## Project Overview
Located in an environment conducive to exploration of sustainable living solutions, Architectonicidae is a microhome project that utilizes contemporary design and construction techniques. Drawing inspiration from the organic shapes of seashells, the design integrates advanced aspects of 3D printing with a focus on creating a harmonious yet functional living space. The project emphasizes sustainability and adaptability, seeking to redefine traditional notions of shelter through its innovative approach to architecture.

## Layout and Spatial Configuration
Architectonicidae features a circular layout that facilitates efficient space utilization while promoting comfort and privacy. The central living area consists of essential amenities—kitchen, dining, and storage—arranged for accessibility. Adjacent to these communal spaces, enclosed areas provide privacy for residents. Vertical sections of the structure are designed to enhance the feeling of openness, with large windows that allow natural light to permeate interior spaces. This configuration not only aids in ventilation but also reduces the need for artificial lighting, fostering an environment that prioritizes well-being.

## Material Selection and Environmental Integration
The project employs a carefully curated composite material for its construction, primarily utilizing 3D printing technology to create the shell structure. The material composition includes local silt, sand, and lime, which contribute to both the structural integrity and thermal performance of the dwelling. The roofing system incorporates a translucent Kingspan design, allowing natural light and accommodating solar panels for energy generation. Additionally, reclaimed wood flooring enhances the project's sustainability aspect while offering a warm aesthetic.

Architectonicidae also integrates various systems aimed at environmental efficiency, including solar energy collection and a rainwater harvesting system that minimizes waste runoff. The eco-friendly toilet system processes waste into compost, reinforcing the project’s commitment to sustainable living practices. These features reflect a comprehensive strategy to minimize environmental impact while maximizing resource use.

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.
