if i could, i would choose to volunteer as a designer or an architect helper in singapore. i am fascinated by that little country. i believe, that it is the most beautiful place in the world. its contemporary architecture and urban planning is not comparable to any other countries. volunteering in singapore, would also contribute to my future career. i want to be an architect, and there is no other city, where architecture is developing that fast, and at that grate scale. as for a future architect, i do not know better country, for volunteering then a singapore.
