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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
