Elena Galli Giallini (EGGL), a Hong Kong-based firm specialising in architectural design, renovations, and interior and industrial design, has unveiled the rejuvenated north building of the Grand Gateway 66 retail complex (GG66), located in Shanghai’s bustling commercial, cultural and historical zone of Xijiahui. Comprising two distinct buildings of contrasting configurations, EGGL was commissioned to provide the prominent complex with a brand-new image, both architecturally and functionally. The result is truly spectacular with an unusual M. C. Escher ‘Relativity’ feel.
