The Wavehouse is designed to promote a sense of calm and connection with the surrounding landscape. Situated in a lush environment, it serves as a retreat for meditation and self-reflection. The concept emphasizes the relationship between organic forms and nature, creating spaces that engage the senses and support individual well-being.

Design Approach

The approach to design focuses on creating an inviting atmosphere conducive to meditation. The building features a unique egg-cave-like structure that is both appealing and practical. As visitors approach the Wavehouse, they traverse a narrow path that draws their attention to the richness of the natural surroundings. This gradual transition encourages users to leave behind the busyness of daily life and prepare for a peaceful experience.

Structural Components

Geometric principles play a key role in the integrity and flow of the space. The exterior of the Wavehouse follows a Gaussian curve, while the interior employs a catenary arch. These forms provide strength while minimizing the amount of material needed. The layout allows for open areas that enhance movement and interaction, making it easy to navigate the space while appreciating its calming atmosphere.

Material Selection

One significant material used in the construction is rammed earth, known as Taipa. This choice reflects an understanding of how materials can impact comfort and sustainability. Taipa provides good thermal insulation, helping to keep the interior temperature stable. It also allows moisture to escape, which contributes to a healthy indoor climate. Using a natural material helps the building harmonize with its environment, emphasizing a connection to the earth.

Functional Organization

Every aspect of the building is arranged with care. The kitchen, shower, and toilet facilities are integrated into the hillside, reinforcing the bond between the structure and its natural setting. Storage solutions are designed to be discreet, with drawers built into the stairs, allowing for easy access to yoga mats and other items. This thoughtful organization supports practicality while enhancing the user experience.

The large deck extending from the zen-room offers a clear view of the landscape, featuring a water reservoir that serves both functional and aesthetic purposes. The water naturally filters, inviting visitors to engage with this calming element. This interaction with water enriches the overall experience of the Wavehouse, grounding it within the serene setting.

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.
