Sustainable Development of Water Housing Using the Example of Poland: An Analysis of Scenarios
PublicationAt the turn of the 20th and 21st centuries, Polish cities began the process of returning to live by water. There is a growing interest in water reservoirs not only as places for recreation, but also as new areas suitable for living, at the very center of the city. Unfortunately, due to the lack of appropriate legal regulations, the dynamic development of floating homes (FHs) is starting to raise increasing concerns in Poland. Regardless...

ARRIERE-GARDE IN ARCHITECTURE, AS A RESPONSE TO POST-POSTMODERN REALITY
PublicationThe article presents a general discussion on the direction of contemporary architecture. We can freely speak that postmodernity, understood in its philosophical core as a search for meaning in architecture, as a strategy of building our environment is over. What comes next? Some say, from lack of better naming, that we live in post-postmodern times. Term post-postmodernity is a call for new strategy of shaping our societies and...
