Tea House exemplifies a modern interpretation of a historical structure, emphasizing functionality while respecting its original context. Located within a verdant landscape, the design aims to rejuvenate a 1850s stone barn situated at the retreat site Ozonini. The architecture integrates elements from the existing building, preserving its historical significance while facilitating contemporary use for community engagement and wellness activities.

Purpose and Community Engagement

The Tea House serves multiple purposes, primarily as a venue for tea-related workshops, meditation sessions, and recreational gatherings. The design incorporates social spaces, including a kitchen, a living area, and dedicated workshop facilities, fostering community interaction. The spatial arrangement effectively addresses the needs of visitors, balancing social connectivity with private spaces for reflection and rest.

Design Approaches

One of the standout features of the Tea House is its fully openable glass facade. This design choice enables an unobstructed connection between indoor and outdoor environments, allowing natural light to permeate the interiors while providing extensive views of the landscape. The integration of a cylindrical window further enhances this relationship with nature, enabling dynamic lighting and contextual awareness within the building.

Material Selection and Sustainability Considerations

Additionally, the project showcases a careful selection of materials. The original quarry stone maintains historical continuity, while contemporary materials such as oriented strand board and trapezoidal metal sheets introduce modern structural elements. This duality of materiality serves as a visual narrative, melding past and present cohesively. The project also incorporates sustainability principles, such as reuse of existing structures, passive solar heating, and natural ventilation strategies, ensuring minimal environmental impact.

Distinct Spatial Zones and Inclusivity

The architectural design promotes various functions through distinct spatial zones. The lower level includes collaborative areas, like a kitchen and workshop spaces designed for tea preparation, encouraging communal activities. Meanwhile, the upper level houses sleeping quarters and a gallery for quiet reflection. This functional distribution caters to diverse user needs, highlighting the project's adaptability. Interior configurations include a wooden sleeping box on the upper level, which provides an intimate setting for rest, complemented by a gallery space that invites contemplation and creativity.

The careful articulation of spaces through defined zones maximizes usability while fostering an inclusive environment. The inclusion of outdoor terraces extends living spaces beyond the enclosed structure, allowing users to experience nature more intimately.

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.
