A topological ground-scraper that becomes a grounded sky-scraper

Eiroa Architects was invited by Kengo Kuma and Yusuke Obuchi to an International Competition for the Umeda area in Osaka, Japan. Eiroa Architects was pre-selected through a portfolio competition together with 20 international offices - only 5 from the USA / others local teams from Japan - to submit a proposal for urban redevelopment. Even though EA did not make it to the final selection (RUR, Dominique Perrault, UN Studio, Fuksas, and others) was honored to be part of such selective group of international experts. The final competition selection results were released as of 2014-03-27

A grounded ground is an artificial ground. A green artificial topography. A grounded building weaving through a grounded ground becomes a ground-scraper. A topological groundscraper-building. It is not ground nor it is a building. It is not not ground, nor it is not not building. A park with buildings. A park and not building. A park not building. A park as a building-park and a building as a park. A park and an underground building. A not building-park. A street and a park. A street and a building. A street building becoming a park. A park-building with grounded-buildings. A park-building with topographical buildings. A park-building with grounded buildings. Grounded buildings that emerge from a building-park. Grounded buildings that emerge from a double grounded ground. A double ground weaving sequence: A ground surface and a building surface. An undulating ground surface and an undulated building surface. A park building surface weaving upon itself. A double park building surface. A park building double surface that becomes a grounded building. A grounded building surface that becomes a de-grounded building. A tall building that emancipates itself from the ground surface. An elegant non-grounded ground-like building. A non grounded ground skyscraper.

The landscape interventions proposes a parametric topography displacing the natural grade reference level of the city of Osaka in Japan. The ground level is thickened and made inhabitable, providing different opportunities for diverse activities. The thickened parametric surface proposes topological continuous undulating spaces for public use. Private buildings that allocate diverse urban functions emerge out of the displacement and splitting of the ground surface.
