The concept aims to create a retreat that combines a sense of peace, safety, and security within a communal, temporary guest room. The main inspiration stems from childhood dreams of lofty, unreachable treehouses. In the imagination, a treehouse represents a place of refuge, where one feels safe and free to settle, isolated from the world. “The treehouse symbolizes childhood peace and innocence. It hides among the leaves, away from the evils of the world, allowing children to feel protected and secure in a ‘perfect’ little world they create for themselves.” This is essentially a temporary safe haven, where children can escape for a brief pause. The design draws inspiration from the concept of a Rubik’s cube, with many smaller cubes within a larger cube, and a connection between them, similar to this concept of different spaces within a single space. Just as the large magical cube represents the university, the smaller cubes within represent the students. The design consists of nine cubes, each 16 square meters in size and 4 meters high, in a milky white color. The cubes have two large windows that efficiently direct daylight in different directions. They are elevated on columns resembling tree trunks, at two different heights of 7 and 11 meters, and are connected edge to edge. Metal grids and two staircases link the cubes and provide access from the third floor of the Mozarteum’s main building. The cube and communal areas span two floors. Since the grid structure is transparent, it allows light to pass through, ensuring the entryway below remains well-lit. The cubes and columns are all connected by two separate platforms that house 24 small cubes, serving as seating and gathering spaces. These smaller cubes cover 70% of the platform area, protecting the seating cubes from rain like a canopy of trees.
