotionally legible to the observer.

In Poland, residential architecture is dominated by so-called improved traditional technology. However, other technologies are used in different parts of the world, and they can be successfully adopted on the Polish construction market. The research described in this paper focuses on the influence of the type of structural system and thermal insulation material on the thickness of the envelope, typically for residential buildings, and consequently on the footprint or usable area of the building and its functionality. The study focused on three types of external wall systems: a two-layer masonry wall with rigid thermal insulation, a CLT wall with thermal insulation and a timber-frame wall with thermal insulation material. There were over twenty market-available thermal insulation materials chosen for the research. Our findings, although they apply to only a fragment of the subject matter, demonstrate the degree to which the type of structural system and insulation material can affect a building’s floor area, functionality and comfort of use..
