05
Clerestory windows maximize light penetration while maintaining privacy.

The summer cabin sits along a lakeshore in southern Finland, designed to blend with its natural surroundings. Positioned between the lake and the forest, it serves as a peaceful retreat for artists seeking inspiration. The design focuses on the relationship between light and space, creating an environment that enhances daily living and fosters a connection with the landscape.

Spatial Organization

The cabin features a layout that balances private and communal spaces, allowing occupants to transition easily between different activities. Areas like the sauna and the bedroom are thoughtfully designed with openings that maximize natural light, aligning with the occupants' needs throughout the day. This careful arrangement promotes a cozy atmosphere while still providing areas for gathering and socializing.

Light Dynamics

Light plays a crucial role in the cabin's design. The use of clerestory windows allows sunlight to enter without causing glare. This design decision ensures that the interior remains bright and welcoming, with a soft, diffused glow that changes throughout the day. The orientation of the cabin takes advantage of the low angle of sunlight during early mornings and late evenings, creating a warm ambiance that invites contemplation.

Materiality

The cabin's materials reflect the beauty of the surrounding nature. Inspired by tree trunks, the design incorporates smooth white cavities to enhance light diffusion. This is contrasted with a rough, dark exterior that filters sunlight while also maintaining privacy. These choices not only add to the visual appeal but also create a tactile connection to the natural environment, reinforcing the relationship between the cabin and its setting.

Seasonal Adaptability

The design takes into account the seasonal variations of sunlight common in southern Finland. This responsiveness to changing weather ensures that the cabin is functional year-round, from the short days of winter to the long, bright summer nights. By considering the local climate, the design creates a space that supports the occupants’ experiences, making it suitable for various activities and levels of comfort.

A calm courtyard at the center of the cabin invites light and shadow to interact, encouraging moments of reflection and connection with nature.

`
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.
