Repurposed Panels and Functional Cores in a Compact Off-Grid Home

Project in-detail

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 MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
