Subscribers only
A glass-capped observation point provides a vantage over subterranean caves, inviting visitors to explore the interplay between the mountainous landscape and the hidden geological features below while serving as a public engagement hub.
5 key facts about this project
01
A glass observation point mimics the peaks of nearby mountains.
02
The tower is designed to create a dialogue between above-ground and subterranean environments.
03
A natural slope leads visitors from the landscape into the cave entrance.
04
Functional spaces include offices and public restrooms, enhancing usability.
05
The design emphasizes a double-height space for immersive viewing experiences.

The Skadi Tower is established in a landscape marked by seasonal changes and rugged mountains. It functions as both an observation point and a means to explore the caves beneath. The design aims to create a relationship between the structure and the surrounding nature, encouraging visitors to discover both the external views and the hidden depths of the landscape.

Spatial Experience

Inside the tower, a double-height space offers a sense of openness. Large areas allow for views of the landscape while also providing glimpses of the levels above. As visitors move up through the tower, the changing perspectives enhance their connection with both the open sky outside and the cave system below.



Transitional Elements

As one approaches the tower, a gentle slope leads to the entrance of the cave. This gradual incline serves as a natural pathway. It invites users to experience the rocky terrain and its features before entering the underground space. This thoughtful design helps to bridge the outside environment with the mysterious qualities of the caves beneath.



Functional Organization

The tower is organized to support various activities across different levels. The lower section is a hub of movement, including entrances to the caves, restrooms, and office space. This bustling area contrasts with the quieter, more reflective upper levels. This separation exemplifies an understanding of diverse user needs, balancing busy with calm.



Design Detail

At the top, the observation point features a glass cap that allows clear views of the surrounding mountains. This detail enhances visibility and strengthens the connection between the tower and its environment. The openness in this area invites visitors to appreciate the landscape while grounded within the structure itself, merging the experience of indoors and outdoors.

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.
