During these years in London he worked as an assistant at an architectural firm there.

When Nordan returned to Kristiania, he worked with his father until his death in 1892.

He focused his work as a hospital architect, and it was in this area that his business became most significant.

The hospital buildings from the time around the turn of the century are characterized by Art Nouveau style with simple facades where most of the articulation is done in yellow and red brick.

In 1926, his son Per Nordan joined his business where he worked until Victor's death in 1933.
