Editor’s Choice 2025: OTIIMA Projects of the Year

As the year comes to an end, OTIIMA highlights a curated selection of projects that best represent the values we worked with. Editor’s Choice 2025 brings together projects that stand out for their design, technical demands, and intelligent use of windows in different architectural contexts.

From cultural buildings to private residences, these projects reflect a shared approach to architecture: precision, performance, and a strong relationship between space and light.

Osaka Pavilion | Kengo Kuma & Associates

The Osaka Pavilion was conceived as an immersive architectural space where movement and transparency are essential. The project explores openness through large glazed surfaces that guide circulation and connect interior spaces with the surrounding environment.

The integration of high-performance glazing supports the architectural concept and the functional requirements of a public building, ensuring comfort, durability, and visual continuity.

Bow | Ana Costa Arquitectura e Design

Bow is defined by its distinctive curved form, which requires a high level of technical coordination between design and construction. The project demonstrates how complex geometries can be executed with clean lines and minimal visual interruption. 

The glazing follows the building’s curves with accuracy, reinforcing the architectural intent while meeting demanding structural and performance standards.

Banánka House | Pauliny Hovorka Architekti 

Bananka House is a private residence where minimalism is expressed through proportion, material choice, and transparency. The project prioritizes a strong connection with the exterior while preserving intimacy within the interior spaces. 

The glazed openings are carefully positioned to frame views and improve daily living, supported by systems made for thermal efficiency and long-term comfort.

Seonhyewon | SKM Architects

Seonhyewon reinterprets traditional architectural principles through a contemporary approach. The project integrates solid elements with transparent surfaces, creating a clear spatial hierarchy and controlled visual connections. 

Our solutions are used strategically to connect spaces, enhance natural light, and support the architectural narrative without overpowering it.
