This paper explored the temporary facilities created during the pandemic for use as COVID-19 test centers at Zaventem Airport, the main airport for the city of Brussels, Belgium. The possibilities of modular construction technology and the impact of the building envelope on users’ perception of indoor space comfort and privacy were closely observed. The three main problem statements were as follows: (1) the COVID-19 crisis indirectly influenced the creation of temporary modular buildings with glass envelopes; (2) the modular envelope is adaptable to the existing context; and (3) the envelope meets the needs of the users. This study’s objectives were to identify the critical factors for users’ well-being in temporary modular buildings, and to conduct factor comparisons among different users and between different building-enclosure systems. The study data were collected through a subjective assessment using a SWOT analysis and a survey questionnaire. The glass facade affected the users’ acceptance levels of comfort and privacy. The main results show that the users were satisfied with the level of comfort and dissatisfied with the level of privacy. This information can be used to identify areas for improvement and provide useful feedback to designers and engineers about specific design features and operating strategies for temporary modular emergency healthcare buildings.

Based on the urban planning historical and comparative method, the paper gives a concise overview of the urban genesis of Ploče, a new port-industrial town, built in the 1945–⁠1990 period. As the youngest town on the Croatian part of the Adriatic coast, it developed after the demanding and extensive works on the regulation of the Neretva River and the construction of the Sarajevo-Ploče railway line to meet the needs of the port. Within the framework of social planning and on the basis of urban development plans, which involved mostly Croatian urban planners, a new town was soon built on a previously undeveloped rocky and swampy area. 80 years after the idea of a new town, the urban planning of Ploče undoubtedly represents the urban heritage of Modernism. The specific spatial identity can be presented for the needs of tourism and used for sustainable development planning.
