The Water Mill Shelter is an innovative construction that engages with river environments in northern Chile. It utilizes a hydraulic system inspired by the azuda wheel, generating energy through the rotation of its main rings. This design functions as a home and an agricultural laboratory, demonstrating how to live sustainably and efficiently by making the most of available natural resources.

Conceptual Framework

The design consists of a modular configuration with concentric rings and a central distributor, allowing for an organized arrangement of various functional spaces. Areas are designated for agronomic research, supporting the study of traditional greenhouse methods. This integration emphasizes the project’s commitment to sustainability while also creating opportunities for education in innovative agricultural practices.

Water Management System

A significant feature of the Water Mill Shelter is its advanced water management system. It includes components such as water tanks, floatators, gutters, and greenhouses, designed to effectively use the local water supply. By supporting hydroponic cultivation, it reduces the need for land while increasing agricultural productivity, embodying modern approaches to sustainable farming.

Structural Elements

The construction employs wood beams and lateral beams, contributing to both the durability and warmth of the interior spaces. These materials enhance the overall stability of the structure while fostering a connection to the natural landscape. Features like retractable windows improve airflow and allow natural light to enter, creating an ongoing relationship between indoor and outdoor environments.

The design clearly reflects an intention to integrate human living with natural systems. Thoughtful planning and carefully considered elements work together, supporting both habitation and on-site agriculture in a cohesive manner.

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.
