## Project Context and Concept

The Tower of Rising Bubbles is located in Eastern South Dakota, near Silver Lake and the town of De Smet. This site, recognized for its historical importance and natural landscape, provides a relevant context for the architectural design. The intent of the tower is to represent the pioneering spirit associated with the region while promoting a connection to the local environment. Inspired by the experiences of early settlers, the design emphasizes themes of vitality and growth through its elliptical cylindrical form, which serves to engage the public with the surrounding prairie ecosystem.

### Material Selection and Sustainability

The project utilizes a range of sustainable materials that complement its ecological context. Key components include white oak wood for the columns and ramp, cross-laminated timber for the ramp boards and beams, and a dark colored oak wood outer shell. Additionally, a reticulated shell constructed from wood batten adds aesthetic and structural value. This material choice not only enhances the visual quality of the tower but also supports structural integrity while minimizing ecological impact, as all elements are suitable for prefabrication and efficient on-site assembly.

### Accessibility and User Engagement

The design incorporates several functional elements to enhance accessibility and user experience. A ramp with a 1:12 slope provides wheelchair access to the observation platform, which is elevated to 13.8 meters and designed to accommodate 12 to 15 visitors within a 14-square-meter area. This arrangement fosters community engagement while ensuring safety. Furthermore, the open design allows natural light and airflow, creating a harmonious atmosphere that encourages visitors to connect with the ecology of the area, particularly the diverse wildlife presented in the Silver Lake region. The project also emphasizes community involvement during the construction phase, strengthening ties between local residents and their heritage through collaborative efforts.
