With repurposed panels and dual functional cores, this compact off-grid home efficiently integrates sustainable solutions while providing comfortable living for young professionals.
5 key facts about this project
01
Two functional cores optimize space and organization within the compact footprint.
02
Repurposed sandwich panels enhance thermal performance and sustainability.
03
Dual orientation of functional zones aligns with exterior walls for efficient use.
04
Twelve photovoltaic panels provide a self-sustaining energy system.
05
An outdoor canopy expands living space and promotes connection to nature.

The Pied a Terre Microhome, located in Torla, Spain, addresses the need for compact living spaces designed for one to two young professionals. With a focus on minimalism, it moves away from the DIY aesthetic often found in tiny homes. The design prioritizes efficiency and functionality within a modest 25m² footprint, reflecting current residential needs in an ever-changing landscape.

Design and Spatial Organization

The layout maximizes usable space by employing two distinct functional cores. This setup allows for an increase in living area while keeping home functions organized along the exterior walls. An external canopy enhances the building's profile and provides extra storage options, alongside space for foldable furniture. This arrangement extends the living area beyond the confines of the building, effectively connecting indoor and outdoor life.

Material Choices

Materials play an important role in the construction of the Pied a Terre Microhome. The design features glass, wood, and corrugated aluminum, which create a cohesive and appealing structure. Repurposed insulated sandwich panels covered with locally sourced wooden slats enhance thermal performance and contribute to sustainability goals. These choices help in energy efficiency and blend the home with its natural surroundings, aligning it with the local architectural style.

Sustainability Features

Sustainability is a key aspect of the design, highlighted by the integration of twelve photovoltaic panels that enable a self-sustaining energy system. Climate control is handled by a heat pump along with floor heating, supplemented by a wood pellet fireplace for colder months. Rainwater purification and wastewater management are included, with systems in place to store water for everyday needs. Such features aim to reduce dependence on external resources while enhancing the overall livability of the space.

Functional Aspects

The interior layout encourages flexible use, making the most of limited space. Small kitchen and bathroom windows allow for natural ventilation, while a compost toilet provides efficient waste handling. This thoughtful organization ensures that residents can personalize their open living area, adapting it to their preferences and activities.

At the center of the home, the design of the canopy emphasizes the connection between indoor and outdoor spaces. It creates a sheltered area that encourages interaction with the surrounding landscape, enriching the living experience in a compact, efficient environment.

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.
