<A grid has no beginning, center, or end, the grid speaks through its logic of an infinite extension in any direction, generating a capacity to give continuity to what has been built, acting as a structure capable of organizing both small and autonomous elements as well as large sets>. Through this excerpt from the thesis: SUPRA ORDEN, / GRID COMO ELEMENTAL SUPPORT by Iñaki Harostegui, the work OUTSIDE-INSIDE is argued mainly through this strategy, which responds to some of the current themes of contemporary architecture such as the indeterminacy of the inner and outer limits.
