Interchange is a contemporary design that harmonizes living space with the natural environment. Located near a lake, the setting provides a thoughtful backdrop for a cabin that is meant to encourage meditation and reflection. The design concept is rooted in the movement of the sun throughout the day, allowing natural light to play a significant role in shaping experiences within the space.

Design Concept
The main idea behind Interchange is to maximize sunlight exposure from morning to evening. This guiding principle influences the layout and orientation of the cabin. Openings are strategically placed to welcome in light. The result is a space that enhances the sense of calm and focus, making it ideal for those seeking tranquility in their daily lives.

Site Planning
Choosing the site was an important part of the design process. The area’s sparse tree coverage near the lake ensures that abundant sunlight reaches the cabin while also reducing the chances of mosquito disturbances. This decision illustrates a careful response to environmental factors, contributing to the overall comfort of the space and creating a deeper connection with the landscape.

Material Utilization
A key aspect of the design lies in the selection of materials, which balances practicality with environmental responsibility. Oriented Strand Board (OSB) is primarily used for both the exterior and interior. It is known for its durability and adaptability. Cellulose insulation adds to the efficiency of the building by helping maintain a pleasant temperature throughout changing seasons. Together, these materials support the architectural vision while committing to eco-friendly practices.

Spatial Organization
The interior layout effectively separates public and private spaces, encouraging both social engagement and personal reflection. This clear division is intentional, designed to suit different activities while keeping a cohesive feel throughout the cabin. Insulated windows enhance this experience, allowing sunlight to warm the interiors while preventing moisture from entering.

A notable detail is the way light and shadow interact throughout the day. The carefully positioned openings create shifting patterns that invite users to engage with their surroundings continuously. This dynamic quality enriches the living experience, making it more engaging and connected to nature.

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.
