Emphasizing a curvilinear ramp and modular footbridge, the observation structure utilizes sustainable fir and OSB to create an accessible vantage point that enhances interaction with the natural landscape.
5 key facts about this project
01
Utilizes a curvilinear ramp design for seamless accessibility.
02
Constructed using sustainable fir and OSB for durability and ecological sensitivity.
03
Features a modular footbridge that connects to surrounding pathways.
04
Incorporates panoramic viewing platforms on each level to enhance experience.
05
Designed with a focus on integration into the natural landscape.

## Project Overview and Context
The observation tower is located within a landscape characterized by proximity to forests and wetlands, designed to enhance the visitor experience through an engagement with nature. The intent is to create a functional structure that serves as a focal point for outdoor activities and exploration, contributing to the site's value as a recreational destination.

## Structural Complexity
The design incorporates a robust structural framework composed of wood beams and circular piers, ensuring both stability and visual appeal. It features three distinct levels arranged to optimize views and facilitate movement. A curvilinear ramp provides a gentle ascent, enhancing accessibility for all users, including those with mobility challenges. The use of a plug-in construction method allows for quick assembly and adaptability, reinforcing the tower's role as a modern architectural solution.

## Material Selection and Sustainability
Material choices are integral to the project's efficacy, balancing aesthetic qualities with structural requirements. Fir wood beams form the primary support, offering both robustness and warmth, while oriented strand board (OSB) is utilized for ramps and flooring, ensuring durability and cost-effectiveness. Metal coupling devices enhance structural connections, promoting both stability and flexibility. Transparent wood finishes protect against environmental factors while showcasing the material's natural characteristics. The project adheres to sustainable practices by prioritizing the use of renewable materials and minimizing construction waste, ultimately reflecting a commitment to ecological responsibility.

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.
