In conjunction with the expansion of the East-West Free Passage in the Sendai Station Renovation Project, we promoted environmental design in the facility for the new East Wing expansion of the Espal Sendai Store East Wing and the renovation of the existing building schematic design under design administration of JR East, which is in charge of design administration. The plan was to expand the floor space of Stellnet I T and grand open the 2nd and 3rd floors of the main building in March 2016, and to open the 1st floor of the main building in March 2017 and Stellnet II in June 2017. We assisted working drawings and construction operations for the first three floors of the main building and schematic design for Stellne.
