## Overview
The Superbloom observation tower is located near Silver Lake in South Dakota, aiming to honor local architectural heritage while promoting environmental awareness. Its design draws inspiration from the historical sod dugout houses that once provided shelter to pioneers in the region. The project emphasizes the importance of integrating contemporary architectural practices with the cultural and historical significance of the area, facilitating access for both local residents and tourists.

## Design Strategy
### Structural Integration and Materiality
The tower features an earth-sheltered design that subtly blends into the natural surroundings, reflecting the historical context of the dugouts. The use of recycled plastic lumber as the primary structural material supports sustainability while connecting the structure to its landscape. The visually striking façade, characterized by vibrant yellow sunflowers and a red exterior reminiscent of traditional barns, enhances the ecological aesthetic and further roots the design in local identity. Key materials include engineered lumber for modular construction, compressed earth blocks for sheltering, and marine-grade recycled plastic piles for structural support.

### Ecological Engagement
The project is designed with a focus on enhancing ecological awareness and community interaction. A network of pathways and footbridges facilitates exploration of the terrain, while gathering spaces foster community engagement. Features such as the "dugout trail," bird habitats, and irrigated green walls promote biodiversity and offer educational experiences centered on local ecology. Future phases will expand the project with additional habitat towers and interactive trails, further enriching visitor experience and wildlife habitats.

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.
