Recycled timber forms a resilient structure designed for optimal thermal performance and passive ventilation, creating a sustainable retreat that seamlessly integrates with its forested surroundings.
5 key facts about this project
01
Recycled timber is utilized throughout the structure to enhance sustainability.
02
Cross-laminated panels provide superior insulation and structural integrity.
03
Charred wooden shingles ensure durability while minimizing maintenance needs.
04
Natural ventilation is achieved through a carefully designed passive airflow system.
05
The bent A-frame design optimizes thermal performance and aesthetic appeal.

## Project Overview

"The Hearth" is positioned within a densely forested area, designed to facilitate retreat experiences that foster a reconnection with nature. The architectural concept prioritizes a symbiotic relationship between the built environment and the natural landscape, incorporating advanced sustainability measures and thermal efficiency to ensure occupant comfort in varying climatic conditions. The design focuses on functionality while addressing contemporary ecological considerations.

### Spatial Engagement and User Experience

The layout of "The Hearth" promotes diverse spatial interactions, with distinct zones tailored for various activities, including social gatherings, solitary reflection, and creative pursuits. Central communal areas are oriented around the decentralized hearth, encouraging social connectivity while private spaces are intentionally designed for tranquility. Generous glazing provides unobstructed views of the surrounding forest, reinforcing the connection between indoor and outdoor environments and allowing natural light to penetrate deep within the interiors.

### Sustainable Materiality

The project utilizes an assortment of sustainable materials that reflect its ecological ethos. QuadCore LEC insulated panels offer exceptional energy efficiency through lightweight construction, while Trofikat™ vinyl ceiling tiles are crafted from recycled materials, contributing to the aesthetic and sustainability goals. Solatube tubular skylights enhance daylighting, reducing dependence on artificial illumination. Additionally, locally sourced recycled timber structures and polycarbonate panels facilitate thermal management while maintaining natural light access. Concrete cores are employed for both structural integrity and thermal mass, while integrated rainwater harvesting systems and clay plaster finishes further emphasize the project's commitment to sustainability.

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.
