5 key facts about this project
01

02
Features a spiraling design that provides uninterrupted views of the surrounding wetlands.
03
The roof is made from traditional thatch, integrating with the local landscape and culture.
04

05

**Project Overview**
Located within the Pape Nature Reserve in Latvia, Ligzda exemplifies a design that integrates ecological awareness with cultural heritage. The structure serves as an observation point for local wildlife and emphasizes the significance of the area’s natural and cultural narratives. Drawing on the local vernacular, the design adopts elements from traditional hayricks, combining contemporary and traditional architectural principles to create a meaningful connection between inhabitants and their environment.

**Spatial Dynamics**
Ligzda’s spiraling form rises from the landscape, allowing visitors to ascend gradually and engage closely with the surrounding wetlands and avian habitats. An observation deck at a height of 7.35 meters offers panoramic views, enhancing the birdwatching experience while maintaining a sensitive relationship with the ecosystem. The wooden support poles reflect local construction methods and underscore the importance of harmony with the natural surroundings.

**Material Choices**
The project prioritizes the use of locally sourced materials, emphasizing sustainability. Natural solid wood poles provide structural integrity, while thatch roofing made from local reeds establishes visual continuity with the landscape. Galvanized steel elements, including the spiral staircase and decking, add durability, further enhanced by the use of perforated sheet steel for rainwater drainage. Each material choice is deliberate, reinforcing the project's ecological and cultural commitments while ensuring resilience against environmental elements.

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.
