5 key facts about this project
01
Unique movable floor system allows for flexible use of spaces throughout the day.
02
Greenhouse structure optimizes natural ventilation and enhances year-round usability.

05
Surrounding flower meadows create a private nature reserve, promoting biodiversity.

Set in the tranquil surroundings of Caramel Shore, the "Many Worlds" project offers a thoughtful approach that connects living spaces with the landscape. It features a greenhouse design that incorporates the Traveler Rooms, creating an environment that is comfortable and functional throughout the year. This structure enhances the user experience by blending indoor and outdoor elements, making it a unique living space.

Symbiotic Greenhouse

The greenhouse is a central aspect of the design, optimizing ventilation and creating a pleasant atmosphere during colder months. It allows for fresh air circulation in warmer weather through adjustable openings. The design not only serves practical needs but also promotes a close relationship with nature, enriching daily life.

Flexible Spatial Design

Inside the Traveler Room, a movable floor enhances flexibility. Users can rearrange the space from a bedroom to a dining area as needed. This adaptability supports various lifestyles and reflects a growing trend in modern living, where the function of spaces evolves throughout the day.

Ecological Integration

The swimming pond stands out as a significant feature, designed for natural self-purification. It incorporates selected plants and minerals, along with mechanical filters and sedimentation tanks. This approach not only supports recreational use but also demonstrates an awareness of ecological balance, highlighting the importance of sustainability.

Innovative Technology

Smart glass technology enhances the greenhouse by changing between opaque and transparent states with electric voltage. This feature helps to manage indoor temperatures during different seasons, providing comfort and energy efficiency. The thoughtful use of materials plays a vital role in creating a pleasant living environment.

A winding pathway through flower meadows encourages exploration and interaction with the landscape. This design detail not only connects different elements of the project but also enriches the experience of the area.

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.
