Studio PROTOTYPE approaches architecture as a dialogue between structure and experience. In the Vertical Lofts project, this philosophy is translated into a design that merges architectural expression with interior atmosphere. Each space is conceived as part of a continuous spatial journey rather than a collection of separate rooms.

Vertical Living


The concept of verticality defines both the exterior and interior of the building. The three levels of the top apartment are connected by voids and staircases that create visual and physical interaction between the floors. This vertical connection enhances openness while maintaining a sense of intimacy within each level.

In contrast to the building’s raw concrete exterior, the interior design emphasizes warmth and tactility. A distinctive wooden core with fine, continuous detailing forms the heart of the home, guiding movement and creating a cohesive material narrative throughout the space.

Intimate Spaces


Studio PROTOTYPE’s design celebrates the human scale within an architectural framework. Small, sheltered corners integrated into the wooden core offer moments of retreat and reflection — demonstrating how thoughtful spatial composition can evoke comfort and connection within a modern urban context.
