### Overview

Located in DeSmet, South Dakota, the Crossroads Tower is an architectural project designed to integrate the region's natural landscape and historical context. Serving as a waypoint for travelers along Highway 14, the tower encourages exploration while offering educational and recreational opportunities that engage users with their environment.

### Spatial Strategy and User Experience

The design emphasizes an interactive journey, guiding visitors through a network of thoughtfully designed pathways that promote a sense of discovery. These pathways lead to various viewing platforms, which provide extensive vistas of notable natural landmarks such as Big Slough and Silver Lake. Hidden rooms and secluded spaces encourage moments of pause, facilitating deeper engagement and reflection on the surrounding landscape. The overall layout includes a courtyard intended for community gatherings, while ensuring all pathways and spaces are ADA accessible, fostering inclusivity for all visitors.

### Material Selection and Structural Integrity

The choice of materials in the Crossroads Tower supports both aesthetic appeal and functional durability. The exterior is clad in weathering steel, selected for its longevity and ability to develop a naturally aged appearance over time, while supporting the structural integrity of the building. The use of steel grating on floors promotes visual transparency and sunlight penetration, enhancing user experience and safety. Additionally, a tube steel frame provides a solid yet flexible structure, allowing for efficient construction and maintenance, which aligns with sustainable building practices.

`
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.
