Timber panels pivot to control sunlight while framing expansive views in a community-focused space designed to encourage interaction and accessibility.
5 key facts about this project
01
Timber panels can pivot to adjust sunlight exposure.
02
The design incorporates a spiral shape for communal interaction.
03
Excavated land allows for unobstructed landscape views.
04
Large bay windows enhance interior-natural connections.
05
A green promenade surrounds the structure, promoting biodiversity.

The TreSpirala project brings together community needs and environmental awareness in a setting that encourages interaction and connection. Located in a picturesque landscape, the design includes three main areas: an event space, a kitchen, and a bathroom. The core concept revolves around a spiral shape, symbolizing continuous development and unity among users. This shape allows for an inviting and practical environment for various social activities.

Design Integration

The foundation of the design is based on a careful excavation that accommodates the interior spaces without blocking surrounding views. This strategy helps integrate the circular forms with the natural environment, making the transition between built and natural spaces smooth. Landscaped ramps promote accessibility, encouraging movement and interaction as people approach the building.

Materials and Sustainability

Sustainability is a key focus of the project, evident in the use of locally sourced timber. This choice reduces transportation impacts and supports local economies. Timber construction also allows for large bay windows that let in ample natural light, enhancing the connection between the interior spaces and the external landscape. The lightness of the timber contributes to a friendly and open atmosphere.

Ecological Features

The retaining wall, made with interlocking wooden cleats, supports gravel and soil while promoting plant growth. This design creates a green boundary that enriches the surrounding area and helps foster biodiversity. The wall serves not only a structural purpose but also enhances the visual connection between the building and nature, providing a more engaging experience for visitors.

Adaptive Sun Control

Large wooden panels are used along the facade to manage sunlight and maintain views of the landscape. These panels pivot on a central axis, allowing users to adjust the light levels according to their preferences. This flexibility increases the functionality of the central event space, adapting throughout the day and maintaining an open and inviting feel.

The TreSpirala project stands out for its ability to connect people with their environment. It encourages community interaction while respecting its natural surroundings, creating a space where both people and nature can thrive in harmony.

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.
