What more is to be said about Space? Inexhaustible in its meanings, potentials and inspirational capacities, this phenomenon has captured our attention for centuries. Looking broadly, more than a great number of topics, it unites disciplines and professionals in a constant search for the new answers. By proposed theme Radical Space In between Disciplines we aim at reaching educators, theorists, architects, designers, theatre practitioners, performers, artists, curators, writers, sociologists and all other professionals interested in this topic, to gather around our mutual interest - to offer opinions, to make statements, to share experiences, ideas and doubts. Seeking a debate on space as a radical, original, fundamental, extreme, yet overwhelming transdisciplinary phenomenon we aim at establishing new creative collaborations alongside a new holistic approach to the spatial perspective.
