The Penumbra Pavilion is located in Ibirapuera Urban Park in São Paulo and serves as a space for reflection and contemplation. The design draws from traditional earth-building methods, allowing visitors to connect with the surrounding nature while enjoying a serene experience. The concept emphasizes a refuge that contrasts with the bustling city, aiming to restore a sense of calm through both architectural and environmental elements.

Architectural Concept
-
The pavilion features rammed earth walls that blend naturally with the landscape. This choice of material provides not just strength but also creates a tactile experience for visitors. A linear opening at the top lets in natural light, which transforms the interior throughout the day. This interaction between light and shadow adds a layer of dynamism, enhancing the visitors' experience as they move through the space.

Materiality and Construction
-
The walls are created from a mixture of sand, gravel, clay, and cement stabilizer. This combination highlights a focus on sustainability, promoting thermal comfort within the space. The building utilizes a wooden framework that is reinforced with shutters for stability. This approach to construction emphasizes traditional craftsmanship while adapting it to modern needs, allowing for precise adjustments during the building process.

Spatial Organization
-
The layout of the pavilion is arranged to encourage a smooth flow, guiding visitors toward moments of contemplation. Each area is thoughtfully designed to create opportunities for introspection and engagement with the surroundings. The arrangement facilitates interaction with both the architecture and the environment, encouraging visitors to be present in the moment.

As light filters through the pavilion, it emphasizes the textured surface of the rammed earth walls, highlighting the care taken in their construction. The design invites deep engagement, encouraging reflection on both the space and the natural world outside.
