Created by the renowned architecture and interior design studio Between the Walls, the showroom blends minimalism with playful, interactive elements to deliver a unique shopping experience.



One by One is a leading mass-market fashion brand known for its modern, accessible designs that empower individuals to express their individuality. 

Known for its collections that embody confidence and youthful energy, One by One has crafted a space that reflects these values. 



The design of the One by One Flagship Showroom was driven by an emotional desire to create the opposite of what many are currently feeling. As war and uncertainty in Ukraine weigh heavily on the population, the showroom’s designers sought to offer a space where lightness and joy could momentarily replace the weariness of everyday life.

“This project was a personal reception of the opposing emotions I’ve been feeling due to the ongoing war in Ukraine. Through the concept of the interactive pool and playful design elements, we wanted to offer an escape—a place where people could experience joy, ease, and a sense of distraction, even if just for a short while.”

At the center of the design is a modern, minimalist interior that feels light, inviting, and playful. The showroom’s white walls and tiled floors provide a clean backdrop for the curated clothing displays, while thoughtful accents and special installations add a sense of whimsy without distracting from the fashion itself.
