The egg-shaped structure, constructed with ecological cement and featuring photovoltaic yarn, efficiently integrates water management systems to create a compact micro-home that maximizes living space and sustainability.
5 key facts about this project
01
The structure features a unique egg shape that minimizes surface area and enhances energy efficiency.
02
Rainwater is collected through a corrugated shell design that directs runoff into a filtration reservoir.
03
The interior layout supports ergonomic living with separate zones for work and rest in a compact footprint.
04
Photovoltaic yarn is integrated into the dome, generating solar energy for improved sustainability.
05
3D printing technology is used to create complex surface geometries, allowing for innovative design solutions.

The Ovoid architectural concept offers a fresh perspective on micro-home design, emphasizing space efficiency and sustainability. Located within varied natural settings, the structure covers a compact area of 25m². It addresses the common issue of limited space in modern housing while creating an inviting living environment that meets contemporary needs. The overall design is marked by an egg shape, which enhances functionality and provides aesthetic appeal.

Design Concept

The egg shape of the Ovoid reduces the overall surface area, which contributes to higher energy efficiency and durability. This design allows for integration into different landscapes, strengthening the relationship between the built and natural environments. By using advanced 3D printing technology, the construction achieves intricate surface geometries in less time. This approach not only allows for a unique appearance but also aligns with sustainable building practices.

Spatial Organization

Inside the Ovoid, the layout features two distinct levels. The ground floor holds essential living spaces, such as a living area, kitchen, bathroom, and laundry room, along with additional storage options. The mezzanine level works to enhance the home's utility, providing space for a bedroom, workspace, and wardrobe. This thoughtful arrangement makes efficient use of the available space and helps promote comfortable daily living.

Natural Light and Water Management

Natural light is an important aspect of the Ovoid's design, achieved through six carefully placed windows. These openings allow plenty of daylight to fill the interior, creating an illusion of more space and maintaining a connection to the outside. The design also effectively manages rainwater with a corrugated shell that directs water into gutters. The collected rainwater is then stored for filtration and reuse, reflecting the project's focus on sustainability.

Materials and Energy Systems

The construction features ecological cement and reinforced elements, which provide strength and contribute to energy efficiency. Insulation is strategically included in the shell to help maintain a comfortable internal climate. The use of photovoltaic yarn on the dome’s surface is particularly notable, enabling the structure to generate solar energy. This energy system supports the goal of minimizing environmental impact.

Light streams through the dormer window at the top of the dome, illuminating the interior and emphasizing the unique curves of the egg-shaped design. The result is an inviting and well-lit living space that feels open, creating a calming atmosphere within the compact structure.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
