Utilizing a substantial volume of repurposed concrete and integrating native plant species, this landscape design creates a multifunctional community space that emphasizes ecological restoration and social interaction.
5 key facts about this project
01
Incorporates over 72,000 cubic yards of recycled concrete into structural elements.
02
Utilizes a diverse selection of native, drought-resistant plants to enhance local biodiversity.
03
Features earth mounding that creates varied topography and distinct visual perspectives.
04
Integrates multiple gathering spaces for community engagement and environmental education.
05
Employs gabion construction techniques to merge structural stability with natural aesthetics.

### Overview
Located in De Smet, South Dakota, the project aims to repurpose a substantial volume of concrete rubble to establish a community space that harmonizes with the surrounding landscape. The initiative emphasizes ecological sustainability, focusing on both aesthetic and functional enhancement while addressing the pressing challenge of concrete waste. Approximately 72,832 cubic yards of rubble will be employed to create a permanent space that promotes leisure and activity, while also contributing to environmental health through strategic landscape management.

### Ecological Framework
The project is rooted in ecological restoration and community involvement. It focuses on the reclamation of an area known as "the slough," designing spaces that foster interaction with nature. The implementation of strategic planting initiatives aims to enable carbon sequestration, thereby enhancing the ecological benefits of the site.

The planned flora includes native, drought-resistant plants selected for their compatibility with the local ecosystem, such as Sugar Maple, Boxelder, and Big Bluestem. This selection aims to enrich biodiversity and minimize resource consumption while promoting carbon absorption over time, supporting the goal of eventual carbon negativity.

### Material Strategy
Utilization of materials plays a significant role in achieving the project’s sustainability objectives. The primary material is recycled concrete rubble, which will be formed into gabion blocks, providing structural stability and an organic integration into the landscape. Additional materials such as locally sourced soil, wood for walkways, and steel for structural resilience complement the overall design identity.

The layout incorporates wooden pathways and communal areas, facilitating movement and encouraging exploration. Features include viewing areas and amphitheater seating designed to host gatherings, fostering social interaction and community engagement. The varied topography, created through sloped terrain and earth mounding, enhances visual interest and provides diverse sightlines, further enriching the visitor experience.

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.
