Miasta krótkich dróg
PublicationNależy zrewidować poglądy na temat wielkopowierzchniowych obiektów handlowo-usługowych. Modernistyczne wizje miast zakładały tworzenie schierarchizowanych ośrodków usługowych - osiedlowych, dzielnicowych i centralnych. Socjalistyczne miasta nigdy w pełni nie wykształciły powyższych ośrodków. W wielu przypadkach ułomne struktury polskich miast zostały w ostatnim czasie dopełnione, niezbędnymi dla właściwego funkcjonowania, centrami...

X edycja Konkursu Studenckiego Akupunktura Miasta
PublicationWspółczesne miasto coraz częściej ulega rozpadowi na niezależne organizmy, połączone ze sobą jedynie korytarzami transportowymi. Obszary śródmiejskie tracą swoją rangę na korzyść rozrzuconych centrów handlowych, parków rozrywki, subcentrów dzielnicowych. Podejmowane od II połowy XX wieku całościowe programy rewitalizacji miast, okazały się być zbyt drogie by objąć swym zasięgiem całe zdegradowane struktury. Obecnie podejmowane...
