Chinese-based Sheraton hotel chain is planning an aggressive expansion in 2013, opening 30 new branches in the Asia-pacific area and four in Africa and the Middle East and 15 alone will open in China within the year. The “Sheraton Huzhou Hot Spring Resort” is perhaps the most striking of this endeavor, designed by Beijing-based architect Ma Yansong of MAD Architects. It could be described as horseshoe shaped, or maybe as a partially submerged bold serif-faced ‘O’, or even possibly a dipped elongated donut, but no matter how you describe it, the newly opened Sheraton Hushou Hot Spring Resort is not your average looking hotel.
