In October of 2011, the Stockholm city museum blue-marked (highest ranking) the building,which gives it a strong protection against deconstruction and contamination. The building curator's motivation was that "Since the school has created such a great emotional involvement and feelings since its construction, it is of great importance in cultural history. The building is a search after a sort of primeval architecture, that is so pure, without as little colour as possible and added details." In the final report of Mejan Arc \ Restorational art (society) of the Royal University in 2013, the school is presented as one of the era's most thoroughly thought through and implemented construction works, executed according to its time's architectural ideals, with a clear place in the architectural history of Sweden. The building is also said to have a huge historical value for its time's changing societal climate, as architectural focus went from empirical studies to social issues and ideas of a democratic and non-hierarchical school.
