After discovering Santiago Calatrava’s art pieces in Valencia, Spain, I try to capture the America's Cup building by British architect David Chipperfield. I was, again, visiting these place while I was studying interior architecture, so I more paid attention to interior spaces at that time. Now, I can see more details of facades and exteriors spaces. The sketch was done looking through the building. The architect has garnered a great deal of awards, as has the building. Especially, the Royal Institute of British Architects awarded the highly coveted European prize in 2007. It was an enriching experience to see these buildings at that time, thanks to my aunt.
