### Overview

Located in the prairies of South Dakota, the Prairie Smoke Tower functions as an observation point designed to harmonize with its natural surroundings while embodying the essence of the Prairie Smoke flower (Geum triflorum). The design is intended to enhance the visual appeal of the De Smet wetlands, serving both residents and visitors by providing a new vantage point from which to appreciate the area's ecological significance.

#### Design and Form

The structure exhibits an upward-tapering silhouette that mirrors the shape of the Prairie Smoke flower, culminating in a panoramic observation platform. A modular design allows for efficient on-site assembly and facilitates maintenance. The tower features various components, including leaflets, stairs, and viewing platforms, which work together to create a cohesive experience while promoting structural durability.

#### Materiality and Sustainability

Sustainably sourced wood, including local spruce for the leaflets and pine for the flooring and stairs, forms the primary construction material, ensuring both aesthetic appeal and long-term endurance. The use of perforated plywood introduces a balance of lightness and structural integrity, while hydraulic systems enable accessible movement between different observation decks. The design's integration with the local landscape emphasizes the ecological harmony of the structure, fostering an awareness and appreciation of nearby attractions, such as the Big Slough. By utilizing local materials, the tower reflects both its environmental context and a commitment to sustainable practices.

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.
