A spiraling formation of glulam and steel rises above Pape Lake, providing multiple observation decks that enhance the visitor experience while fostering a deeper appreciation for the surrounding ecosystem.
5 key facts about this project
01
The tower's spiral design mimics natural forms, enhancing the connection to the surrounding ecosystem.
02
Constructed primarily from glulam, the structure emphasizes sustainability and resource efficiency.
03
Dual observation decks provide diverse viewpoints of the Pape Lake landscape and its wildlife.
04
Accessibility features are integrated throughout the design, catering to all visitor needs.
05
Informational panels enrich the visitor experience by connecting architectural elements to ecological themes.

## Project Overview

The observation tower at Pape Lake is designed to enhance the visitor experience while fostering an appreciation for the surrounding ecological environment. Standing approximately 50 meters tall with a 50-meter entrance walkway, the structure provides a gateway to the ecological landscape, allowing users to engage with the lagoon and its biodiversity. The design aims to create a contextual observation space that facilitates reflection and interaction with nature.

## Spatial Configuration and Experience

The tower features two panoramic observation decks positioned at varying heights, which offer distinct perspectives of the ecological surroundings without compromising the natural environment. The notched and spiraled form of the structure draws inspiration from natural growth patterns, thus creating a symbolic link between built form and ecosystem. This design approach also supports intuitive circulation, with spiral pathways guiding visitors through the observation levels and encouraging exploration.

## Material Selection and Sustainability

Materials selected for the tower emphasize both aesthetic and functional performance while promoting sustainability. Glued laminated timber (glulam) is utilized for its strength and lightweight characteristics, providing the primary structural framework. In addition, elements such as spruce lumber, steel angles, and rope systems are incorporated to enhance stability and durability. The use of wood contributes to a tactile connection with nature, while steel elements introduce modernity, together supporting the project's goal of harmonizing architecture with its ecological context.

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.
