Constructed from locally sourced timber and crowned with thatch roofing, the spiraling observation tower offers panoramic views of the Pape wetlands, serving as a functional gateway for wildlife observation and environmental engagement.
5 key facts about this project
01
Constructed using locally sourced timber, enhancing sustainability and regional identity.
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
Elevated structure reduces ecological impact on the sensitive wetland habitat.
05
Incorporates perforated steel elements for drainage while maintaining visual connectivity.

**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.

Vancouver Tall Challenge: Building Higher Downtown

`
Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
