## Project Overview: Tower Mound, De Smet, South Dakota

Tower Mound is located near De Smet, South Dakota, and embodies a fusion of landscape architecture and public space through a tiered mound structure. The intent is to create a multifunctional space that encourages outdoor recreation and fosters community interaction while honoring the local ecological and cultural context.

### Spatial Strategy and Cultural Integration

The design features a terraced, spiral form reminiscent of ancient earthworks, connecting visitors to the historical narratives of the region. This gradual ascent, complemented by wide steps, enhances accessibility for individuals of all ages and abilities. The mound’s contours reflect the surrounding landscape, allowing for panoramic views that foster a connection to the natural environment. Additionally, the project acknowledges indigenous heritage, reinforcing cultural appreciation and discovery within its framework.

### Material Selection and Environmental Considerations

The project employs sustainable material choices that maintain the integrity of the landscape. Recycled concrete, bricks, and glass blocks form the core of the mound, while locally-sourced stone enhances both structural stability and aesthetic appeal. A variety of native grasses will cover the mound, supporting erosion control and promoting local biodiversity. Decorative metal elements will be integrated mainly around viewing platforms to enhance the visual experience without detracting from the natural scenery. Careful site placement minimizes disruption to local ecosystems and enhances educational opportunities regarding local flora and fauna. Access pathways are designed to be universally accessible, encouraging participation from the wider community while enhancing mobility for all visitors.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
