Log House is a micro-home designed to address the challenges of resource use and environmental impact in construction. Located in a northern climate, it emphasizes a functional design that minimizes carbon emissions during its entire lifecycle. The project aims to redefine modern living by integrating energy efficiency and adaptability with traditional building practices.

Building Concept and Design Strategies

The design of Log House draws inspiration from historical building techniques, focusing on creating a structure that relies on locally sourced materials. It aims to meet energy needs through passive strategies. Sunlight is captured in the winter through south-facing glass doors that allow warmth to enter. The layout supports various functions, making it easy for different activities to take place within the same space.

Material Selection and Sustainability

Heartwood from pine is the primary material used in this building. It is chosen for its sustainable characteristics and natural resistance to moisture and pests. This material allows Log House to remain untreated, which lessens maintenance needs over the years. By choosing a single material, the design emphasizes efficiency and sustainability, reducing the overall environmental impact during construction and use.

Structural Innovations

The structure utilizes a modular approach supported by posts that are drilled into the ground. Logs are stacked within prefabricated tracks, which makes assembly straightforward. This method allows for quick construction and supports easy relocation to remote environments. At the end of its life, Log House can be disassembled and reused, aligning with the principles of sustainability and resource management.

Interior Flexibility and Functionality

Inside, Log House is designed for flexibility. The space can be used for multiple purposes, such as dining, working, or exercising. High ceilings and large windows create a feeling of openness, which counters the compact nature of the home. Natural ventilation through skylights helps maintain comfortable indoor temperatures without relying heavily on mechanical systems.

Log House represents a thoughtful approach to living that balances simplicity and sustainability. The focus on energy-efficient strategies and a careful choice of materials demonstrates a commitment to environmental responsibility in modern housing.

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.
