The Emmental Stairs was designed by Biljana Jovanovi'c, for a young creative family with an equisite design taste and an eye for details. They were just starting the refurbishment of their apartment and wanted interior stairs that would harmonize with the historic ambiance of the apartment and their aesthetic requirements, but also add an extra touch to their living space. 

Since it is centrally located in the apartment, it inevitably had to be treated as the focal points of the space. It provides certain level of intimacy without isolating these spaces.

The circular perforations on the sides let the sunlight seep through, creating surfaces that change the dynamics of the whole interior. The motif for circles was inspired by large windows that another focus point of the apartment. As they remind a lot of holes in cheese, the project was named Emmental Stairs.
