Incorporating rammed earth and a polycarbonate façade, this residential structure enhances energy efficiency while fostering community interaction through its thoughtfully designed layout.
5 key facts about this project
01
Rammed earth provides thermal mass and durability while minimizing environmental impact.
02
The polycarbonate façade allows natural light while insulating the structure from heat.
03
A two-bar layout separates living spaces from service areas, enhancing functionality.
04
Community spaces are integrated with outdoor areas to foster social interaction.
05
Natural ventilation strategies reduce reliance on mechanical cooling systems.

### Project Overview

The Long House is situated in Topanga, California, and has been designed to respond to the region's Mediterranean climate while promoting sustainable living practices. With an emphasis on community engagement and resource efficiency, the project incorporates a cohesive architectural approach that balances functionality and aesthetic integrity. The design is intended to facilitate adaptability and replicability in similar geographical contexts.

### Spatial Organization and Community Integration

The Long House features a dual-bar configuration that distinctly separates living and service areas. This organization allows for a flexible layout that can be adjusted to meet the diverse needs of occupants. Outdoor spaces are integrated throughout the design, serving as communal gathering areas while providing amenities such as bike storage and charging stations. The inclusion of natural ventilation and daylight strategies enhances environmental performance by reducing reliance on artificial lighting and HVAC systems.

### Material Selection and Environmental Considerations

In alignment with sustainable architecture principles, the Long House utilizes locally sourced materials, such as rammed earth, which offers thermal efficiency and durability. The outer polycarbonate façade permits natural light into the spaces while minimizing heat gain, thereby supporting energy conservation. A robust steel frame ensures structural resilience and facilitates efficient assembly. Additionally, the use of skylights and glass enhances the quality of natural light within the living areas, creating an inviting atmosphere that fosters interaction with the surrounding environment.

This project also incorporates ecological considerations, including planting grids for native flora and nesting sites for local wildlife, thereby reinforcing biodiversity within the urban landscape. The design promotes an integrated approach to living that prioritizes connection with both nature and community.

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.
