Islam versus Architecture and Urban Order in the Time of Changes : Social and Cultural Aspects of Housing Architecture Transformation in the Arab Countries of Northern Africa
PublicationArtykuł jest omówieniem obserwacji tradycyjnej i współczesnej zabudowy mieszkaniowej przeprowadzonych przez autora w Algierii (1978) i Libii (1984-1988). Realizowane obecnie struktury i kultywowane formy zamieszkiwania wzorowane są na rozwiązaniach ''zachodnich'' odmiennych od rozwiązań tradycyjnych. Są one niedostosowane do wymogów środowiska naturalnego i pozostają w sprzeczności z zasadami określonymi przez Koran i sunnę. Rozdźwięk...
