Located in São Paulo, Brazil, the new building that houses the Rudolf Steiner University reflects the holistic principles of Waldorf pedagogy and its connection to nature. Spanning approximately 3,850 square meters, the building features a U-shaped layout that encircles a century-old mango tree centrally positioned on the plot. Preserving this tree was a primary challenge that guided the architectural design, orienting all spaces toward it. At the base of the mango tree is a central courtyard designed for student reflection and interaction with nature.

In our research into Waldorf-inspired architecture we noticed a strong emphasis on manual craftsmanship and the use of wood. However, due to the relatively compact size of the site, steel was selected as the structural material for its ability to span large distances without obstructing the ground floor, which is designed to be open and inviting. Wood was incorporated in two ways: literally, through an engineered wood structure attached to the slab system, which supports joinery facing the internal courtyard and converts into fixed student furniture; and symbolically, with the application of organic wood patterns on the metal cladding and shading devices.

The building’s program is distributed across three levels: the ground floor and two upper floors, each housing six classrooms. The pedagogical spaces were designed to be flexible, allowing for rearrangement based on evolving needs and offering greater usability. This flexibility extends to the vertical circulation, which is designed to encourage interaction and socialization. A rooftop terrace on the second floor provides a space for relaxation and socializing, with furniture designed for comfort and an unobstructed view of the surroundings.

Externally, two glass-enclosed panoramic elevators connect the floors and offer views of the mango tree and the surrounding area. The rooftop features a suspended block for administrative purposes, and the library is positioned at the highest point of the building, symbolizing its role as a beacon of knowledge and dedication to learning.
