KA13 (Kristian Augusts gate 13)

KA13 (Kristian Augusts gate 13) is a groundbreaking project with reuse as the overarching goal. A modest office building from the 1950's has been preserved instead of demolished, and redeveloped with a new 8 storey extension using mostly reused building materials. KA13 has achieved a local reuse of ca. 80% and emission reductions of ca. 70% for the project as a whole. The project is a first in Norway's modern history to extensively employ the reuse of building materials. It sparked a movement within the construction industry, bringing attention to the regulatory challenges of implementing a circular economy. As a result, the government has revised national regulations to facilitate reuse.
