Mind Nest is a unique design situated in Latvia, located within an area known for its stunning forests and lakes. The building's concept takes inspiration from natural forms, particularly the nests created by various birds. This approach not only defines its appearance but also enhances its relationship with the surrounding nature. The structure serves as a dwelling while fostering a strong connection to the environment.

Conceptual Framework

The idea behind Mind Nest originates from analyzing the characteristics of bird nests. The design integrates a rigid wooden framework, reflecting the strength seen in wasp nests and incorporating the layered, woven forms of weaverbird nests. This combination results in a building that offers both stability and a sense of belonging in nature.

Spatial Dynamics

The layout emphasizes verticality, utilizing columns as key structural elements. These can be set against the ground or utilize existing trees for support, reducing material use and promoting environmental engagement. The design invites vertical growth, allowing various spatial configurations that move away from traditional layouts. Foldable walls create a strong connection between indoor spaces and the outdoors, providing occupants with changing views and lighting throughout the day.

Sustainability and Materiality

Sustainability is integral to Mind Nest. The structure is designed to operate independently for energy and water. It collects rainwater and harnesses solar energy, with resources stored in both a cistern and batteries. The materials chosen for the building include a lightweight wooden framework alongside thick hempcrete walls. This combination ensures energy efficiency and a minimal environmental impact. The exterior is finished with triangular wooden panels that resist harsh weather and blend naturally with the landscape.

Functional Layout

Inside Mind Nest, the layout is practical and efficient. Partitions create distinct areas for essential functions like food storage and dry toilets. Movement through the space is aided by a wooden spiral stair and a rope ladder, which save room while maintaining a clean look. The design enhances the experience of living in the forest, encouraging a sense of openness and connection to nature.

Mind Nest also features a fireplace, which supports the heating system along with a thermal solar panel on the roof for hot water. These elements reflect a commitment to sustainability and comfort, allowing occupants to live harmoniously within their environment. Ultimately, the building encourages a deep engagement with nature, promoting calmness and reflection.

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.
