Not exactly typical Norwegian architecture. It was the home of ship owner Erik Grant Lea.
Here is what Wikipedia has to say about him:
"Erik Lawrence Grant Lea (October 15, 1892 – April 28, 1979) was a Norwegian ship-owner, banker, insurer and mill owner. He became one of the most mythical tycoons of the boom years of World War I in Norway. Those that grew up in Bergen after World War II could hardly avoid hearing the fairy tale about Lea, a fellow citizen, who became the richest ship owner in the world, married an Indian princess, and then lost everything"
