## Project Overview

Located in a subtropical desert environment, the Sanctuary microhome project is designed to promote sustainable living while addressing the challenges posed by its surrounding ecosystem. The intent of the design is to create a compact habitat that fosters community engagement and resilience, drawing inspiration from traditional architectural forms like oases and beehives.

## Material Innovation

Material selection is a pivotal aspect of the Sanctuary, aligning with the principles of sustainability and ecological compatibility. Notable materials include:

- **Palmifil Bricks**: Made from compressed palm fibers, these bricks enhance thermal regulation and are environmentally sustainable.
- **Finite Sand Bricks**: These eco-friendly bricks are designed to integrate harmoniously into the desert landscape.
- **Solar Control Glass**: Utilized for optimal light access while effectively reducing heat gain.
- **Aluminum Mullions**: Lightweight framing that supports structural integrity while contributing to the overall aesthetic.
- **Acoustic Ceiling Tiles**: Designed to improve comfort through noise reduction.
- **Photovoltaic Panels**: These ensure energy self-sufficiency by harnessing solar power.
- **Hydroponic Garden Systems**: Indoor gardens using advanced agricultural techniques for sustainable food production.
- **Insulation Materials**: Selected to enhance energy efficiency, particularly important for the temperature fluctuations typical in desert climates.

These materials not only contribute to the durability and aesthetic of the microhome but also promote energy efficiency and environmental harmony.

## Design Configuration

The Sanctuary's layout centers around a courtyard, which serves multiple functions including natural ventilation and shaded communal spaces. The compact design facilitates social interaction among inhabitants while addressing individual privacy needs. The hexagonal arrangement of units emphasizes community engagement, with a focus on shared agricultural practices that support local food sustainability.

## Environmental Features

Key features enhance the Sanctuary's alignment with environmental sustainability:

- **Fog Harps**: These devices collect atmospheric moisture, providing a passive cooling and water collection system.
- **Innovative Water Management**: Systems are integrated to recycle grey water for irrigation purposes.
- **Renewable Energy Solutions**: The design incorporates provisions for solar and wind energy generation, promoting energy positivity.

## Biodiversity Considerations

The landscape design emphasizes the integration of native flora and fauna, fostering biodiversity and ecological balance. The microhome's visual attributes are designed to complement and enhance the natural environment, ensuring compatibility with the surrounding desert ecosystem.

## Functional Adaptability

Interior spaces are designed with flexibility in mind, accommodating various daily activities—living, working, and entertaining—through adaptable configurations. This emphasis on multifunctionality is a critical consideration in compact living environments, enhancing the usability and context responsiveness of the microhome.

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.
