Constructed with continuous XLAM panels and raw earth infill, the two-level guesthouse fosters community engagement while seamlessly integrating into the Umbrian landscape.
5 key facts about this project
01
XLAM panels provide structural support while enhancing thermal efficiency.
02
Raw earth infill panels reflect a commitment to ecological building practices.
03
Large south-facing windows maximize natural light and views across the landscape.
04
The design features a central square, encouraging communal interaction among guests.
05
A single-pitched roof design captures solar energy and reduces heat gain.

The housing module is located in the scenic region of Umbria, where the design integrates modern ideas with the area's historical architecture. It serves as a guest residence, aiming to create a relationship between the building and its natural surroundings. The overall concept focuses on a two-level layout that encourages interaction among guests and optimizes the use of daylight.

Design and Layout

The layout features two levels that promote a sense of connection throughout the space. An inviting staircase links the two levels, enhancing movement and engagement. Living areas are thoughtfully positioned to take advantage of views across the landscape, enriching the experience for everyone who stays there.

Facade and Light

Large south-facing windows are key to the facade, allowing generous amounts of natural light to fill the interiors. This not only creates a warm atmosphere but also connects the inside with the outside. The design includes a double-height living area, contributing to a feeling of spaciousness and encouraging relaxation and socializing among occupants.

Materiality and Sustainability

The structure employs continuous XLAM panels, providing structural support while also focusing on energy efficiency. Raw earth infill panels made from 120mm blocks add an ecological aspect to the building. These materials reflect the project's commitment to sustainability, combining contemporary methods with traditional practices.

Community Integration

The layout arranges guest houses around a central square, reminiscent of a medieval village. This design fosters relationships among guests, offering shared spaces while also ensuring privacy. The architecture demonstrates a thoughtful blend with the landscape, creating a calm retreat in the beautiful region of Umbria.

The choice of a single-pitched roof also plays a role in sustainability, capturing sunlight while providing shade during warmer months. The overall design shows an awareness of environmental needs, underscoring a commitment to living in harmony with the landscape.

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.
