## Kemeri National Park Observation Tower Architectural Design Report

### Overview
The Kemeri National Park Observation Tower is situated in Latvia, designed to enhance visitor engagement with the park's diverse ecosystems of forests and bogs. The intent is to create an accessible vantage point that fosters appreciation for the natural environment. The design reflects the interaction between the park's existing boardwalks and pathways, effectively encouraging exploration and awareness of the area's biodiversity.

### Spatial Organization and Access
The tower features a thoughtful spatial organization that prioritizes accessibility. Visitors can ascend and descend the structure using a series of ramps that connect three observation decks at different elevations. This arrangement not only provides expansive views of the landscape but also accommodates varying visitor needs, promoting an inclusive experience. The integration of ramps alongside a staircase allows for efficient circulation while maintaining structural integrity through an interconnected system of columns and suspension components.

### Sustainable Material Selection
The observation tower employs a range of locally sourced, sustainable materials, reinforcing a commitment to environmental stewardship. Primary structural elements include log columns that mirror the organic forms found in the adjacent forest. Sawn timber comprises the deck beams and floors, ensuring structural strength while maintaining aesthetic continuity with the surroundings. Other materials include Ultra High Molecular Weight Polyethylene (UHMWPE) fibers for tension systems, copper for roofing, and cohesive timber for handrails and decks. These choices not only contribute to the tower's durability but also enable it to harmonize with its natural context over time.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
