The aerodynamic form of a mixed-use tower, enhanced by energy-efficient e-glass, integrates retail and office spaces while harmonizing with the surrounding urban landscape.
5 key facts about this project
01
The tower reaches a height of 254 meters with 64 floors dedicated to diverse functions.
02
First four floors are designed specifically for retail, including two large cafes.
03
The integration of e-glass windows enhances energy efficiency and thermal performance.
04
The layout includes a 4,000 square meter mezzanine for flexible commercial use.
05
Three basement levels provide parking for 540 vehicles in a densely populated area.

The architectural design located between the districts of Kağıthane and Beşiktaş in Istanbul/Levent features a thoughtful approach to blending urban life with nature. The setting is characterized by a mix of high-density buildings and peaceful green spaces. The overall design aims to create a connection between these contrasting elements, producing a structure that fits well in its diverse environment.

Design Concept

At the heart of the design is the idea of 'leg,' which gives the tower its unique form. This aerodynamic shape supports not only the building’s structure but also its visual identity. The design responds to the needs of a modern city while considering environmental impacts. It reflects a careful balance of aesthetics and functionality, addressing both practical and artistic concerns.

Functional Layout

The project covers an area of 10,000 square meters, arranged to allow a range of uses. The first four floors are used for retail, including two cafes that together take up 16,000 square meters. This setup encourages activity at the ground level, promoting interaction among visitors. Above these, the fifth floor provides additional food options, while a mezzanine level of 4,000 square meters offers flexibility to the commercial spaces.

Height and Space Allocation

Rising to 254 meters, the tower consists of 64 floors with a total of 106,000 square meters allocated for executive offices and workspaces. This arrangement meets the demands of contemporary urban life, creating opportunities for businesses to thrive. Additionally, three underground levels are dedicated to parking, providing space for 540 vehicles. This feature is essential for addressing transportation needs in a busy area.

Sustainability Features

The project emphasizes sustainability through the use of e-glass windows. This choice helps regulate indoor temperatures by reflecting heat, contributing to energy efficiency. The design also includes protective coatings that guard against UV damage, enhancing the durability of finishes indoors. These sustainable features highlight a commitment to reducing long-term environmental impacts while maintaining practical aesthetics.

The building’s unique shape not only serves its functional purpose but also adds to the city’s skyline, representing a blend of nature and urban life.

`
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.
