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.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
