OASE, Journal for Architecture is celebrating its 25th anniversary. During this time, OASE has evolved into an international professional journal in which a reflective and critical approach to architecture, urban development and landscape architecture is the mainstay. This jubilee is being marked by a special edition of the journal. OASE #75 is a compilation of the most important essays and background articles published in OASE over the last 25 years in a double-thick English-language edition, making a great many key texts accessible to an international readership for the first time. This anthology affords an overview of the themes that have dominated architectural discourse in the Netherlands, Belgium and beyond over recent decades. The themes are set in a broader context by introductory texts and reflections that have been specially written for this issue by prominent architecture historians. This publication therefore constitutes an important source of information on developments in academic debate as well as professional practice in the fields of architecture, urban design and landscape architecture.
