A mobile eave system enhances solar access and rainwater collection in a low-cost prism structure, constructed with cross-laminated timber and microcement, providing efficient residential space.
5 key facts about this project
01
Mobile eave system adjusts to seasonal sunlight and weather.
02
Integrated rainwater collection system optimized for efficiency.
03
Cross-laminated timber structure enhances structural strength and sustainability.
04
Unique bent A-frame design maximizes interior space and natural light.
05
Microcement finish provides durability and a modern aesthetic.

The project showcases a thoughtful approach to sustainable design, embedded in an urban environment that balances ecological care with social value. The focus is on a low-cost prism structure that efficiently serves its function while aiming to reduce environmental impact. The overall concept blends economic factors, ecological responsibility, and social engagement, creating a coherent response to modern architectural needs.

Sustainable Design Concept

The design begins with a basic rectangular prism, modified to enhance the use of solar energy and the collection of rainwater. Lowering one vertex creates a sloped surface that maximizes sunlight exposure and facilitates water harvesting. This clever solution enhances both the building’s functionality and its appearance, allowing for seasonal adjustments in light and climate management.

Ventilation Strategy

The project emphasizes an effective ventilation strategy that promotes natural airflow. Openings are thoughtfully placed at various heights, enabling cross ventilation throughout the interior. This design choice improves indoor air quality and comfort while reducing the need for mechanical cooling. The approach aligns with sustainable design principles by fostering a healthier living environment.

Material Selection

Materials have been chosen with care, ensuring both performance and environmental responsibility. The use of aluminium roofing sheets, cross laminated timber, and rigid thermal insulation are notable choices that reflect a focus on durability and energy efficiency. The Exterior Insulation Finish System contributes to the building's overall energy conservation, while microcement flooring, reinforced concrete, and extruded polystyrene foam enhance thermal performance and longevity.

Design Outcomes

The careful selection of design elements leads to a building that meets practical needs while engaging with its environment. The result is a structure that blends well with its surroundings and speaks to its purpose. The mobile eave serves as an effective shading system and protection against rain, adapting to varying weather conditions and enriching the user experience through its responsiveness.

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.
