Architekt miasta wczoraj i dziś - wizjoner czy administrator? Uwagi na temat roli architekta miejskiego w kształtowaniu wizji miasta
PublicationArtykuł jest próbą oceny roli architekta miejskiego od początków XX wieku do czasów obecnych. Opracowanie bazuje na pytaniu badawczym, czy we współczesnym mieście wciąż jest miejsc na wizjonerską i wiodącą rolę architekta miejskiego w kształtowaniu przestrzeni, jak to miało miejsce w przeszłości. Architekci miejscy są dziś raczej związani z pełnieniem funkcji administracyjnych, natomiast kwestie przekształceń urbanistycznych powierzane...

Evolution of Edges and Porosity of Urban Blue Spaces: A Case Study of Gdańsk
PublicationCurrent waterfront studies focus mainly on a land-based perspective, failing to include the water side. Water is, however, not just a resource for port and industrial purposes and an edge to the waterfront; it is also a feature of the waterfront and the complex relation between water and city. Thus, the article suggests that water-land edges need to be re-contextualised, taking into consideration also their shape, functionality,...

Urban Lighting Research Transdisciplinary Framework—A Collaborative Process with Lighting Professionals
PublicationOver the past decades, lighting professionals have influenced the experience of the night by brightly illuminating streets, buildings, skylines, and landscapes 24/7. When this became the accepted norm, a dual perspective on night-time was shaped and the visual enjoyment of visitors after dusk was prioritized over natural nightscapes (nocturnal landscapes). During this time, researchers of artificial light at night (ALAN) observed...

A city is not a tree: a multi-city study on street network and urban life
PublicationChristopher Alexander, a British-American scholar, differentiated an old (natural) city from a new (planned) one by structure. The former resembles a “semilattice”, or a complex system encompassing many interconnected sub-systems. The latter is shaped in a graph-theoretical “tree”, which lacks the structural complexity as its sub-systems are compartmentalized into a single hierarchy. This structural distinction explains why, or...

Typology of towns in the peripheries of Polish coastal regions: conclusions for urban policy
PublicationPeripheries means the land outside metropolitan areas. One of the main problemsin these areas is a lack of growth factors. Some towns can contribute to the developmentof these regions, because there are few such factors, and it is easier to create the newones, especially in urban policy.The subject of this paper is a typology of towns within the Polish peripheral coastalregions, limited to towns with more than 5 thousand inhabitants....

Surpassing the Line: Urban-Oriented Strategies in the Development of Business Complexes in Poland
PublicationDevelopment trends regarding the business-related urban complexes seem to evolve from the “big-box” towards the more “multi-use” types of structures. Within it, the special role is reserved for places, which—due to economic, political, and geographical reasons—have not been previously considered as major business hubs. Only recently, places like cities in Central and Eastern Europe have become attractive locations for business...

Tożsamość architektury jako odpowiedź na kontekst funkcji i miejsca na przykładzie budynku muzeum = Identity of architecture as a response to the context of function and place on the example of museum building
PublicationArchitektura starożytna, będąca przedmiotem dzieła Witruwiusza stanowi korzenie europejskiej myśli architektonicznej. Klasycyzm określił kanony i archetypy obowiązujące przez stulecia w projektowaniu muzeów. Wielowątkowość współczesnej sztuki, postęp w zakresie technologii budownictwa oraz dążenie do oryginalnością spowodowały odejście od jednej obowiązującej teorii i kanonu piękna w architekturze. Współczesne projekty muzeów reprezentują...
