Microperforated steel panels and colorful voids define a new tower in Puebla de Fantova, offering versatile spaces for hostels, coworking, and residences.
5 key facts about this project
01
The tower incorporates microperforated steel panels for light filtration and privacy.
02
Colored glass voids enhance natural lighting and contribute to the building's aesthetic.
03
Setbacks in the perimeter pillars create a visually slender structure.
04
The design features distinct programmatic spaces identified by specific color themes.
05
Terraces and double-height spaces add dimension to the overall internal layout.

The design is located in Puebla de Fantova and features a tower that stands out in its landscape. It serves as a new landmark while engaging with existing elements in the area. The design centers around functionality with a free floor plan organized around a central service core. This setup promotes a flow of movement throughout the spaces and allows for a variety of uses.

Design Concept

The tower presents a solid exterior with perforations that create a balance between solid forms and empty spaces. These voids offer visual interest and allow natural light to enter, enhancing the experience inside. Terraces and double-height areas add complexity to the design, drawing inspiration from the organic shapes often associated with Gaudí. The use of color is also significant, contributing to the identity of the building.

Materiality

The building is constructed with thoughtful material choices. The perimeter wall consists of a 20 cm cellular block wall finished with plaster, backed by an equipped wall that measures 40 cm. Colorful voids are filled with glass that allows light to filter in while adding a visual element. The structural framework includes slabs, beams, and reinforced concrete pillars, ensuring stability. Perimeter pillars have setbacks, contributing to a slender appearance from different angles.

Programmatic Elements

Various spaces within the tower are identified by color, which reflects their specific functions. Green areas represent hostels, promoting a sense of calm. Blue zones are designated for coworking, encouraging energy and productivity. Residences are marked by purple, focusing on comfort and well-being. These color choices work with the arrangement of free floor plans, which enhance the sense of openness and connectivity.

Microperforated steel panels are used to control the entry of light, providing both illumination and privacy. This careful attention to detail in the design further establishes a strong architectural identity while enhancing the overall user experience. The interplay of elements throughout the tower creates a distinctive environment that responds to both the setting and its intended purpose.

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.
