The Rammed Earth Pavilion is located in Phoenix, Arizona, close to a popular hiking trail. It provides visitors with a place to rest and reflect while connecting them to the natural surroundings. The overall design aims to foster a strong relationship between the structure and the landscape, highlighting the unique characteristics of the site through its thoughtful design choices.

Design Concept

The design promotes a connection between the pavilion and its environment by creating visual axes. These axes frame important views of the mountains and the nearby urban area, allowing visitors to appreciate both nature and built structures in the same sightline. Walls are arranged based on a stellar grid, enabling the pavilion to adapt to various contexts and serve multiple purposes.

Spatial Configuration

In the center of the pavilion is an octagonal room designed for exhibitions. This space is intentionally positioned lower than the surrounding areas, creating a more intimate atmosphere that encourages deeper engagement. The open layout of the walls helps merge indoor and outdoor spaces, enhancing the interaction between people and nature.

Materials and Structure

The pavilion primarily uses locally sourced rammed earth for its walls. This material not only provides a unique texture but also connects the structure to its geographical location. The ceiling consists of elevated wooden roof plates, made from timber boards of varying thicknesses. This combination supports a sustainable approach to construction while ensuring the design is resource-efficient.

Experiential Elements

The architectural arrangement of the pavilion offers different viewpoints for visitors, enhancing their experience of the space. Light plays a significant role, entering at various angles throughout the day to create changing visual effects. The design encourages exploration, allowing visitors to easily transition between indoor and outdoor areas, all while appreciating the outdoor landscape and urban views.

In the pavilion, the raised ceiling complements the walls, guiding the eye toward the expansive desert beyond, creating a continuous dialogue between the interior and the world outside.
