TanumKarl Johan is Oslo’s oldest bookstore located on the city’s main street. The project is a full renovation, which means completely tearing down the old interior. From having several floor levels, the store reappeared with all functions on one floor with a stronger visual relationship to the street and more rough materials to emphasize the physical appearance of the book.

The traditional green color of Tanum is continued into two shades; a dark green as a calm backdrop and the light green as a signal color. Elements from the Flag Ship Store at Karl Johan will give basis for other stores in the Tanum chain. The furniture is mobile and flexible, shaped to signalize actuality and be able to adapt to various actions and happenings at the store.
