With its distinctive cone-shaped windows and structural waffle wall, the design creates an inviting light-filled space that serves as a private retreat within an urban environment.
5 key facts about this project
01
Distinctive cone-shaped windows enhance natural light while providing panoramic views.
02
Waffle wall construction allows for an open floor plan without intrusive support columns.
03
Spherical elements can expand and transition between indoor and outdoor spaces.
04
Utilization of lightweight framing reduces the visual weight of the structure.
05
Custom perforated metal panels contribute to the overall aesthetic and texture of the facade.

The Little Fringe House presents a unique approach to residential design, combining distinct form with functional living. Located in an urban alley between two large buildings, it stands out while also fitting into its environment. The design contrasts a dark exterior with a warm interior, creating a welcoming atmosphere. Upon entering, residents and visitors experience a shift as light and soft colors fill the space, inviting exploration and interaction.

Structural System

The design incorporates a concrete slab along with a pre-cast concrete waffle wall, creating a strong foundation. This structural choice allows for an open floor plan, minimizing the need for intrusive columns or walls. The result is a fluid living space that connects the different areas of the house. The waffle wall acts as a support for the second floor, which is secured in place by brackets and bolts.

Exterior Features

Cone-shaped windows are a notable characteristic of the exterior. These windows not only add visual interest but also allow natural light to brighten the interior. They frame views of the surroundings, encouraging a connection between the house and its urban setting. The design emphasizes this relationship and enhances the living experience within the home.

Spherical Elements

Spherical shapes are carefully integrated into the house’s design. These elements serve both aesthetic and functional purposes, providing additional living space that can change according to need. When in use, they open up to blend indoor and outdoor areas, allowing for greater interaction with the green spaces nearby.

Materiality

The building's design employs lightweight framing and metal paneling to keep its appearance airy. Custom metal panels, with perforations for added texture, contribute to the overall façade. This choice of materials maintains visual unity while providing durability.

The arrangement of spaces inside is designed to create cozy spots for quiet reflection, alongside larger areas for gatherings. This blend offers residents both privacy and a chance for social interaction, contributing to a balanced living environment.

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.
