David lived in Hong Kong during his early years and was greatly influenced by high rise and modern buildings. The fascination with buildings remained as a young boy and at the age of 14, he started to pursue his ambition to be an architect. He returned to Hong Kong for year out placement and began working at Foster + Partners in 1993. The experience there had confirmed that architecture was his lifelong ambition realised. He returned to work at Foster + Partners, eventually qualified, and has not yet left since.
