Of the V&A extension Libeskind said: "That's moving in the right direction. We are looking to start construction as soon as possible."
Libeskind said he would continue pitching for other architectural work.
His practice recently won a competition to design a university building in Hong Kong and a retail scheme in Switzerland. He said: "I hope my life as an architect has not stopped."
Libeskind said he was also looking forward to overseeing his other major project in the USA, the Denver Art Museum.
Libeskind, speaking from his Berlin office, described his move to New York as "practical". He said: "I'm already spending more time over there than I am here."
Reacting to last week's win Libeskind said he was still on a high: "It's just a fantastic feeling."
