The tower utilizes locally sourced cross-laminated timber panels, emphasizing sustainability and regional materials.
02
Charred wooden shingles are incorporated into the design to enhance weather resistance and aesthetic appeal.
03

### Overview

The Arbor Vista Observation Tower is strategically positioned near De Smet, South Dakota, within a landscape characterized by its ecological diversity and cultural history. Designed to function as both a viewing platform and a community landmark, the tower integrates into its natural environment while drawing attention to the region's rich ecological framework. The design intent emphasizes a dialogue between the built structure and its surroundings, fostering connections with local flora and fauna while underscoring principles of sustainability and ecological stewardship.

### Structural Expression and Materiality

The tower's design employs a modern yet organic architecture, with a series of triangular forms that ascend in a manner reminiscent of local trees. This structural approach not only enhances visual appeal but also embodies the project's commitment to echoing natural elements. Wood is the primary material used in its construction, sourced locally to minimize environmental impact and support regional economies. Steel elements provide structural integrity, while extensive glass applications enhance transparency and improve natural lighting conditions, promoting an immersive experience of the landscape.

### User Experience and Accessibility

Pedestrian circulation is facilitated through a central spiral staircase, which serves both structural and aesthetic functions, connecting various observation platforms. These areas are strategically designed to offer panoramic views, encouraging visitors to engage with the surrounding environment. The elevated positioning of the tower enhances visibility and accessibility, catering to a wide range of users while inviting interaction from different vantage points.

Incorporating advanced construction methodologies, the project utilizes prefabricated components that streamline assembly and contribute to overall sustainability. By prioritizing renewable materials and environmentally conscious methods, the design underscores a commitment to ecological responsiveness and community integration.

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.
