Utilizing thermal water systems and incorporating the Areca plant, the design harmoniously blends agricultural productivity with community spaces for food preparation and engagement.
5 key facts about this project
01
Thermal water systems enhance energy efficiency throughout the building.
02
Greenhouse incorporates local biodiversity by allowing foreign plant growth.
03
Distinct thermal comfort zones are created using passive design strategies.
04
Community spaces are intentionally oriented to maximize sunlight exposure.
05
The design features a wall radiation system for effective heating management.

The project presents an integrated approach to functionality and sustainability within the context of agriculture. It addresses the needs of its environment while creating a balance between living and working spaces. The design focuses on thermal comfort and engages a variety of activities, showcasing how modern architecture can complement traditional practices in farming.

Thermal Comfort Zones
- Distinct thermal comfort zones are designed to cater to the different activities that take place in the building. Passive techniques such as the use of thermal water systems and specific color choices help optimize thermal conditions. Measures to protect from the elements encourage layering in clothing, which contributes to natural comfort and improved well-being for those within the space.

Spatial Arrangement
- Food preparation areas, including reception, dining, and multipurpose spaces, are positioned to make the most of sunlight. The choice of a south-facing orientation is essential for maximizing exposure to solar energy, aiding both energy efficiency and user comfort. The careful layout fosters interaction between agricultural production and daily living, enhancing the functionality of the space.

Greenhouse Integration
- The greenhouse is a prominent element that allows for growing various vegetables and flowers for the local market. This integration not only serves practical purposes but also introduces biodiversity to the area. The design is adaptable, accommodating foreign plant species even in harsher climates, which showcases its resilience and adaptability.

Ecological and Material Considerations
- Vegetation is thoughtfully chosen to enhance indoor air quality, featuring plants like the Areca and the Mother-in-Law's Tongue. These selections support a healthy indoor environment and reflect a commitment to natural design principles. Material choices, including down jackets and wool, serve to enhance warmth and comfort, acting as elements of thermal management.

Among the design details, a wall radiation system effectively increases heating surface area through a corrugated façade. This approach achieves a practical balance between environmental efficiency and occupant comfort.

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.
